The largest, natural, freshwater lake this side of the Mississippi

Flathead Lake contains 200-square miles of water and is ringed by 185 miles of shoreline. The Flathead and Swan rivers, both of which run through Bigfork, feed fresh water into Flathead Lake year-round.

Locals and visitors alike treasure Flathead Lake for its spectacular beauty and endless opportunities for water recreation, including fishing, motor, sail or paddle boating, hiking, camping and swimming.

Visitors can also enjoy a picnic and camp or hike through the vast public lands that surround the lake, including six state parks and nine fishing access points.

Another must-see landmark is Wild Horse Island, a 2,165-acre state park located on the largest island in Flathead Lake. It is only accessible by boat, but the daytrip is worth it to see wild horses and the world-record setting Rocky Mountain bighorn sheep that live there.

Many visitors remark that the residents of Bigfork don’t know how lucky they are, but that couldn’t be farther from the truth! It is impossible to become desensitized to such a stunning vision. The lake is a source of daily inspiration and year-round recreation for all of us.
