Flathead Lake, Montana’s largest natural freshwater lake, stretches over 190 square miles of pristine water framed by rugged forests and soaring peaks. It’s a destination cherished for its crystal-clear surface, abundant wildlife, and array of water-based recreation. Riverside Recreation, located in Polson, MT, captures the lake’s spirit through their standout offering: the Upper Deck 25' Slide Pontoon. This spacious tri-toon boat elevates lake days into memorable aquatic adventures.
The Upper Deck pontoon is a double-deck vessel designed for both relaxation and excitement. With a capacity of up to 13 passengers, it features a sun deck perfect for soaking in the expansive lake views and a built-in water slide that delivers spontaneous bursts of fun. Its stable tri-toon hull offers smoother rides even in choppier water, allowing guests to comfortably cruise, swim, and socialize. The premium onboard stereo supports Bluetooth and USB connections, filling the air with your soundtrack as Flathead’s mountains and pine-draped shoreline roll by.
One of the area’s defining traits is its combination of crystal-clear waters against a backdrop of ancient glacial geology and dense evergreen forests. Wildlife such as osprey and bald eagles circle overhead, while underwater, the lake supports native fish species prized by anglers. Polson serves as the gateway city, blending small-town charm with outdoor access.
Riverside Recreation’s Upper Deck Slide Pontoon offers 4-, 8-, and 12-hour rental options, accommodating flexible itineraries for families, friend groups, or solo wanderers seeking downtime or lively splash sessions. Unlike many rentals, this pontoon provides a balance of slick and stable that suits varying skill levels and interests.
Whether you’re here to glide across quiet coves, dive from the slide into cool waters, or simply anchor and take in Montana’s vast blue canvas, Riverside Recreation is a premier outfitter turning Flathead Lake boating into a signature adventure experience rarely matched in the region.
