Toston sits on the banks of the Missouri River in between Helena and Three Forks on US Highway 287. Toston provides ready access to the Missouri. The stretch of river between Three Forks and Townsend has become popular as anglers have discovered the area's exceptionally large trout. The Lewis and Clark Expedition made nine camps on the short stretch of river between the Toston Dam and the south end of Canyon Ferry Reservoir. The Toston Dam Recreation Site, five miles south of Toston, has seven campsites and is an excellent spot to picnic, camp or boat while traveling the Missouri.
