The Soda Butte/Lamar River Trailhead features a large parking lot and serves as the primary access point for multiple trails in the Lamar Valley area, including the Lamar River Trail which follows Soda Butte Creek at its start via a wooden bridge crossing.

The trailhead is located 15 miles east of Tower Junction on the Northeast Entrance Road, with no restrooms or water available on-site (nearest potable water at Tower Junction).

This location provides excellent access for both day hikes and backcountry trips, with opportunities for fishing and wildlife viewing throughout the valley.
