The Best Boat Rentals in Flathead Lake

Most self-drive pontoons and bowriders on Flathead Lake run roughly $400–$900 for a full day, with smaller powerboats sometimes available around $100–$150 per hour. Premium wake and surf boats typically range from about $800–$1,500 per day, or $150–$250 per hour when booked with a captain. Captained sightseeing cruises usually price by the hour for your private group. Your rental generally includes USCG-approved life jackets, the required safety kit, lines, an anchor, and often a bimini or shade plus Bluetooth audio. Fuel, taxes, and damage deposits are usually extra; some owners charge delivery or cleaning fees. Always review the listing’s “What’s included” and “Extras” so there are no surprises at checkout.

You’ll find an easy mix for any crew: comfortable pontoons for relaxing and swimming, bowriders and deck boats for cruising, dedicated wake and surf boats with ballast for watersports, and a handful of jet boats and sailboats. Larger cabin cruisers exist in smaller numbers. If you’re planning watersports, look for listings that include boards, tubes, or tow ropes or add them as an optional extra.

Choose a captained trip if you want a stress-free day, local route knowledge, or watersports coaching. Go self-operated if you’re comfortable at the helm and want maximum flexibility. Many owners will offer both options depending on the boat and your experience; high-performance wake boats are often captained or require strong prior experience. For groups celebrating or families who just want to relax, a captain often ends up being the easiest path.

Common pickup and launch points include Wayfarers State Park in Bigfork on the northeast shore and the Somers Fishing Access Site at the north end. On the south end near Polson, renters frequently meet at Salish Point or Riverside Park. Popular west-shore options include Big Arm State Park (also a jump-off to Wild Horse Island) and the marina and ramp at Finley Point State Park on the southeast shore. West Shore State Park, just south of Lakeside, also offers a deep-water launch. Confirm the exact meetup when you book—many owners can deliver to your preferred side of the lake for a fee.

Expect big mountain views of the Mission Mountains to the southeast and the Swan Range to the east, rocky coves and clear water along the West Shore, and cherry orchard country on the east shore near Yellow Bay. Cruising Big Arm Bay gives you views toward Wild Horse Island, where you may spot bighorn sheep, mule deer, bald eagles, and, with luck, the island’s namesake wild horses from the boat. Sunset cruises often glow over the lake’s western ridges—bring a camera.

Montana does not require a boating license for adults. Operators ages 13–14 must have an approved boater education card (or be accompanied by an adult), and most owners require renters to be at least 18 years old with valid ID. Even if you’re experienced, owners may provide a brief safety and lake orientation at pickup, which is a great time to ask about local no‑wake zones and recommended routes.

Yes—families are welcome. Every rental includes properly sized USCG-approved life jackets. In Montana, children under 12 must wear a life jacket on moving motorboats under 26 feet, and it’s smart practice for all kids anytime the boat is underway. Tell the owner your child count and approximate sizes when you book so life jackets are ready at check-in. Boats also carry required safety gear like throwable flotation and signaling devices.

Absolutely. Most owners allow coolers, snacks, and beverages. Glass is discouraged on the water, and some captains may restrict red wine or staining drinks. If you plan to grill, ask in advance—most boats don’t allow open flames. Passengers can enjoy alcohol, but you must designate a sober operator on self-drive rentals; captains will monitor safety and may limit service if conditions get choppy.

Many owners allow well-behaved dogs, often with a small cleaning or pet fee and a preference for soft paws to avoid seat damage. Some high-end wake boats or freshly reupholstered vessels may be pet-free. If your dog is joining, bring a non-slip mat, a collapsible water bowl, and consider a canine life jacket. Always confirm the pet policy in the listing before you book.

Summer brings plenty of calm mornings, with breezier afternoons common, so earlier departures are often smoother for cruising and watersports. Owners publish clear cancellation policies on each listing; if the captain or owner determines conditions are unsafe (for example, thunderstorms or high winds), you’ll generally be offered a reschedule or refund per the policy. Pack layers—the water stays cool into June—and keep an eye on your in-app messages the evening before for any weather updates.

Yes—pontoons and deck boats are perfect for groups, and captained cruises make hosting effortless. Share your headcount, preferred pickup, and timing in your inquiry so the owner can recommend the right boat and route. Many hosts can suggest swim coves, photo stops, or a plan that includes dropping you near lakeside restaurants. For weekends and holiday dates, book early and consider a morning or sunset time slot for lighter traffic and prettier light.

Peak boating runs mid‑June through early September, with the warmest water typically in late July and August. Memorial Day weekend kicks off the season, July 4th week is the busiest (Bigfork’s beloved Fourth of July parade adds to crowds in town), and Labor Day caps summer. Notable lake events can influence ramp traffic: spring (March–May) and fall (September–November) Mack Days fishing tournaments increase activity at check‑in sites like Somers, Big Arm, Wayfarers, and Salish Point, and the Montana Cup sailing regatta at Somers typically occurs in early August. For the calmest water and easier parking, choose weekdays and morning departures; late afternoons can be windy but make for gorgeous golden‑hour cruises.

Plan routes that match your pickup point—for example, from Bigfork you can explore Wayfarers’ rocky shorelines and the north‑east coves; from Polson, tour Polson Bay, Finley Point, and the east shore. Respect posted no‑wake zones near marinas and shorelines, and give wildlife plenty of space, especially around Wild Horse Island. If you’re trailering from out of the area, budget time for aquatic invasive species inspections; when you rent on the lake, the owner handles boat compliance.

Yes—Wild Horse Island is a favorite day stop, accessible only by boat. There’s no public dock, so use one of the designated shoreline landing areas and keep clear of private property. The island is day‑use only with no camping, and pets aren’t permitted to protect wildlife. Bring sturdy shoes, water, and sun protection if you plan to hike. From Big Arm or Dayton the approach is short; from the north end it’s a longer but scenic cruise, so watch the forecast and aim for a calm‑morning crossing.
