Summary

The campground is situated near the Gros Ventre River and is just a few miles away from the Bridger-Teton National Forest, making it an ideal spot for outdoor enthusiasts.

The area is known for its abundant wildlife, including elk, deer, moose, and bears. Visitors can explore nearby hiking trails, go fishing in the river, or enjoy a scenic drive through the nearby mountains.

The campground offers a range of amenities, including picnic tables, fire pits, and vault toilets. There are 17 campsites available on a first-come, first-served basis, so it’s best to arrive early to secure a spot.

An interesting fact about the area is that it was once the site of a major earthquake in 1959, which caused a massive landslide that created a natural dam in the Gros Ventre River. The resulting lake, known as Lower Slide Lake, is a popular spot for fishing and boating.

The best time to visit Three Mile Campground is during the summer months when temperatures are mild, with average highs in the mid-70s to low 80s Fahrenheit. Visitors should note that the campground is only open from June to September.
