West Shore State Park boat ramp is a deep-water launch on Flathead Lake's west shore near Lakeside, Montana, typically ice-free throughout winter and recently extended by 15 feet to accommodate increased use.

The ramp serves as a popular early-season launching point and supports both motorboats and paddlecraft, with amenities including a dock, vault toilets, drinking water, and nearby camping facilities.

The park is situated on glacially-carved rock outcrops offering scenic views of the Mission and Swan Mountains, with 2. 5 miles of hiking trails and a rocky shoreline suitable for swimming and fishing.
