Mammoth Springs Campground

SUMMARY PRESENTED BYT-Mobile

Mammoth Springs Campground sits in St. Joe National Forest outside camping near Avery, accessible via a rough road that warrants a careful approach. The campground runs July through October, has drinking water and toilets, and can accommodate RVs up to 40 feet. It draws ATV and motorized recreation users, so expect engine noise. Hikers and those sensitive to motor traffic may find the surrounding forest a quieter alternative. Pack in extra ground clearance if road conditions have been wet.

Great for motorized veichles

I don’t do a lot of Atv ect. so I did not like all the loud motors that much but a lot of people apparently like this area for that. I hiked a ways and did some practice shooting, and it seemed like it would not bother people to have noise in the distant background.

I ended up not staying the night at this campground and opted to explore the forest nearby which was away from people enjoying the riding areas.
