Lake Day Atlas

The Mission Mountains rise beyond long stretches of open water at Flathead Lake. At Big Arm on the west shore, you can spend the day at the water’s edge or arrange a crossing to Wild Horse Island.

On the water

Plan your lake day

Base a picnic at Big Arm, then take a planned boat trip to Wild Horse Island for a walk among ponderosa pines. Bring lunch, water and binoculars. The island is a day-use stop, so arrange a return ride before you go.

Field notes

Before you go

Parts of the lake lie within the Flathead Indian Reservation. Read the park’s permit guidance for your intended activity and stay on public land when exploring the islands.
