Overview
The Trans-Catalina Trail is unusually approachable without being easy: developed campgrounds and ferry access simplify the logistics, while the climbs, dry terrain, strong sun, and long days still make it feel like a real backpacking accomplishment.
The trail was more scenic than I expected. Ocean views appeared frequently, and higher ground near the middle of the island opened broad panoramas with coastline visible on both sides of Catalina. In clear conditions, the California mainland sat faintly on the horizon. Bison and an island fox added a wildlife element that felt entirely distinct from my other trips.
Little Harbor and Parsons Landing were the strongest camps. Both put the route directly beside the coast, and cowboy camping under clear January skies became one of the trip’s highlights. Little Harbor delivered the sunset; Parsons Landing delivered the stars, waves, and a beach sunrise after the hardest day.
This is not a pure wilderness experience. Designated campsites, potable water during our trip, toilets, picnic tables, roads, town stops, and ferries remove many of the usual logistical barriers. That accessibility is part of the route’s value, not something to apologize for. The walking still includes sustained climbs, dry exposed ridges, steep descents, and substantial sun exposure. Day 3—Little Harbor to Parsons Landing via Two Harbors—was an especially demanding sequence of climbing, descending, mileage, and heat from the sun.
The route can work well for newer backpackers when someone in the group understands basic trip planning. Experienced backpackers can also enjoy it, provided they come for island scenery, wildlife, and beach camps rather than complete solitude. The infrastructure lowers the logistical difficulty; it does not make the trail effortless.

Trailhead & Access
| Start | Avalon |
| Finish | Two Harbors ferry terminal |
| Primary Airport | LAX |
| Pre-Trek Base | Long Beach area, then one night in Avalon |
| Island Transport | Catalina Express from Long Beach to Avalon; return from Two Harbors to San Pedro |
| Vehicle | No rental car or vehicle shuttle required |
| Direction | Avalon to Two Harbors worked well and created a progression from Blackjack to the more scenic Little Harbor and Parsons Landing camps |
My access setup: I flew into LAX, stayed near Long Beach, and took the ferry to Avalon the next day. I spent one night in Avalon before hiking. The Long Beach hotel agreed to hold my non-backpacking luggage, so I brought only trail gear to the island. Confirm luggage storage directly with your own hotel rather than assuming it is included.
Return and direction: After finishing in Two Harbors, I took the ferry to San Pedro and returned to the Long Beach area to retrieve the rest of my luggage. The trail can be hiked in either direction, but Avalon to Two Harbors fit the transport and gave the camps a stronger progression, with Parsons Landing as the final overnight payoff.
Getting There Without a Rental Car
A point-to-point island crossing that works cleanly with flights, ferries, and local ground transportation—no vehicle shuttle required.
The Trans-Catalina Trail is unusually convenient as a destination backpacking trip because the point-to-point route does not require a rental car. From LAX, use rideshare or another ground-transport option to Long Beach and stay near the ferry terminal if practical. Take the ferry to Avalon, hike across the island, and return to the mainland from Two Harbors through San Pedro without arranging a vehicle shuttle.
Planning note: Book ferry transportation around the hiking itinerary and verify which mainland ports serve Avalon and Two Harbors on the required dates. Catalina Express currently lists Long Beach–Avalon and San Pedro–Two Harbors service, but routes and frequency vary by season. Check the official Catalina Express schedule. TODO: confirm the date-specific ferry links and schedule notes before publication.
Campground Reservations and Logistics
Designated camps simplify the route, but the reservation sequence should be secured before flights and ferries are locked in.
Reservations are a core part of planning the Trans-Catalina Trail because camping is limited to designated campgrounds. Every overnight stop on this January 2025 trip—Blackjack, Little Harbor, and Parsons Landing—was reserved in advance, with specific campsites selected. The campgrounds were not overcrowded during the trip.
The Catalina Island Company currently handles campground booking, while the Catalina Island Conservancy currently requires a free hiking permit. The official camping page currently says online reservations for the coming year open January 5 at 8:00 a.m. Pacific, with January and February reservations available by phone beginning December 1. Verify both processes before booking flights or ferries: use the official Catalina camping page and Conservancy permit page. Release timing, the booking platform, cancellation rules, campsite capacities, and the relationship between campground reservations and trail authorization can change.
Draft TODO: Recheck reservation-release details and the current booking workflow; add exact campsite numbers; verify the current permit workflow, campground water status, food-storage facilities, and toilets immediately before publication.
Route Guide
Four days from Avalon to Two Harbors, with overnight stops at Blackjack, Little Harbor, and Parsons Landing.
