Devils Tower: Rock Formation and Cultural History

Devils Tower is a geological formation that rises above the prairie surrounding the Black Hills. Hundreds of parallel cracks divide the rock into large hexagonal columns. The crystalline igneous rock is classified as phonolite porphyry. This combination of a striking shape and clearly visible columnar structure defines the view of the Tower. On the Tower Trail, you can walk a loop around its base and see the formation from different angles.

Rock Formation, Nature, and Trails

The Tower Trail is a 1.3-mile paved footpath that loops around the base of Devils Tower. Along the route, interpretive signs provide information about the park’s natural and cultural history. For visitors who want to focus on more than the rock formation, the signs also offer insights into the park’s themes right along the route. Hundreds of black-tailed prairie dogs live in the floodplain near the Belle Fourche River in Devils Tower National Monument.

For a different perspective, the Joyner Ridge Trail offers elevated views of Devils Tower as well as opportunities to observe wildlife in forests and flower-filled meadows. While the Tower Trail circles the base of the rock, the Joyner Ridge Trail focuses on elevated views and wildlife observation. There are also opportunities for stargazing around Devils Tower, including at the Joyner Ridge Trailhead and the Circle of Sacred Smoke Sculpture and Picnic Area. Conditions and program times may vary; check for planned night-sky programs before your trip.

Culture and Climbing Regulations

The Circle of Sacred Smoke is located near the picnic area and honors the American people as a symbol of world peace. The installation is also intended to raise visitors’ awareness of the significance of Devils Tower to more than twenty affiliated Indigenous tribes. This gives the site’s cultural significance a distinct place in visit planning, alongside its striking geological features.

Technical climbing is permitted in Devils Tower National Monument. Anyone wishing to climb above the talus field or undertake climbing-style ascents must register at the climbing kiosk before the ascent and check out afterward. The National Park Service asks visitors to voluntarily refrain from climbing Devils Tower throughout June and not to climb within the Tower Trail loop. Keep these guidelines separate when planning: the request applies throughout June, while registration is required for the specified ascents above the talus field.

Programs and Visit Planning

Summer ranger programs typically include guided walks on the Tower Trail, short talks in front of the visitor center, and evening programs in the campground amphitheater. The offerings thus include walks, short talks, and an evening program at the locations mentioned. Check the schedule for the year of your visit if you want to plan for a specific program.

The Junior Ranger program provides booklets at the visitor center and awards a badge upon completion. Booklet availability may vary by season. If this program is important to your plans, check current availability.

Getting There and Practical Information

Devils Tower National Monument is accessible by one road, Wyoming Highway 24. The access road is located nine miles south of Hulett. Check road conditions before setting out. Visitors can use three designated parking areas: the visitor center parking lot, the picnic area parking lot, and the Joyner Ridge Trailhead. Parking may be limited during busy periods, so some flexibility in your visit plans can be helpful.

There is no food service in the monument. You can refill reusable water containers at designated restrooms. A seasonal water station is available at the start of the Tower Trail from spring through fall. Take the different water options and seasonal programs into account when planning your day.
