PCT San Diego to Cascade Locks: Miles & Logistics

From San Diego International Airport it is roughly 60 miles by road to the Pacific Crest Trail's southern terminus at Campo, and from there the trail covers about 2,147 miles (3,455 km) north to Cascade Locks, Oregon, where it crosses the Columbia River on the Bridge of the Gods. Most hikers walk that stretch in three to four months.

Cascade Locks is not a random waypoint — it is the psychological halfway-feeling marker where the PCT leaves Oregon and enters Washington, and the lowest point on the entire trail at around 150 feet (46 m) of elevation. Plenty of searchers want to know exactly how far they will walk between the desert start near San Diego and that Columbia River crossing, and how to physically get to the trailhead in the first place. This guide answers both.

How far is it from San Diego to Cascade Locks on the PCT?

The walking distance from the Campo southern terminus to Cascade Locks is approximately 2,147 trail miles (3,455 km) — about 81% of the full 2,650-mile (4,265 km) Pacific Crest Trail. San Diego itself sits off-trail; the airport is your gateway, and the terminus is a 60-mile (97 km) road transfer southeast to the Mexican border fence at Campo.

If you want to convert those segment distances into realistic daily mileage and finishing dates for your own pace, plug them into our hiking time calculator — a 22 mile/day average covers the Campo–Cascade Locks stretch in roughly 98 walking days before zeros.

How do you get from San Diego International Airport to the Campo trailhead?

San Diego International Airport (SAN) is the closest major airport to the southern terminus, and the 60-mile transfer to Campo is the first logistics puzzle of any northbound thru-hike. As of 2026 there are four reliable options:

1. Trail-angel ride — the long tradition of San Diego hosts shuttling hikers to Campo continues, now coordinated largely through the Pacific Crest Trail Association community rather than a single household. Confirm arrangements before you fly; do not assume a free ride will appear.
2. Public transit — from downtown you can chain the MTS trolley with rural Route 894, which serves Campo on limited weekdays. It is cheap (under $10) but slow and inflexible, so check the live timetable.
3. Rideshare or taxi — an Uber or Lyft from SAN to Campo runs roughly $90–130 and takes about 1.5 hours. Coverage thins near the border, so book the return leg is not guaranteed.
4. Rental car drop-off — practical if two or three hikers split it, but there is no one-way drop near Campo, so someone has to drive back.

Spend at least one night in San Diego to assemble fuel and food you could not fly with; the city is your last full-service resupply before the desert.

What does the walk north to Cascade Locks actually involve?

The 2,147 miles break into four very different worlds. The Southern California desert (miles 0–700) is less flat sand than a series of dry mountain ranges, with water carries of 15–30 miles and afternoon heat that pushes most hikers to walk at dawn and dusk. The Sierra Nevada (miles 700–1,090) is the high, glaciated heart: Forester Pass tops out at 13,153 feet (4,009 m), and snow timing dictates everything.

Northern California (miles 1,090–1,690) is the long, underrated middle — lava fields, Burney Falls and the climb around Mount Shasta — where many hikers either find their rhythm or quit. Finally, Oregon (miles 1,690–2,147) is graded gently enough that some hikers attempt the “Oregon Challenge” of 455 miles in under two weeks before the trail drops to the Columbia.

Around Cascade Locks the Columbia River Gorge offers some of the best side-trail hiking on the route. The Eagle Creek Trail is a celebrated alternate that passes Tunnel Falls just east of town, and across the river the steep wildflower climb of the Dog Mountain trails rewards a rest day. South of the Gorge, the PCT itself wraps Mount Hood, where the loop-hiking Mt. Hood Timberline Trail shares tread with the thru-route and Timberline Lodge serves its legendary breakfast buffet.

When should you start, and how long does it take?

Northbound hikers leave Campo between mid-April and mid-May to balance desert heat against Sierra snow. A start around 1 May 2026 typically puts a steady hiker at Cascade Locks in early to mid-August, leaving enough margin to finish Washington before October storms. The Bridge of the Gods crossing into Washington charges pedestrians a small toll (historically $0.50), and there is no walkway — you share the narrow deck with cars, so cross with care.

Reaching Cascade Locks at all requires the right permit: the PCTA issues a long-distance permit for trips of 500 continuous miles or more, and the 2026 quota releases open in two waves during the previous autumn and winter. Plan permit timing before you book flights.

What gear survives 2,100 miles of trail?

The defining gear decision for this distance is the pack, because it must carry a bear canister through the Sierra and long desert water loads while staying light enough for 2,000-plus miles. Frameless and ultralight-frame packs dominate the trail: the Dyneema Hyperlite Mountain Gear 3400 Windrider handles bear-canister volume at roughly 900 g, while the Zpacks Arc Haul Ultra 60L adds a tensioned frame for ventilation in the desert heat. Hikers who prefer a traditional supportive carry for the Sierra food loads still reach for the Osprey Aether 65, heavier but rugged.

Whatever you choose, weigh the full kit before you fly. Logging every item in the base weight calculator is the single cheapest way to find the kilos you are about to carry across California.

What airport do you fly into for the PCT southern terminus?

San Diego International Airport (SAN) is the closest major airport to the Campo terminus, about 60 miles (97 km) away by road. Most hikers spend a night in San Diego, then reach Campo by trail-angel ride, MTS rural Route 894, or a rideshare costing roughly $90–130.

Why is Cascade Locks important on the PCT?

Cascade Locks is the lowest point on the entire trail at around 150 feet (46 m) and the spot where the PCT leaves Oregon for Washington via the Bridge of the Gods over the Columbia River. It is a major resupply town and a powerful milestone, with under 510 miles of trail remaining to Canada.

Do you need a permit to hike from San Diego to Cascade Locks?

Yes. Any continuous trip of 500 miles or more requires the Pacific Crest Trail Association long-distance permit, which covers the full Campo-to-Cascade-Locks distance. Quota spaces for 2026 are released in two waves during the preceding autumn and winter, so secure the permit before booking flights.

For official mileage, permit dates and current trail conditions, consult the Pacific Crest Trail Association, and check live schedules for the Campo transfer on the San Diego Metropolitan Transit System.
