About this campground

Six distinct campgrounds—from the aptly named Rattlesnake to the waterfront havens of Sand Point and Campers Point—offer 156 total campsites, including 81 reservable spots for those who plan ahead. Whether you're casting a line at dawn, launching your boat into crystal-clear waters, or settling in for a night under Montana's vast sky, this park delivers the authentic Western outdoor experience that draws visitors back season after season.
Tongue River State Park accommodates a variety of camping styles. It offers primitive camping, RV sites, and group camping options, with some areas providing electricity hookups and others being more basic.

While winter brings freezing temperatures and light dustings of snow, the magic truly unfolds as spring arrives. Plan your perfect getaway during Week 18 in early May, when temperatures climb to a comfortable 64°F during the day and cool to 40°F at night under predominantly clear skies. Summer reaches its peak during Weeks 26 and 28, with glorious 83-88°F days perfect for water activities, while evenings cool to a pleasant 62°F—ideal for campfire gatherings. With 90% clear skies during peak season, you'll understand why seasoned campers mark their calendars for these golden weeks.

Natural Features and SceneryPrepare to be captivated by Tongue River's striking landscape, where ancient red shale cliffs rise dramatically from the water's edge, creating a photographer's paradise at every turn. Wind-carved juniper canyons provide intimate exploration opportunities, while expansive prairies stretch toward the horizon, offering that quintessential Big Sky Country experience. The centerpiece reservoir reflects the changing moods of Montana's sky, from brilliant sunrise oranges to deep sunset purples. As seasoned visitors note, this is high desert country—the sparse tree coverage means unobstructed views and star-filled nights, though shade seekers should come prepared with canopies for those warm summer days.
Geological RegionTongue River State Park showcases southeastern Montana's remarkable geological tapestry, where millions of years of natural forces have sculpted a landscape unlike anywhere else. The park's signature red shale formations tell an ancient story written in stone, while juniper-dotted canyons carve intimate corridors through the terrain. This unique ecosystem bridges the gap between Montana's mountainous regions and its eastern prairies, all centered around the serpentine 12-mile reservoir that has become both a recreational paradise and a vital water source for the surrounding high desert environment.
