The Middle Fork of the Salmon

The best rafting trip in North America is the Middle Fork of the Salmon. This multi-day adventure has something for everyone, whether you are an avid angler, history buff, thrill seeker, kid on summer break or just looking to enjoy nature, this is the trip for you.

The Middle Fork flows  over 100 miles through central Idaho, winding through the largest contiguous wilderness area in the lower 48: the Frank Church - River of No Return Wilderness.

Snaking through impressive granite canyons and gorges, including the Impassable Canyon, the Middle Fork drops 3000 feet on its journey to the Main Salmon River. The Middle Fork starts as a small, crystal-clear alpine stream and steadily swells as over 100 tributaries join the river, changing it from narrow and rocky to wide and open. The lower portion of the canyon is characterized by fun, splashy rapids, beautiful pools and swimming holes. The Middle Fork's rapids are categorized as class II-III, except at higher water flows when it increases to class IV.


As the river drops in elevation, it passes through three distinct ecological zones, each with diverse opportunities for wildlife viewing and birding.  Every bend is another chance to see river otter, rocky mountain bighorn sheep, bald eagle, black bear and more.

History buffs will be captivated by the story the canyon has to tell: remnants and artifacts can be found throughout the trip. Pictographs from the Tukudeka or Sheep Eater Indians mark many of the canyon walls, and relics from homesteaders and miners can be found in certain camps.


The Middle Fork of the Salmon is a world renowned, unspoiled cutthroat trout fishery.  From July through September flows offer non-stop dry fly action for anglers of all skill levels.


As if that weren’t enough, the river also offers access to natural hot springs fed by thermal aquifers running thousands of feet deep.  The rejuvenating waters will melt your cares away!