Day 1: Avalon to Blackjack Campground
A steep opening climb out of Avalon leads into rolling interior terrain before the first night at Blackjack—10.61 mi, +3,082 ft / -1,598 ft.
Route
Begin in Avalon and walk through residential streets toward the Hermit Gulch area, passing near Hermit Gulch Campground before climbing steeply away from town. Views back over Avalon and its harbor improve quickly with elevation. The opening climb makes the trail feel serious almost immediately, even though civilization remains close below.
The route continues through the dry island interior on dirt trail, with some wider road-like sections, to Blackjack Campground. Although this is a moderate day compared with Day 3, the repeated rollers after the opening climb bring the CalTopo total to more than 3,000 feet of ascent.
Blackjack Campground
Blackjack was the least memorable of the three camps, though still comfortable. Designated sites sat close enough that other campers were likely to remain within sight or earshot, but it did not feel packed. My site had a picnic table, potable water was available during the trip, and an enclosed structure held a vault-style toilet with toilet paper. Carry backup toilet paper regardless.
The campsite had a modest outlook and a pleasant evening, but neither sunrise nor sunset became a major trip highlight. No animal problems occurred. Current official information lists water and bathrooms at Blackjack, and current rules prohibit fires there.
Amenity check: Confirm the current food-storage facility and water status shortly before departure; do not assume every January 2025 amenity remains unchanged.
Day 2: Blackjack Campground to Little Harbor
Airport in the Sky breaks up a mostly descending day that finishes at the more scenic Little Harbor coast—8.04 mi, +984 ft / -2,467 ft.
Route
Leave Blackjack and continue west through the island interior toward Airport in the Sky, then cross higher ground with increasingly broad ocean views. At one high point, coastline was visible on both sides of Catalina, with the California mainland in the distance under clear skies. Bison appeared along this part of the trip, though I would confirm precise encounter locations against photos or GPS data before attaching them to a specific waypoint.
The descent toward the west coast reveals Little Harbor and its surrounding slopes. The approach immediately feels more scenic than Blackjack, and the beach setting changes the rhythm of the trip.
Airport in the Sky
The airport was an unexpectedly enjoyable Day 2 stop. I ate a surprisingly good burger—hiking hunger certainly helped, but it genuinely felt like a strong meal—and watched small aircraft land and take off.
Restaurant check: The Conservancy currently lists the restaurant as open daily for breakfast and lunch, with its trail page listing 8:30 a.m.–4 p.m. Do not plan a meal around it without checking the current official airport information.
When a Bison Blocks the Trail
One bison stood directly on the trail where steep terrain made a close pass or direct off-trail bypass feel unsafe. We waited roughly five to ten minutes, ate snacks, and watched from a safe distance. When it did not move, we checked the map, backtracked slightly, used a nearby road as a minor detour, and rejoined the route later. The detour was preferable to forcing a close pass.
Takeaway: Do not allow an itinerary to pressure you into squeezing past a bison. Wait, retreat, or use a safe detour. Follow current official guidance rather than relying on a remembered distance.
Little Harbor Campground
Little Harbor was my favorite campsite. We selected a site close to the beach, with an easy walk onto the sand. Its west-facing position produced a strong sunset; I ate dinner from a large rock overlooking the harbor, a personal choice rather than a recommendation to scramble onto unfamiliar terrain.
Other campers were present, but the campground remained quiet and never felt crowded. The developed setting still felt peaceful and nature-focused. Potable water and toilets were available during the trip. Current official rules allow fires only in designated Little Harbor fire rings, subject to restrictions.
Amenity check: Verify Little Harbor’s current water, toilet, food-storage, and fire status before departure.
Day 3: Little Harbor to Parsons Landing via Two Harbors
Two major climbs and descents make the Two Harbors resupply day the itinerary’s defining physical test—12.06 mi, +3,540 ft / -3,518 ft.
Route
This was the longest and most strenuous day: up, down, up, and down again. Climb substantially away from Little Harbor, then descend toward Two Harbors. The route gives up much of that elevation at town and requires another major climb almost immediately after leaving, which makes the profile harder than the mileage alone suggests.
After passing the west side of the harbor, climb steeply through alternating dirt trail and road sections. We saw additional bison in the island’s open interior before the final steep descent toward Parsons Landing. We arrived before dark, tired and ready to stop on the beach.
Two Harbors Stop
I expected a restaurant meal, but the restaurants were closed during the January off-season. The general store was open, so we bought microwaveable burritos and snacks, used its microwave, and refilled water from a developed source. Two Harbors still provided food and water, but January options were much more limited than expected. The disappointment came from failing to check seasonal hours, not from the town itself.
