Thunder Mountain Loop — 25 Mile in the Wild Idaho Endurance Challenge

Wild Idaho Endurance Challenge · Central Idaho

Thunder Mountain Loop — 25 Mile

- ~25 miles, ~5,300 ft climbing

"This route still gives you a great taste of the remoteness of the RONR wilderness, but you do miss the best part of the 50 mile route, which is the long Lookout Ridge section once you climb up after fording Big Creek. You do, however, avoid the Big Creek ford. You will still pass by the old Lookout Mountain fire lookout site."
