Flagg Canyon Launch

Location: Access from US 89/191/287 just south of the Yellowstone South Gate. A steep dirt road leads from the picnic area down to the boat ramp. The ramp is a log slide that provides access to the river bottom. Except during high water, visitors will need to carry their boat to the water. Notes: There is a small picnic area above the launch with a vault toilet. The Flagg Canyon trail continues south from the boat launch along the rim of the canyon.
