The Pacific Crest Trail: A Complete Guide to Hiking the PCT

The Pacific Crest Trail runs 2,650 miles from the Mexican border in Southern California to the Canadian border in Washington, crossing desert, the High Sierra, and the volcanic Cascades — and it’s the thru-hike most people picture when they imagine long-distance backpacking, thanks in no small part to Wild. Here’s what actually matters if you’re considering it.

Quick Stats

The Permit Lottery

The PCT uses a long-distance permit system issued through the Pacific Crest Trail Association, with a limited number of daily start-date slots released during a competitive application window. This is the first real logistics hurdle for anyone planning a thru-hike — popular spring start dates (especially early-to-mid April) fill fast, and getting your preferred date isn’t guaranteed. Apply the moment the application window opens, and have backup start dates in mind.

Best Season: The Desert-to-Sierra-to-Cascades Timing Puzzle

The PCT’s core planning challenge is a three-part timing puzzle:

1. Southern California desert (miles 0-700ish): hot, dry, with real water-carrying logistics between sparse sources. Starting too early means cold desert nights; starting too late means brutal heat.
2. The High Sierra (roughly miles 700-1000): the trail’s most dangerous section in high-snow years. NOBO hikers typically arrive in June, when several 11,000-13,000 ft passes (Forester, Glen, Mather, Pinchot) can still hold significant snowpack, requiring an ice axe, microspikes, and real snow-travel judgment. Check that year’s Sierra snowpack data before your entry date — this is essential planning, not a nice-to-have. Some hikers “flip-flop” (skip ahead to Oregon/Washington and return to the Sierra later in the season) specifically to avoid a dangerous early-season crossing.
3. Washington’s North Cascades (the finish): early snow can close the trail’s northern terminus as early as late September, so NOBO hikers need to budget their pace to finish before winter arrives up north.

Get these three timing windows right and the PCT is a manageable, if long, undertaking. Get them wrong and you’re facing real avalanche or hypothermia risk.

Resupply Strategy

The PCT is well-served by an established hiker-resupply culture — most trail towns near the route are used to thru-hikers and have post offices set up for mail-drops, plus outfitters that stock trail-specific gear and food. Resupply intervals average 3-5 days between towns, shorter than the CDT’s longer stretches. Many hikers use a hybrid strategy: buy as you go in towns with good grocery options, and mail specialized food or gear (bear canister-compatible meals for the Sierra, cold-weather gear for Washington) ahead to more remote stops.

Gear Considerations Specific to the PCT

• Bear canister required in the Sierra section (Yosemite, Sequoia/Kings Canyon, and surrounding wilderness areas legally mandate one) — see our Best Bear Canisters guide and factor its bulk into your pack sizing.
• Serious water-carrying capacity for the desert section — some SoCal stretches require carrying 4-6+ liters between sources. See How Much Water to Carry.
• Microspikes and an ice axe for Sierra snow years — check current-season snowpack reports before committing to skip these; conditions vary enormously year to year.
• A genuinely reliable rain shell for Washington — the North Cascades see real, sustained rain, especially in a late-season finish. See our Best Rain Jackets guide.
• Sun protection for the desert — long stretches with zero shade make a sun hoodie and good sunglasses non-negotiable, not optional comfort items.

Iconic Sections

• The High Sierra — Forester Pass (the trail’s highest point), the John Muir Trail overlap, and some of the most photographed alpine terrain in North America. Our John Muir Trail section trip report covers an overlapping stretch.
• Crater Lake, Oregon — the trail passes directly by one of the most striking bodies of water in the National Park System.
• The Goat Rocks Wilderness, Washington — a knife-edge ridge walk widely considered one of the PCT’s most spectacular (and exposed) stretches.
• Half Dome side trip, Yosemite — many PCT hikers detour for it; see our Half Dome guide if you’re considering the same.

Who It’s For

The PCT is a strong choice for a first thru-hike for hikers who are comfortable with real physical demands and want a well-established trail culture, resupply infrastructure, and (mostly) well-graded, consistent tread — in exchange for real desert and Sierra-snow logistics to plan around carefully.

Getting Started

1. Apply for your permit the day the window opens — this is the first real deadline in PCT planning.
2. Dial in your gear — see our Backpacking Gear Checklist and How to Pack a 10-Pound Base Weight.
3. Train for sustained daily mileage — see How to Train for a Multi-Day Hike.
4. Research that year’s Sierra snowpack as your start date approaches — conditions vary dramatically year to year and directly affect your safety through the High Sierra.

Bottom Line

The PCT rewards careful timing more than raw toughness — get the desert, Sierra snow, and Washington-finish windows right, lean on the trail’s excellent resupply infrastructure, and you have one of the most scenic, well-supported long-distance hikes in the world.
