About Cedar Pass Campground

Overview

Surrounded by the vast, open prairie and featuring expansive views of the Badlands, Cedar Pass Campground is a great base camp from which to explore Badlands National Park. Featuring 96 sites, this seasonal campground is open from late March through mid-October, and is conveniently located within easy walking distance of Cedar Pass Lodge & Restaurant and the Ben Reifel Visitor Center.

Recreation

An evening program led by park rangers is held nightly at the Cedar Pass Amphitheater. This event runs from Memorial Day to Labor Day, beginning each evening with a half-hour educational talk about the Badlands, covering a wide array of topics that change every evening. Once the educational part of the presentation finishes, the rangers begin a guided night sky viewing program. Interesting facts and features of our night sky will be explored and pointed out for you via laser, and telescopes are often provided to view star clusters, planets, and the Milky Way.

The Amphitheater parking lot is conveniently located at the entrance to Cedar Pass Campground, in easy walking distance for most campers! For evening program start times, please see the Ben Reifel Visitor Center, Cedar Pass Lodge, or the host kiosk at the campground entrance.

Natural Features

Cedar Pass Campground is surrounded by prairie grasslands and Badlands buttes, or geologic formations. These formations contain sandstone, siltstone, mudstone, claystone, limestone, volcanic ash, and shale. The natural beauty of this landscape makes for stunning sunrises and sunsets, while low population density and minimal light pollution creates a beautiful night sky most evenings.
