The East River Road is a pleasant road ride for cyclists who don’t mind a few potholes. Mountain bikers will want to turn off the main road and head up into the hills.

The upper stretches of the Yellowstone River, particularly through Yankee Jim Canyon, have some challenging white water. After the river leaves the canyon and enters the Paradise Valley, it calms down enough for novice floaters to navigate it without much difficulty.
