Essential Travel Tips for USA National Parks

Planning a national park trip requires forward preparation. Keep these essential travel guidelines in mind:

1. Timed-Entry Reservations & Permits

To manage high visitation and preserve wilderness environments, several popular national parks require advance reservations or timed-entry permits during peak season:

• Zion: Permits are required year-round via lottery for the chain section of Angels Landing.
• Rocky Mountain: Timed-entry reservations are required from late May through October for the Bear Lake Road corridor and general park access.
• Glacier: Vehicle reservations are required during summer for key corridors, including the Going-to-the-Sun Road and Many Glacier entrance.
• Acadia: Vehicle reservations are required to drive up Cadillac Mountain during peak season.
• Yosemite: Check park updates for peak-hours reservation requirements during summer weekends and holidays.

2. Purchase an “America the Beautiful” Interagency Pass

If you plan to visit three or more national parks within 12 months, buy the America the Beautiful Pass. Costing $80 annually, this pass covers entrance fees for the pass holder and all passengers in a single private vehicle at over 2,000 federal recreation sites nationwide.

3. Practice “Leave No Trace” & Wildlife Safety

• Keep Wildlife Wild: Always maintain a safe distance from wildlife stay at least 100 yards (91 meters) away from bears and wolves, and 25 yards (23 meters) away from all other wildlife, including bison, elk, and moose.
• Bear Safety: Carry bear spray in an easily accessible holster (not inside your backpack) when hiking in grizzly country (Yellowstone, Teton, Glacier). Know how to use it!
• Pack It In, Pack It Out: Dispose of all trash properly, stay on designated trails to prevent soil erosion, and never remove natural objects or rocks from national parks.

4. Book Accommodations Months in Advance

Lodging and campsites inside national parks (such as historic lodges like the Old Faithful Inn or El Tovar) often open reservations 12 months in advance and sell out within minutes. Plan early or look for accommodations in gateway towns outside park entrances.
