Lava Lake Trailhead is a popular access point for both hikers and paddlers on the Gallatin River, located about 20 miles south of Gallatin Gateway.

The trailhead features multiple parking areas and serves as a take-out point for rafters and kayakers, though the access road has rough conditions with potholes and limited trailer backing space.

Congestion and streambank erosion are common issues during busy periods, and visitors should note that the site experiences heavy traffic on summer weekends.
