Tongue River State Park Campground
About
State Park
Enjoy this 12-mile-long reservoir situated among scenic red shale, juniper canyons, and the open prairies of southeastern Montana. The park is loved by Montana and Wyoming anglers, campers, and boaters. It provides excellent fishing as numerous "state record" fish have been pulled from its waters.
The park offers 81 reservable camping sites with electric hookups, with 27 of those being double occupancy campsites (two electric hook-ups), as well as over 80 non-reservable, non-electric camping sites. Most sites have a fire ring and a picnic table. A dump station and water faucets are available during peak season, as weather permits. The park also has a fish cleaning station and over 20 vault toilets throughout the campgrounds. There are 2 boat ramps with docks for launching boats, one at Camper Point by the marina and one at Pee Wee North.
Day use areas include sheltered picnic tables at Campers Point and Sand Point. Sand Point has a small, but popular “beach area” for swimming and picnicking.

Labor Day Fun
Our first time here. Pro -clean -wide spaces -quiet -electric only 50/30 -great store Con -very dusty -no trees/shade -very hot
Beautiful Sites
Gorgeous site, overlooking the lake. Water was great. Picnic table and electric at site.
What a Gem!
Beautiful captions with 5 different large loops. Wide area for each space. I found it quiet even on a full weekend. Really well laid out. This is an irrigation Reservoir, so it is drawn down as the summer goes on. Big Wall Eye fishery.

Wow!
Really amazing place. Thr vast majority of the sites are on the waterfront. Nice reservoir. I heard the fishing is great. Probably really busy in the summer. I visited in late October, so I pinky had one neighbor. Spaces are fairly private. Not many trees, fyi. Majority of sites have electric. Some double spaces on the water. Nice for groups. Picnic tables at each site. No wifi. ATT worked, my neighbor's Verizon did not. $30/ night with electric hookup.
Great Place to Recreate
Cool place. VERY bumpy and dusty gravel road to camp sites. Vault toilets and trash cans around but no hook ups for RV. Fun little playground at the Peewee Point camp area. No privacy between sites but enough space for comfort.

Tongue River is a gateway into Montana
Tongue River Reservoir State Park was our last stop before arriving at our destination in Helena, MT. Quiet park not far from the interstate surrounded by a wonderful lake. Facilities were very clean and the area is quite flat. No problem leveling RV. Did not use any of the facilities so I cannot comment. However, watching the boats come in at sunset was very relaxing. The Montana landscape and how it changes colors as the sun sets was beautiful.

Nice Campground
Campers Point (South) was a nice paved campground with electric hookups. We ended up at the very end of the loop. It was a big campsite with a dirt burm behind us. I think that helped with blocking the evening winds but it took a little away from the lake views (behind the trailer at least). We did have immediate access to the water as well. There was lots of room to easily navigate through to our site. The site was clean and held my 28ft trailer, my longbox truck, SxS and even our friends ski boat . Good space in between campsites. The reservoir was nice, not too big but not too small. Lots of trees in the water so boaters just need to we watchful. Some people we knew were camped in one of the dirt camp sites (Pee Wee South) and camps were packed in there like sardines! We were more than pleased with our campsite and the layout. If you're going to reserve a spot I recommend Campers Point (South) and pay a little extra for the pavement spots and electric hookups. It was well worth it.
Great waterfront sites available!
Best to reserve your spot early if you want a waterfront site with power. If you are tent camping there are plenty of walk up sites. Fire pits and picnic tables at the sites and group sites are available. Outhouses are kept very clean and there is access to water throughout the State Park.
