Beaver Creek Park is part of a unique area in North Central Montana Plains Country, the Bears Paw Mountains. The Park is a 10,000-acre strip along the North slopes of the Bears Paw Mountains, about one-mile wide by 17 miles long, and is one of the largest county parks in the Nation. Beaver Creek Park is a natural recreation area that offers unlimited opportunities for recreation during all 4 seasons. Within the park are two lakes that are open to fishing all year round and are well stocked with Rainbow and Brook Trout. Stream fishing opens the 3rd Saturday in May. There are many developed camp and picnic grounds in the Park. Most are equipped with tables, fire grates and vault toilets. Smaller campgrounds don't require prior reservations but some special areas may be reserved for large group activities.
