Pacific Crest Trail: Routes, Sections, and Planning

The Pacific Crest Trail spans 2,653 miles from the Mexican border at Campo, California to the Canadian border near Manning Provincial Park in British Columbia — making it one of the longest continuous footpaths in the United States. This page covers the trail's structure by section, the logistical machinery behind a thru-hike or section hike, the permit system, and the planning decisions that distinguish a successful passage from a premature one.

Definition and scope

The PCT is a National Scenic Trail administered jointly by the Pacific Crest Trail Association (PCTA) and the USDA Forest Service. Congress designated it under the National Trails System Act of 1968 — the same legislation that created the Appalachian Trail's federal framework. The trail passes through 3 states (California, Oregon, and Washington), 25 national forests, and 7 national parks. Its southern terminus sits at 2,915 feet elevation at the Campo port of entry monument; its northern terminus near the 4,245-foot Monument 78 on the US-Canada boundary.

The trail's 2,653-mile figure is not arbitrary trail-counter math — it's the PCTA's official measured distance as of its most recent route certification, accounting for alternate routes that have become standard due to fire, snow closures, or infrastructure changes. That number shifts slightly when the PCTA reroutes segments, which happens with some regularity in high-fire years. Exploring the broader landscape of long-distance hiking trails in the US puts the PCT's scale in context: only the Continental Divide Trail (roughly 3,100 miles) exceeds it in length among American long trails.

Core mechanics or structure

The PCT divides into three broad geographic regions, each with distinct ecological and logistical character.

California (1,702 miles) constitutes nearly two-thirds of the entire trail. It runs from the Sonoran Desert scrub near Campo through the San Jacinto Mountains (summit elevation 10,834 feet), across the Mojave Desert, through the High Sierra Nevada, and north through volcanic terrain in the Cascades to the Oregon border near Seiad Valley. The Sierra Nevada segment — roughly miles 700 through 1,100 — includes 13 passes above 11,000 feet, with Forester Pass at 13,153 feet as the highest point on the entire trail.

Oregon (455 miles) is often described by experienced hikers as the trail's most forgiving stretch. Elevation changes are moderate compared to the Sierra, resupply towns appear at reasonable intervals, and trail conditions tend to be less technically demanding. Crater Lake National Park sits at roughly the Oregon midpoint, at an elevation of 7,173 feet at the crater rim.

Washington (497 miles) closes the route with some of its most dramatic terrain. The North Cascades are among the most glaciated mountains in the contiguous United States, and the final 70 miles through the Pasayten Wilderness demand precise timing — snow closes the northern terminus region as early as mid-October in poor weather years.

Causal relationships or drivers

Permit demand on the PCT is directly shaped by the PCTA's Long-Distance Permit system, introduced in 2011 and restructured in subsequent years. As of the PCTA's permit portal, a limited number of thru-hike permits are issued per day by start date at the southern and northern termini. The daily quota at the southern terminus (Campo) caps entry at 50 people per day. This cap exists because the southern terminus corridor — particularly the first 700 miles through the desert and into the Sierra — cannot absorb unlimited foot traffic without measurable trail degradation, water source contamination, and campsite erosion.

Permit lottery windows drive start date clustering. The majority of southbound (SOBO) and northbound (NOBO) thru-hikers attempt to begin between late April and mid-May from the south, and late June from the north, creating a predictable density wave that moves up the trail through the summer. That density wave is not uniform: it compresses dramatically at resupply bottlenecks like Kennedy Meadows (mile 702), where hikers transition from desert gear to Sierra gear, and at Cascade Locks, Oregon (mile 2,147), the iconic bridge crossing into Washington.

Hiking permits and regulations covering the PCT extend beyond the terminus quota — the John Muir Trail overlap zone in the High Sierra requires separate overnight permits through the Inyo National Forest and other managing agencies.

Classification boundaries

The PCT accommodates three fundamentally different engagement modes, each with distinct planning profiles:

Thru-hiking involves completing all 2,653 miles in a single continuous direction within one calendar season (typically 4 to 6 months NOBO, or 3.5 to 5 months SOBO). The PCTA defines a thru-hike as completing the full trail distance with no more than the standard permitted breaks.

Section hiking means completing the trail in segments over multiple years or seasons. The PCTA counts section hikers among its long-distance permit recipients and has published a Section Hiking Guide covering all 30 official sections.