Planning note: Carry enough food to remain independent of restaurant service. TODO: verify current restaurant, general-store, and developed-water operating details for the trip dates.
Sun Exposure
Day 3 included long exposed mileage. January temperatures felt comfortable, but the UV exposure remained strong. I wore shorts and did not apply enough sunscreen, leaving my legs—and likely parts of my face—sunburned. A sun hoodie, hat, sunglasses, and sunscreen matter even in winter. Starting earlier would also reduce time spent climbing under the strongest midday sun.
Parsons Landing
Parsons Landing was the most memorable overnight. The site was on or directly beside the beach, with a peaceful evening after the long day, very little light pollution, clear stars, and waves audible throughout the night. Cowboy camping here was a trip highlight. The following morning brought a beach sunrise; the January ocean was too cold to make swimming appealing, though putting sore feet in the water and sand still felt good.
There was no normal potable-water spigot for us to use. Water, firewood, and a fire starter had been arranged before arrival and were waiting in the campsite area. The official camping page currently describes a pre-purchased Parsons Landing locker with water and fire supplies, but the ordering and access process is changeable. Fire restrictions can override normal arrangements.
Critical water note: Parsons Landing requires advance water planning. Do not hike there assuming a normal campground spigot will be available. Verify the current process, quantity, access method, price, fire rules, toilet, and food-storage situation on the official camping page. TODO: confirm all details immediately before publication.
Day 4: Parsons Landing to Two Harbors
A rolling coastal-road return trades the earlier ridge drama for a practical finish at the ferry—7.60 mi, +551 ft / -573 ft.
Route
Begin with sunrise at Parsons Landing, then leave the beach and return toward Two Harbors. This final section involved substantial road walking and was nearly even in total gain and loss, with several short rollers rather than a sustained downhill trend. Compared with the earlier days, it felt less scenic and more like a walk back to transportation.
My feet were sore after Day 3, and the ferry departure created a firm time objective. By that point, it felt more like a practical walk back to the ferry than a major scenic climax. Finish in Two Harbors, use the town’s basic services if open, and board the ferry to San Pedro. Verify the sailing before setting the day’s pace.
Water Strategy
Treat Catalina as a dry route and plan each day around confirmed developed sources rather than natural water.
We relied entirely on developed campground and town water and did not filter any natural sources. No streams or reliable wild sources were used. Reservoirs we saw during this unusually dry period appeared extremely low or dry. Leave every confirmed source with enough water to reach the next one, refill whenever reliable water is available, and arrange Parsons Landing water in advance.
The official camping page currently lists potable water at island campgrounds except Parsons Landing, but systems can fail, be shut off, or become unavailable. Verify water status shortly before departure and never assume a map symbol guarantees water. The author does not remember an exact carrying capacity, so this guide does not prescribe one.
Bison and Wildlife
Wildlife encounters were memorable, but bison required the most consequential on-trail decisions.
Bison
Seeing bison was a trip highlight, but maintaining distance mattered more than preserving the exact route line.
We saw multiple bison. One passed relatively close to the trail; I gave it as wide a berth as the terrain allowed while it calmly continued grazing. A separate animal blocked the trail entirely, leading to the road detour described on Day 2. The bison were among the most memorable parts of the trip and also its most consequential safety concern.
Do not approach for photos, squeeze past, yell at, or provoke bison. Wait, retreat, or detour, prioritizing distance over remaining exactly on the planned track. Roads may offer alternatives in some places, but never assume a detour exists. The Conservancy advises giving bison a path to avoid you and, where possible, placing a large object such as a tree, rock, or vehicle between you and the animal. Review the current official Trans-Catalina Trail guidance before hiking.
Island Fox and Food Storage
The island fox encounter was brief; the practical takeaway is to keep every camp secure from small, persistent wildlife.
An island fox appeared near the trail, likely during the final day. It paused in the brush and watched us; I took a quick photo and continued. Do not feed or approach foxes. Use the provided food-storage facilities where available and keep food secured from foxes, ravens, and rodents.
Food-storage check: Verify the exact current storage facilities at Blackjack, Little Harbor, and Parsons Landing before departure.
Seasonal Considerations
January reduced heat and crowds, while shorter daylight and reduced services demanded closer planning.
Mid-January brought comfortable daytime temperatures, mild nights, quieter campgrounds, clear skies, and excellent stargazing. The lack of oppressive heat made the exposed climbs more manageable, and the weather suited cowboy camping. Winter also meant shorter daylight, cold ocean water, reduced restaurant service, and ferry schedules that required close checking.
