Ackley Lake State Park


In the heart of Big Sky Country in Montana, you’ll find Ackley Lake State Park. At an elevation of 4,336 feet, the park has spectacular views of the Little Belt and Snow Mountains. The area is filled with rich agricultural land with the lake being the primary source of irrigation for local ranchers.

Named after an early settler, Ackley Lake also provided the famous western artist Charlie Russell with inspiration for his paintings. The land the state park resides on isn’t owned by the state of Montana. It is instead leased to the state from the Department of Natural Resource Conservation (DNRC). In 2016, Ackley Lake nearly lost its state park status, but after consideration and concern from nearby residents, it was renewed.

Ackley Lake is 160-acres with the park itself about 290-acres in size. There are a number of activities within the state park. Bring your boat and head out onto the water or instead take a swim near the shore. The lake provides an excellent source of fishing both in the warmer months and ice fishing during the winter months.

Lake Ackley State Park is open year-round. Campers can expect a primitive camping experience with no hookups and very few amenities. Campsites are available on a first-come, first served basis. The park doesn’t take reservations. Weekdays tend to be slower at the state park, though it does typically fill up on the weekends.
