2025 National Parks Permits and Reservations Guide
Non classifié(e), How-To's & Resources, National Parks
Don’t miss your opportunity to visit some of the most sought-after, must-see National Parks in 2025 in the United States. When visiting the top National Parks in the USA, such as Zion, Rocky Mountain, and Yosemite National Parks, it’s essential to review the reservation, entry, and permitting requirements before heading out on your trip. No matter where you’re headed, we’ve got you covered with the permitting and reservation requirements for the top 12 National Parks.
What permits do I need?
Permit requirements will vary from park to park. For instance, not all National Parks require permits. Some may require them just to enter the park, like Rocky Mountain National Park, and others may just require permits to access specific trails, like Angels Landing in Zion National Park. Permit types can include hiking permits for some popular day hikes, backcountry/wilderness permits for overnight hikes, or car reservations for entrance.
Day hiking vs. backcountry overnight camping.
Most of the time, you won’t need a permit for day hikes. For example, trails like the Mist Trail in Yosemite, Skyline Trail at Mount Rainier, and Hidden Valley Trail in Joshua Tree are accessible without permits, making them excellent options for spontaneous day trips. Just a handful of day hikes require a permit, such as the Half Dome cables in Yosemite, Angels Landing in Zion, and the Wave (not a national park, but you get the idea).
Many popular backcountry camping trails, such as the Grand Canyon Rim-to-Rim trail or the John Muir Trail, require permits, which can be difficult to secure. These permits typically go live several months in advance, often via a lottery system on Recreation.gov. For example, Grand Canyon backcountry permits open four months before the start date, while John Muir Trail permits are available 24 weeks in advance. We recommend setting a calendar reminder to apply as soon as the lottery opens.
When Do I Need a Permit?
Most day hikes do not require permits. However, some popular trails in Zion National Park and Yosemite National Park do require them.
Day Hikes That Require Permits
- Angels Landing – Zion National Park – 5 miles
- The Narrows – Zion National Park – 16 miles
- The Subway – Zion National Park – 7 miles
- Half Dome, when the cables are up – Yosemite National Park – 16 miles
Backcountry (Wilderness) Permits
Permits are required to camp overnight in the backcountry almost everywhere. The only exception is Joshua Tree National Park in Southern California, where you do not need a permit to backcountry camp.
On the other hand, there are two parks that prohibit backcountry camping. They are Cuyahoga Valley National Park and Acadia National Park.
Timed Entry or Car Reservation Systems
In an effort to control crowds, some National Parks have implemented a timed-entry system. Make sure you check to make sure you have a slot before leaving because they will NOT let you in without one, and you may not be able to enter the park at all if all of the slots are sold out.
