Lemhi Pass, also known locally as Agency Creek, climbs from the Lemhi Valley to the Lemhi Pass through the Salmon National Forest. The mostly wooded drive follows Agency Creek to the Continental Divide. Water on the east of the divide flows to the Atlantic Ocean. Water on the west ends up in the Pacific. The road is fairly tame except for the very steep climb of the last two miles. RVs and trailers are not recommended, but almost any other vehicle could drive the trail.
Agency Creek Campground is about 4 miles from the lower end of the road. It is free, can accommodate multiple vehicles, and has pit toilets, fire pits, and picnic tables. It sits beside the creek. There are also multiple dispersed campsites higher up the trail.
