Think pine-covered hills, rocky cliffs, and crystal-clear water that shifts from deep blue to vibrant turquoise. Wildlife is everywhere, too. You might spot eagles fishing, otters playing along the shore, or even the famous wild horses of Wild Horse Island.

Best Water-Based Tours on Flathead Lake

Boat Tours & Cruises

One of the best ways to take in Flathead Lake's sheer size and beauty is from the water. Scenic boat tours let you sit back and soak in panoramic views of the towering Mission and Swan mountain ranges while learning about the lake's history, geology, and unique ecology.

For something extra special, hop on a sunset cruise. 

As the sky turns shades of pink and orange, you can sip a drink, snap incredible photos, and enjoy a peaceful ride across the water. These cruises are great for couples or anyone wanting a relaxing evening experience.

Families will love guided wildlife-spotting tours. You might see bald eagles, ospreys, otters, and occasional bears along the shoreline. Many tours depart from Bigfork, Polson, and Lakeside, making finding a launch point near you easy.

Kayak & Paddleboard Adventures

If you prefer a hands-on way to explore, kayaking and paddleboarding let you experience Flathead Lake up close. Wild Horse Island is one of the top paddling destinations, offering secluded beaches, hiking trails, and the chance to spot wild horses, bighorn sheep, and mule deer. Many outfitters provide boat shuttles and guided kayak tours to make the trip hassle-free.

Paddleboard and kayak shops are available for rental in Lakeside, Bigfork, and Polson. Hourly or full-day rentals are available. Guided paddleboarding experiences are also available if you want extra tips and a scenic tour with a knowledgeable local guide.

If you're looking for hidden gems, paddle to the lake's many coves and inlets. Places like Yellow Bay and Skidoo Bay have calm, clear waters that are perfect for exploring.

Fishing Charters & Lake Angling Trips

Flathead Lake is a dream destination for anglers, with deep waters teeming with lake trout, whitefish, and even the occasional pike. Whether you're a seasoned fisherman or trying it for the first time, booking a guided fishing charter can make a huge difference. Local experts know the best fishing spots and provide all the gear, making it an easy and stress-free experience.

Top-rated fishing tour operators like Mo Fisch Charters and Flathead Lake Charters depart from key locations around the lake. Depending on the season, you might catch trophy-sized lake trout, which can grow over 20 pounds!

If you're a beginner, don't worry—guides will help with everything from casting to choosing the right bait. Dress in layers, bring a hat and sunscreen and get ready for a day on the water with plenty of great fishing stories to take home.

Somers Bay LED Kayaking

Try an LED kayak tour at Somers Bay for a one-of-a-kind nighttime adventure. These specially designed clear-bottom kayaks are lit with vibrant LED lights, glowing as you paddle over the dark, still waters. The illumination lets you see fish swimming below, creating a mesmerizing, otherworldly experience.

Unlike daytime paddling, this tour is all about the quiet beauty of the lake at night. There's something magical about gliding across the water with only the stars above and the gentle lapping of waves around you. The tour guides keep the group small for an intimate and peaceful experience.

Booking in advance is a must, as this unique tour fills up quickly in the summer. Wear warm layers, as it gets chilly after sunset, and bring a waterproof bag for your phone if you want to capture the experience.

eFoil Flathead Lake Experience

If you're looking for a high-tech, adrenaline-pumping way to explore the lake, foiling is it. An eFoil is an electric-powered hydrofoil surfboard that lets you hover above the water as you ride. It's a mix between surfing and flying—without needing waves!

Flathead Lake has several outfitters offering eFoil rentals and lessons with instructors who can help you learn quickly. Some best places to try foiling include the calm waters near Woods Bay, Somers Bay, and the west shore near Lakeside.

Beginners should opt for a guided lesson, where you'll learn balance techniques, speed control, and safety tips. Most rental packages include helmets and life jackets for extra safety. If you love water sports, this must-try experience will leave you feeling like you are floating on air.

Unique & Specialty Tours Near Flathead Lake

Wild Horse Island Boat & Kayak Tours

Wild Horse Island is one of Montana's most unique places. It is a massive, undeveloped island in Flathead Lake, home to wild horses, bighorn sheep, and miles of hiking trails. Since there's no public ferry, the only way to get there is by private boat, guided tour, or kayak.
