Rangers are on duty at most entry points to collect fees, issue backcountry permits, and answer questions.
Fees--Admission to the park for up to 7 days costs $10 per vehicle or $5 per person for those on foot, bicycles, and motorcycles. A season pass costs $20 and allows unlimited entry to Glacier National Park for 1 year. The National Park, Golden Eagle, Golden Age, and Golden Access passes are also honored. Camping fees are $12 to $17 per night at the park's drive-in campgrounds. A separate entrance fee is charged for visitors to Waterton Lakes National Park.
Backcountry Permits--These permits must be obtained in person from the Apgar Backcountry Permitting Station, St. Mary Visitor Center, or the ranger stations at Many Glacier, Polebridge, or Two Medicine. Visitors who enter Glacier's backcountry from the Canadian side (at Goat Haunt or Belly River in Waterton) can get a permit at the Waterton Visitor Reception Centre, but only with a credit card. During summer months, permits may be obtained no earlier than 24 hours before your trip. There is a $4 per-person per-night charge for backcountry camping. Trips are limited to 6 nights, with no more than 3 nights allowed at each campground (some exceptions apply). Campsites are limited. A single site has a maximum occupancy of four persons. Stoves are required in most areas (no open fires) and pets are not permitted on the trails.
To ensure a spot and avoid the hassle, order an Advance Reservation Backcountry Trip planner from Backcountry Reservations, GNP, West Glacier, MT 59936; sending them your dates with a check for $20 will reserve your spot in the wilderness.
Due to lower demand in winter, camping permits are available up to 7 days in advance. A few rules do take effect beginning each November 20, so double-check at visitor centers for details.
