The US National Park Service maintains restroom facilities at hundreds of parks across the country, ranging from high-traffic urban parks to remote wilderness areas. Knowing what to expect — and how to prepare — makes for a better visit.

Types of National Park Restrooms

The NPS uses several types of facilities depending on location and usage:

  • Flush toilet comfort stations: Found at visitor centers, major campgrounds and heavily trafficked areas. Generally the cleanest and best-maintained option.
  • Vault toilets: The most common type in backcountry and lower-traffic areas. Non-flushing, but NPS maintains them on a service schedule. They lack running water, so carry hand sanitizer.
  • Pit toilets: Basic, self-contained units in very remote areas. Some are seasonal only.
  • Portable units: Often placed temporarily for special events or trail work seasons.

Visitor Centers

Every national park visitor center has flush toilet facilities. These are your best option for cleanliness and accessibility. Plan your visit to include a stop at the visitor center near the start or end of your day.

Campground Facilities

Developed NPS campgrounds have restroom facilities ranging from vault toilets to full shower and flush-toilet comfort stations. Reservations.gov lists the facility type for each campground when booking.

Tip: For popular parks like Yellowstone, Yosemite and Grand Canyon, look up the NPS park website's "fees and passes" or "visitor information" section for a restroom location map before you go.

Accessibility in National Parks

The NPS has made extensive ADA improvements across its system. Visitor center restrooms are almost universally accessible. Many backcountry vault toilet facilities also meet accessibility standards. The NPS Access Pass (free for permanent disabilities) can unlock additional facilities.

Leave No Trace: Backcountry Sanitation

When no restroom is available in backcountry areas, Leave No Trace principles require: burying human waste in a cathole 6–8 inches deep and 200 feet from water, trails and camp. Pack out all toilet paper in a waste bag. Many parks in sensitive environments require a wag bag (portable waste containment) instead.

Tips for Popular Parks

At Yellowstone, Grand Canyon, Zion and other high-traffic parks, restroom lines during peak season (summer) can be long. Visit facilities at less-obvious locations along park roads rather than just at the most popular overlooks.
