Frequently Asked Questions
How does the Main Salmon permit compare to the Middle Fork?
The Main Salmon is generally less competitive than the Middle Fork — 8 parties per day vs. 7, and a smaller applicant pool. Still a wild trip through one of the most remote river canyons in America.
How long is the Main Salmon trip?
The core private section from Corn Creek runs approximately 79 miles to Long Tom Bar, typically completed in 5–7 days. Max party size is 30 persons, with trip length decreasing as group size increases.
When do Main Salmon permits open?
Through the same USFS "4 Rivers" lottery on recreation.gov as the Middle Fork. Control season runs approximately June 20 – September 7; outside this window, permits are first-come rolling.
