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.
Located just north of the Montana-Wyoming state line, Tongue River Reservoir State Park is located 6 miles north of Decker on Secondary 314, then 1 mile east on county road
We didn’t have a great experience here but it was partly due to the hot weather. However, vault toilets were disgusting and our site (CP39) was on a gross stagnant part of the lake and you couldn’t get too close to the water because it stunk so bad.
A wonderful place to go. Spent five days there and had a great time. They have places to camp with electric and without. We stayed at rattlesnake camp ground. No electric but had public restroom and fire ring. Only a few sites there so it was quit. Loved it and recommended it. The lady who owns the marine was very delightful. You got to try their Indian tacos on Saturdays and burgers any other day. A little pricey, but we'll worth it. UPDATE....Just got back from out third year family reunion at tongue river. Another great week. I want to add a "ata boy" to the folks at the Tongue River Parks office. We had a camper snap an axle while there. We went to Sheridan and spent half a day trying to find a new one, or someone to weld this one. In desperation we went to the Parks office and they gladly let us use their shop, wielder and tools to fix our axle and get it back on the road. Thank you guys for making a bad situation much better. Just for the record, my weld held and we got it the 200 miles back home.
Nice park/RV/Camping! Very beautiful scenery, good fishing (even from shore). The staff at marina store were very nice. The only down fall I could see was no showers for people like me who tent camp.
Only spent a night on a stop over. Beautiful spot. Most sites are easy water access. Looked like a great place to fish. Sites are quite spread out. Really good stocked store at the campground. Awesome place. Hope to make it back someday.
Camp here on November 17th. 2023. No one is here. Temperatures are still holding in the upper 50's. Sites 1 through 11 have 50 amp service there is no water dump station is still open all year. Veterans can camp for $13 a night. This has been very enjoyable. Definitely will come back again.
