Best Time to Hike the Pacific Crest Trail 2026: Month-by-Month Start Guide

The best time to start a northbound Pacific Crest Trail thru-hike in 2026 is between late April and mid-May. This timing lets you cross the desert before peak heat, reach the Sierra Nevada once the worst of the snow has gone, and finish in Washington before autumn snow returns to the North Cascades.

Timing the 4,265 km Pacific Crest Trail is the single biggest planning decision you will make. Start too early and you hit the Sierra under deep snow; start too late and Washington's autumn storms catch you short of Canada. Here is how the season breaks down for 2026.

When should you start the PCT northbound in 2026?

Most northbound hikers begin at Campo on the Mexican border in late April or early May. This window balances three constraints: desert heat that builds into summer, Sierra snowpack that needs to consolidate, and a finish at the Canadian border before the North Cascades turn wintry. As Wikipedia puts it, the timing is a balance between not getting to the Sierra too soon nor the Northern Cascades too late. Long-distance permits for northbound starts are limited to 50 per day in March, April and May, so hikers spread across this window rather than bunching at one date.

Spring: the desert section (April to May)

The first roughly 1,100 km, to Kennedy Meadows, cross Southern California's deserts, where daytime heat is high and water sources are far apart. Start in late April and you walk in cooler mornings, hiking early and resting through the afternoon. A well-ventilated pack such as the Hyperlite Mountain Gear 2400 Windrider keeps your back cooler on long water carries. Carry enough water capacity for the longest dry stretches. Our Pacific Crest Trail packing list covers the desert water-carry setup in detail.

Early summer: the Sierra Nevada (June)

The High Sierra is the crux of PCT timing. Entering the Sierra at Kennedy Meadows in June means crossing Forester Pass (4,009 m), the highest point on the trail, and Glen Pass on consolidating snow that holds an axe and microspikes well in the morning. Go too early, in a heavy snow year, and creek fords swollen with melt become the real danger. A pack that carries a bear canister and extra food cleanly, like the Zpacks Arc Blast 55L, earns its place here.

Late summer: Northern California and Oregon (July to August)

From the Sierra north, the trail mellows. Oregon's gentle grades let hikers post long days. Wildfire smoke is the main variable: summer fires can close sections, so track closures through the PCTA. Milder temperatures and more water make this a more relaxed stretch. A comfortable suspended pack such as the Osprey Atmos AG 65 suits hikers carrying a heavier kit through this phase.

Autumn: Washington and the finish (September)

Washington's North Cascades demand a finish before the first serious storms, usually by mid-to-late September. The Washington stretch holds sustained climbs and fickle weather, with early snow possible on the high passes. Hikers who entered the Sierra on time reach the northern terminus at the Canada–US border before the season closes. Note that you can no longer walk on into Manning Park: the Canada PCT entry permit was discontinued as of January 31, 2025, so plan your exit from the border back on the US side. Late starters or slow seasons face a real risk of being snowed off the final passes.

What about a southbound (SOBO) hike?

Southbound hikers start at the Canadian border once Washington's snow clears, and finish in the desert in autumn. SOBO suits experienced hikers comfortable with early-season snow and smaller trail crowds. It is harder logistically — the toughest terrain comes first while your body is still adapting — but it dodges the northbound crowd at the southern terminus.

How a heavy snow year changes your start date

Snowpack is the variable that can override the calendar. In a heavy snow year, the High Sierra holds dangerous conditions weeks longer, swelling creek fords with meltwater and burying the tread above 3,000 m into July. Hikers respond in three ways: starting later in May so the snow consolidates, slowing their pace to let the Sierra melt out, or flip-flopping north to hike Northern California and Oregon first before returning to the Sierra. The California snow survey, published through the season, is the figure to watch: a high snowpack is the signal to delay or flip. Hikers who later move to the higher, snowier Continental Divide Trail face the same calculus on Colorado's passes, which hold snow even deeper into summer. Build flexibility into your 2026 itinerary rather than locking every resupply box to a fixed date, and carry an ice axe and microspikes through the Sierra regardless of the forecast. A well-fitted load-hauling pack such as the supportive Osprey Atmos AG 65 makes the heavier early-season Sierra carries safer on snow, where every extra kilo is harder to manage on an exposed traverse.

Frequently Asked Questions

What month should I start the PCT in 2026?

Start the Pacific Crest Trail northbound between late April and mid-May 2026. This lets you clear the desert before peak heat, reach the Sierra Nevada around June 15 once snow consolidates, and finish Washington before mid-September storms. The PCTA assigns staggered permit start dates within this window to manage crowding.

How much snow will be in the Sierra in 2026?

The 2026 Sierra snowpack is forecast to be normal to slightly above average, meaning passes like the 4,009 m Forester Pass should melt out by early July. Hikers entering Kennedy Meadows around June 10 to 18 will likely cross consolidated snow in the mornings. Always check the latest snow survey data before committing to your start date.

Can you hike the PCT in winter?

No. The Pacific Crest Trail is not a winter route. The Sierra Nevada and North Cascades hold deep snow from October through May, with avalanche risk and buried tread. The hiking season runs roughly late April to late September for a northbound thru-hike, and June to November for southbound.

Is the PCT desert section dangerous in summer?

The desert section is manageable in spring but dangerous by mid-summer, when highs exceed 38 C and water sources sit 25 to 40 km apart. Hikers starting in late April avoid the worst heat by walking in cool mornings and resting through the afternoon. Carrying capacity for 5 to 6 litres of water is the key safety margin.

How long is the PCT hiking window?

The northbound PCT window is about five months, from a late-April start to a mid-September Canadian finish, covering 4,265 km. Most hikers average 25 to 40 km per day. Missing the window risks being caught by Sierra creek floods early or North Cascades snow late, both of which can end a hike.
