Mack’s Inn River Adventures

Drift down the North Fork of the Snake River (Henry’s Fork) with Mack’s Inn River Adventures, where tranquil waters meet breathtaking mountain scenery. Our leisurely 5‑mile float offers a unique opportunity to see moose, elk, deer, trout, kokanee salmon, eagles, swans, and more — all while you relax with family and friends. 

Whether you choose a raft, kayak, canoe, stand-up paddleboard, or tube, each launch includes paddles, life jackets, and a shuttle from our resort to the river’s launch point. 

No matter your skill level, Mack’s Inn makes it easy — just bring your cooler, snacks, sunscreen, and a dry bag for valuables. Rentals are available Memorial Day through Labor Day. 

Start your adventure with us. Breathe in the fresh mountain air, drift under open skies, and experience Island Park’s natural beauty from the river.
