Do You Need a Permit? A Complete Guide to Backcountry Permits

Everything backpackers need to know about wilderness permits — which trails require them, how to get them, and tips for navigating lottery systems.

One of the most common questions new backpackers ask is: "Do I need a permit?" The answer depends entirely on where you're going. This guide breaks down the permit landscape across the US so you can plan ahead and avoid surprises at the trailhead.

Types of Backcountry Permits

Self-Registration (Free)

Many wilderness areas have simple self-registration systems at the trailhead. You fill out a card with your name, group size, and itinerary, then drop it in a box. These are free and don't require advance planning.

Examples: Most National Forest wilderness areas, Lost Creek Wilderness (CO), Pecos Wilderness (NM)

Quota-Based Permits

Some popular areas limit the number of overnight visitors per day. You'll need to reserve a permit in advance, often months ahead. These may be free or have a small fee.

Examples: Enchantments (WA) — requires lottery, Yosemite Wilderness, Grand Canyon backcountry

Lottery Permits

The most competitive permits use a lottery system. You apply during a specific window months before your trip, and a random drawing determines who gets a permit.

Examples: Enchantments (WA), Half Dome day permits, Havasu Falls (AZ)

Walk-Up Permits

Some permit systems hold a portion of permits for walk-up (day-of) visitors. This can be a good option if you're flexible with dates or willing to try your luck.

Examples: Many National Park wilderness permits, including portions of Yosemite and Grand Teton

Permits by Land Manager

National Parks (NPS)

Most National Parks require backcountry permits for overnight trips. Systems vary widely — some are first-come, first-served, while others require advance reservations. Fees typically range from free to $30.

National Forests (USFS)

Most National Forest wilderness areas have free self-registration. Notable exceptions include the Enchantments, Mt. Whitney Zone, and some areas in the Pacific Northwest that require Northwest Forest Passes.

Bureau of Land Management (BLM)

BLM lands generally don't require permits for backcountry camping. Exceptions exist for specific recreation areas.

State Parks

Policies vary by state. Some require permits, some require campsite reservations, and some are open-access.

Tips for Getting Competitive Permits

  1. Know the application window. Most lottery systems open 6 months before the season. Mark your calendar.
  2. Be flexible with dates. Midweek trips and shoulder-season dates are less competitive.
  3. Have a backup plan. If you don't get your first choice, have alternative trails ready.
  4. Check for cancellations. Popular permit systems often have cancellations, especially as the season approaches. Check recreation.gov regularly.
  5. Consider less popular trailheads. Many wilderness areas have multiple entry points. The less popular ones may have permits available when the main trailhead is full.
