Boulder River Outpost

Nestled in one of Montana's most breathtaking valleys between the majestic Beartooth and Absaroka mountain ranges, Boulder River Outpost is an intimate, unpretentious fly-fishing lodge offering unparalleled access to a wide range of pristine waters. Located along the East Boulder River, just a half-mile from the main Boulder River and twenty miles from Yellowstone National Park, the lodge is ideal for small groups of four to eight anglers.

Here anglers can explore a diverse range of fishing opportunities in all directions, including access to meandering small streams on private ranches, swift scenic freestone rivers, and technical spring creeks, all within easy reach of the lodge. Dry fly enthusiasts will find the Boulder Valley and its surroundings to offer some of the finest fly-fishing experiences in the state.

The Boulder River Outpost fishing program offers unparalleled variety and opportunities for anglers of all skill levels. With exclusive access to lightly-fished waters, including those within the National Forest and private ranches, guests can experience floating the Boulder River, as well as exploring the East and West Boulder. The legendary Yellowstone River, known for its trophy brown and rainbow trout, is nearby and offers great drift boat fishing throughout the season. Guests also fish the Stillwater River, Musselshell River, Sweet Grass Creek, Burns Lake, and Livingston Spring Creeks. Guests will fish two per guide and experience both boat based and walk and wade fishing.

The Boulder River Outpost is a simple, cozy operation that accommodates up to eight anglers. They have two cabins, a game room, and the main lodge provides a casual setting to unwind and share stories of the day's adventures. The smaller bunkhouse cabin has three bedrooms (bedroom 1 - single queen; bedroom 2 - double XL twins; bedroom 3 - single XL twin), a living area, full kitchen and single bath. The larger main cabin has two bedrooms (bedroom 1 - queen + XL twin; bedroom 2 - double XL twin or convert to king) and two bathrooms as well as a larger kitchen, mudroom and wader room. Each cabin has a wood stove and wood accents.
