Boiling River

A delectable mix of hot and cold

Save to my Account

Bathers flock to the point where the large hot spring known as Boiling River pours over travertine rock and into the chilly Gardner River. The 140-degree water is thought to flow underground from Mammoth Hot Springs, a couple of miles to the south. The water temperature varies substantially along the 150-foot-long band of pools; position yourself just so and you can freeze your fanny while toasting your toes.

The turnoff to Boiling River is 3/4 of a mile south of the 45th Parallel pullout. Bathing suits are required and no alcoholic beverages are permitted; the pools are closed during the high water of spring (they generally reopen by late June). Watch for bison, elk, and bighorn sheep in the immediate area.
