Closed

The river is usually closed to swimming until mid-summer due to high water and strong currents. During years with significant snowpack and runoff, the swim area may remain closed for the entire season. Check our current conditions page for status. Water wings are allowed and life jackets are recommended.

Limited parking is often full and overflowing.

More Soaking & Swimming

Swimming is not recommended in Yellowstone, and is occasionally prohibited, because most lakes and streams are dangerously cold.

Think Safety, Act Safely

From burning hot hydrothermal features, to unpredictable wildlife, to steep terrain, Yellowstone is a dangerous place. You are responsible for your safety. As such, please remember these safety tips:

  • Never touch any hydrothermal waters—they can scald you.
  • Observe safe distances from all wildlife.
  • Stay behind fencing, guard rails, and ledges.
