Caprock Coulee Nature Trail

Overview

This North Unit classic starts as a self-guided, family-friendly stroll through the badlands and can scale into one of the park’s best hikes. The nature trail itself is about 1.5–1.6 miles total (out-and-back) from the same trailhead, with 21 numbered stops that unpack the area’s geology, flora, and fauna. If you keep going, it becomes a 4.1–4.4 mile loop with roughly 600 feet of climbing—moderate overall, with a few steeper, stair-filled stretches and airy ridge walking. Expect layered bluffs, cedar-choked coulees, grassy buttes, and sweeping Little Missouri River views.

Route and highlights

From the trailhead, the nature walk drops into a narrow coulee lined with colorful, layered rock. Keep an eye out early for a large chunk of petrified wood near the path. The interpretive posts make this a great primer on caprock—hard sandstone "caps" that shield softer clay columns—and on the plants that survive in this rugged landscape.

Continuing past the nature trail turnaround transforms the outing into the full loop: you’ll climb to broad, grassy ridges, cross the paved Scenic Drive, optionally swing by the stone shelter at River Bend Overlook for a signature Little Missouri viewpoint, then finish on a narrow, broken ridge studded with caprock formations. For the most dramatic finale, hike the loop counter-clockwise so the ridge and big views come at the end.

Difficulty and who it’s for

The nature trail portion is easy and great with kids—flat to gently rolling—but it can be muddy after rain. The full loop is a step up: still approachable for most hikers, but expect sustained climbs, stairs, and some steep, slick sections if wet. Poles help on the clay. If the main lot is full or the road is affected by closures, you can start at River Bend Overlook and do an out-and-back along the ridge for maximum scenery with minimal commitment.

Wildlife and what to look for

Bison commonly roam these hills; give them plenty of space. Deer and bighorn sheep are possible, and a nearby prairie dog town is a kid favorite. In warm months, prairie rattlesnakes are active. On the geology front, the caprock hoodoos and multi-colored badlands layers are the stars—those bands of sandstone and clay tell the story of ancient rivers, swamps, and ash falls.

Safety and conditions

There’s little shade and no water on the trail—carry what you need. After storms, expect slippery clay, washed‑out erosion steps, and the occasional downed juniper or light brush to navigate. Cacti and poison ivy lurk off-trail; mind your step and clothing. Trail signage near the initial split can be confusing—grab the interpretive pamphlet if available so you don’t miss the nature walk section. Seasonal road or lot closures do happen; be ready with the River Bend Overlook start as a backup.

Best time to hike

Spring and fall bring the friendliest temps and crisp views. In summer, start early or go late for cooler air and softer light on the striped bluffs; midday heat and exposure are real here. Skip the ridge descent if rain is in the forecast—the clay turns treacherous. Winter can be beautiful but icy or snowbound; allow more time and traction if you go.
