The Smith River Access Trail in Lewis and Clark National Forest provides on-foot access to a section of the Smith River canyon near White Sulphur Springs, Montana. The river is nationally known as a float fishing destination with a heavily competed permit system, but this hiking trail offers a different kind of access: quiet, unhurried, and permit-free.

The Smith River cuts through limestone canyon walls in this section, and the riparian corridor along its banks is rich with bird life and wildlife that make the gentle trail particularly rewarding for patient observers.

The Route

The trail follows the river downstream from the trailhead through a mix of cottonwood and willow riparian forest and open bench terrain. The canyon walls rise to the sides in places, creating a narrow landscape that is distinctive in the largely open terrain of central Montana. The turnaround at 1.75 miles sits at a viewpoint above a bend in the river.

The trail stays relatively flat throughout, following the natural contours of the riverbank. It is easy to extend the hike by continuing downriver beyond the marked turnaround if conditions allow.

What to Expect

Spring and fall are the most active wildlife seasons here. Waterfowl migration in April and October can be excellent along the river. Beaver are active in the morning and evening, and their dam work is visible at several points along the route.

The trail can be wet in early spring when the river is running high from snowmelt. Check conditions before visiting in April or early May.

Nearby

White Sulphur Springs is the closest town with services, just a few miles from the trailhead. The Spa Hot Springs Motel in White Sulphur Springs offers natural hot springs soaking, a welcome option after a long day in the field. The Lewis and Clark National Forest's Little Belt Mountains are accessible from the same area for hikers wanting more elevation.

Leave No Trace

This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