Day hiking and overnight trips on PCT segments require no PCT-specific permit at most trailheads, though the managing land unit's regulations apply — wilderness permits for overnight stays in designated wilderness areas are required and issued independently by each national forest or park.

The distinction between a legitimate thru-hike and a "flip-flop" (starting in the middle, going north, then returning to the midpoint and going south) sits in contested territory within the hiking community — the PCTA accepts flip-flop completions for its completion certificate program.

Tradeoffs and tensions

The PCT's permit system creates a genuine tension between access equity and ecological preservation. The 50-person-per-day cap at Campo is low enough to limit crowding in the desert corridor but high enough that popular start dates sell out within hours of the permit window opening — a dynamic that disadvantages hikers without flexible schedules or reliable internet access on the opening day.

Water sourcing in California's desert section (roughly miles 0 through 700) depends almost entirely on a volunteer-maintained cache network coordinated by the PCTA's trail angels and water report system. In drought years, multiple caches between Scissors Crossing (mile 78) and Tehachapi (mile 558) have run dry simultaneously, requiring reroutes. The trail's physical design in this section predates the water security concerns of the 21st century — a design-reality gap that no permit system resolves.

Snow timing in the High Sierra creates a hard timing constraint that interacts awkwardly with the permit system. A NOBO hiker starting in late April may arrive at the Sierra Nevada in late May — before the snowpack has consolidated for safe travel. A hiker starting in late May may hit the Sierra at the right time but risk running into early fall snow in the Washington Cascades. There is no universally correct answer; seasonal hiking guidance from the PCTA and National Forest avalanche centers provides the best available forecast data.

Common misconceptions

"The PCT is always open." Federal land managers close segments annually due to wildfire, post-fire hazard (falling snags, unstable slopes), and Washington Cascades snow. The PCTA maintains a current closures page and issues emergency alternate routes — but a planned route through a closed section is not legally passable.

"The permit system guarantees a campsite." The thru-hike permit grants access to start at the terminus. It does not reserve specific campsites, guarantee water cache availability, or supersede wilderness permit requirements in areas like the Mount Whitney Zone or Olympic National Park.

"The PCT is technically easy." The trail is well-maintained by PCTA volunteers (who contribute over 100,000 hours annually according to the PCTA's volunteer program documentation), but it includes class 2 scrambling in the High Sierra, exposed ridge traverses in Washington, and river crossings without bridges in early season that have produced fatalities. Hiking safety fundamentals and wilderness navigation skills are prerequisites, not supplements, for PCT travel in the Sierra and Cascades.

"Resupply is always available in trail towns." Post offices in small trail towns have reduced hours, close for federal holidays, and occasionally hold packages past their hold period. Kennedy Meadows South (mile 702) has one general store with limited resupply. Planning hiking nutrition and food logistics with two or three contingency options per segment is standard practice among experienced long-distance hikers.

Checklist or steps

The following sequence reflects the documented planning milestones for a PCT thru-hike, drawn from the PCTA's planning resources:

1. Determine start window — NOBO start dates between April 20 and May 15 offer the best statistical balance between desert water availability and Sierra snow conditions, per PCTA historical data.
2. Apply for the Long-Distance Permit — Applications open on a rolling basis; the terminus quota at Campo is 50 people per day, and popular dates fill within hours.
3. Obtain Sierra overnight permits — For nights in the Mount Whitney Zone, Inyo National Forest designated wilderness, and other permit zones, apply through Recreation.gov.
4. Plan resupply drops — The PCTA identifies 24 primary resupply points along the trail; Kennedy Meadows South, South Lake Tahoe, Cascade Locks, and Snoqualmie Pass are the highest-capacity options.
5. Register with the PCTA — Separate from permitting, trail registration allows the PCTA to account for hikers during closures and emergencies.
6. Obtain Washington terminus entry documentation — Crossing into Canada at Monument 78 requires a permit from the PCTA and a separate border crossing arrangement with Canada Border Services Agency.
7. Review current closures — Check the PCTA closures page no earlier than 30 days before each major segment; fire conditions in California and Washington change rapidly.
8. Arrange bailout awareness — Identify road crossings and trailheads every 50 to 100 miles where early exit is possible; this is structural planning, not pessimism.
