Great location
I stumbled across this campground while driving Mesa Falls scenic by-way. This campground has 27 sites, both tent, RV and a group site right along the Warm River. It also has a day use area. This campground had new vaulted toilets but no showers. Within the campground was the trailhead for The railroad grade trail (great for mountain biking) which I was told use to take train passenger to Yellowstone’s old faithful. Tubing was very popular and the campers next to us insisted that we borrow their tubes so we could try it out for ourselves, very refreshing during our hot August stay.
I snagged the last tent site #21 across the bridge in the northern half of the campground. This large secluded tent site up on the hill had a very small tent pad, fire pit and picnic table and enough room to put up my hammock. This site is next to two double sites. Unfortunately during the 5 nights I stayed some of the RVers close to us ran their generators beyond the 10pm curfew and one RVer felt the need to pull out his noisy leaf blower and blow leafs and dirt everywhere.
There is tons of things to see and do in the area, Mesa Falls, Island Park… but the hidden gem is the close proximity (less than 25 miles) to Yellowstone National Park - Bechler Ranger Station. Bechler Ranger Station is in the far SW corner of Yellowstone National Park. This area has more streams, creeks, lakes and waterfalls than any other area in Yellowstone. There is a historic Soldier Station there that is about 100 years old and there are lots of hiking trails to beautiful waterfalls. You can see cave falls right from the parking lots. I would definitely return to this campground next time I am in the area.