This trip occurred during an unusually dry period. No rain fell, and reservoirs appeared very low or dry. Those conditions made hiking and sleeping outside easier, but drought is not environmentally positive and should not be romanticized. A future January trip may bring rain, wind, colder nights, or rougher ferry conditions.
I would personally avoid peak summer because heat, exposed climbing, stronger sun, and greater water demand would reduce my enjoyment. That is a preference rather than a claim that summer is universally unsafe. For hikers who dislike heat, cooler months may be more pleasant, but winter ferry schedules, campground operations, rain, and restaurant hours require closer verification.
Cowboy Camping
Clear January skies made sleeping outside memorable, especially beside the waves at Parsons Landing.
I cowboy camped all three nights, sleeping on a pad outside the tent and placing it over the rainfly or another protective layer to reduce puncture risk. I carried a Big Agnes Copper Spur but never needed to pitch it fully. Parsons Landing was the best night: clear stars and the sound of the ocean made the simple setup particularly memorable.
Carry a shelter as backup, use a reliable forecast, secure food, and expect sand and dirt on equipment. Conditions can change quickly; one dry trip is not a reason to leave shelter at home.
Four Days or Five Days?
Four days keeps both beach camps while concentrating the route’s hardest climbing into one demanding day.
Three days is possible for strong hikers, but it would require significantly more mileage, feel rushed, and reduce time at the beaches and camps. It would not be my preferred experience.
Four days was the sweet spot for me. It creates one major grind day but leaves enough time to enjoy both Little Harbor and Parsons Landing, maintains momentum, and avoids stretching the route unnecessarily. I recommend it for fit backpackers.
Five days adds a night at Two Harbors and breaks up the difficult third day. That pace may be better for newer backpackers or anyone with abundant time, though experienced hikers may find it slower than necessary. If I hiked the trail again, I would still choose four days. With unlimited time, five would be enjoyable, but four struck the best balance between challenge and relaxation.
Practical Gear and Safety Notes
Sun protection, water capacity, and secure footing matter more here than technical mountain equipment.
A trekking pole or poles, sun hoodie, hat, sunglasses, sunscreen, grippy footwear, suitable water capacity, a warm sleeping layer, shelter, backup toilet paper, and disciplined food storage cover the most route-specific needs. I used one trekking pole and valued it most on steep descents. I prefer boots, though trail runners would be reasonable because the terrain was not technically extreme.
A 30- or 40-degree sleeping bag was adequate during this specific trip, but future conditions may require more insulation. I carried rain gear despite not using it. No special beach stakes were needed because I never fully pitched the tent, and sand shook out of the gear easily.
The main concerns are bison, sun exposure, dehydration, steep or loose dirt, long mileage, ferry and campground logistics, and weather or wind. There was no major cliff exposure, and the trail did not feel technically dangerous, though a misstep on a loose descent could cause a slide or ankle injury. Developed infrastructure lowers the consequences compared with a remote wilderness route; it does not eliminate the need for planning.
This trek best suits fit hikers seeking an accessible multi-day trip, newer backpackers accompanied by someone experienced, travelers who want a destination route without a rental car, and experienced backpackers willing to trade deep wilderness for beaches and ocean views. It may disappoint hikers seeking wild camping, complete solitude, minimal road walking, flexible camps, or guaranteed restaurant meals.
Is This Worth Backpacking?
The trail trades deep wilderness for approachable logistics without giving up scenery or physical challenge.
Yes, absolutely. This route ranks highly among my trips. Seeing ocean on both sides of the island was a major scenic highlight; bison and the island fox made it memorable; Little Harbor and Parsons Landing were excellent camps; and Airport in the Sky was an unexpectedly fun stop. The route felt physically rewarding without becoming technically extreme.
It is less wild than the Pemi Loop, Superstition Wilderness, Jotunheimen, or Mont Aorai, but that does not make it inferior. It serves a different purpose. The Trans-Catalina Trail is a scenic, accessible backpacking trip that removes many logistical barriers without removing the physical challenge. It is not deep wilderness, but its ocean views, wildlife, beach camps, and island setting make it memorable on its own terms.
What I Would Do Differently
The itinerary worked; the main improvements involve sun protection, an earlier Day 3 start, and tighter service checks.
- Apply and reapply more sunscreen, especially on exposed legs while wearing shorts.
- Start Day 3 somewhat earlier to reduce time under the strongest sun.
- Verify Two Harbors restaurant and store hours and carry food that does not depend on town service.
- Confirm every campground’s water status and the Parsons Landing supply arrangement before departure.
- Keep the Avalon-to-Two-Harbors direction and the four-day itinerary.
- Choose five days only for a deliberately more leisurely trip.
