At its westernmost point, Kelly Canyon starts at the Kelly Canyon Ski Resort at the Caribou-Targhee NF border. This long trail briefly leaves the national forest, crossing into Idaho Dept. of Lands territory before dropping back in as Long Hollow Road. Plentiful dispersed camping is available with a 5-day limit. The road is easy and well-maintained. Long Hollow Road can even be taken all the back to Highway 33, east of Rexburg.
