Just past Kelly Warm Spring, which is a cool 80-degree Fahrenheit spring surrounded by a grassy meadow (it's not recommended to enter the water due to high levels of E. coli and the presence of Naegleria fowleri.), there are some cool jumping rocks to get your adrenaline rushing.

On Gros Ventre Road, take the first pullout on the right past the Springs. Park and walk west 150m to the cliffs. Usually there are a few people jumping and chilling on the rocks!

BTW- the area has historical significance, as it was once a town founded by William Kelly in 1907, which was later flooded in 1927 after a massive landslide dammed the Gros Ventre River.
