Boating is allowed on most of Yellowstone Lake and on Lewis Lake. Only non-motorized boating is allowed on most other lakes. Only one river is open to non-motorized boating: the Lewis River channel between Lewis and Shoshone lakes.
Permits are required for all boats and float tubes. Boaters must have a Coast Guard approved wearable flotation device for each person. All boat permits (motorized & non-motorized) can be purchased at the South Entrance, Grant Village Backcountry Office, and Bridge Bay Ranger Station. Float tube only permits are available at the Mammoth, Canyon and Old Faithful backcountry offices, Northeast Entrance, and Bechler Ranger Station.
All boats will be inspected by NPS rangers for Aquatic Invasive Species (AIS) when obtaining a permit. As a precaution, any type watercraft suspected of harboring AIS will be subject to a non-chemical decontamination treatment.
The use of jet skis, personal watercraft, airboats, submersibles, and similar vessels is prohibited in Yellowstone National Park.
