Tribal history
Incorporated in 1910, Polson sits in a natural amphitheater at the lake’s south end per Montana’s Flathead Lake. The town is the prime cherry-growing hub — roadside stands sell Flathead cherries from mid-July through mid-August. The annual Flathead Cherry Festival fills downtown July 25–26, 2026.
The south half of Flathead Lake falls within the Flathead Indian Reservation. Non-tribal visitors hiking, biking, or camping on tribal lands need a CSKT tribal recreation permit, sold at local retailers. The Polson marina offers boat launches and rentals for exploring the lake’s open water.
Bigfork
Live theater
Fine dining
Kayaking
Bigfork sits where the Flathead River empties into the lake, creating a natural harbor. The village hosts live theater from May through Labor Day at the Bigfork Summer Playhouse, plus a 27-hole golf course and kayak rentals from Base Camp Bigfork per Montana’s Flathead Lake.
The 10.8-mile Crater Lake Trail (recommended July–October) starts nearby and leads to a waterfall and subalpine lake. Base Camp Bigfork delivers kayaks and paddleboards directly to the water — no vehicle shuttle needed.

Panoramic views
Lakeside hosts several guided boat tour operators including Go Sail Flathead Lake (sailing lessons and charters) and Boat Rentals and Rides at Big Arm, just 15 miles south. Blacktail Mountain Ski Area above Lakeside offers groomed runs in winter with panoramic views of both the lake and Glacier National Park.
The 9-mile Blacktail Mountain Trail loop is accessible by mountain bike or on foot from late spring through fall. Evening summer boat tours from Somers let you watch the sun set over the Mission Mountains reflected in the lake.

The guided Wild Horse Island Kayak Tour departs from Lakeside and paddles the island’s eastern shore. Watch for bighorn sheep on rocky bluffs and bald eagles circling overhead. Bring water and sun protection — the island has no facilities or services.

Deep-water launch
West Shore State Park sits 6 miles south of Lakeside on US-93 and offers 33 campsites (7 tent-only, 1 ADA accessible) with direct lake access for hiking, picnicking, swimming, kayaking, and paddleboarding per Montana FWP. Kayak and paddleboard rentals are available on-site — no need to haul your own gear.

Wayfarers covers 67 acres near Bigfork on the northeast shore and maintains 30 campsites including a 9-pad hike-bike site for cyclists arriving without a vehicle. Showers are available — a welcome luxury where other park units lack them per Montana FWP.
The boat launch provides direct lake access for kayaking and fishing. Location near the Flathead River outflow also opens river paddling as an option. Bigfork’s village is minutes away on foot.
Finley Point State Park
Boat slips
Boat camping
East shore
Located 12 miles north of Polson on the southeast shore, Finley Point offers 18 RV sites with electricity (1 ADA accessible), 7 tent-only sites, 4 boat camping slips with electricity, and 14 standard boat slips per Montana FWP. This east-shore position puts it close to mid-lake fishing grounds.
The electric hookups for boat camping are rare on Montana lakes, making Finley Point popular for families with larger vessels. RVs up to 40 feet are accommodated throughout the park.
Yellow Bay State Park
Sunbathing
Kayaking
Deep-water launch
Situated 14 miles south of Bigfork on MT-35, Yellow Bay offers 5 tent campsites on a first-come basis, making it best as a day-use destination or spontaneous overnight stop. The park’s deep-water boat launch stays ice-free year-round per Montana FWP. The east shore surrounding the park is lined with cherry orchards.
Activities include swimming, sunbathing, and kayaking from the small beach. The University of Montana maintains a biological field station nearby. The clear water here is particularly good for snorkeling during the warmest weeks of July and August.
Boating, Fishing & Water Sports
Flathead Lake supports year-round fishing for Mackinaw (lake trout), kokanee salmon, yellow perch, northern pike, bass, and whitefish. The lake is 30 miles long and 16 miles wide with a maximum depth of 370 feet — large enough for serious fishing and sailing per Flathead Lake Biological Station, University of Montana.
Several outfitters offer guided experiences. Flathead Lake Charters (established 1979) runs fishing trips and scenic cruises. Big Sky Fishing Charters departs from Bigfork, Lakeside, and Somers for 4-hour tours. For sailing, Go Sail Flathead Lake operates from Big Arm with lessons and charters.
