Cooney State Park sits along a reservoir in south-central Montana's high plains, roughly 4,200 feet above sea level. The park offers five campgrounds with tent, RV, and group sites. Nightly fees run $25-$35, and the park accepts both tents and RVs. Group sites accommodate up to 16 people and two camping units.
Cooney State Park offers diverse camping options, including primitive camping, RV camping, and tent spaces. Group sites are also available.
Weather and SeasonsSummer brings the best conditions for visiting. Daytime temperatures typically reach the mid-70s to low-80s F, with nights cooling to the 40s and 50s. All five campgrounds and boat ramps operate fully during these months, and the reservoir stays active for boating, swimming, and fishing. Expect crowds on weekends and holidays. Reserve lakeside sites ahead and arrive early for boat-launch access. Winter drops temperatures significantly and brings snowfall, opening opportunities for cross-country skiing and ice fishing.
