About

Overview Lower Penstemon Campground is located along the scenic Rock Creek Road, in southern Idaho, at an elevation of 6,600 feet. Visitors come to the area to enjoy its abundant trails and natural beauty. Recreation Hiking, mountain biking, horseback riding and off-road vehicle trails crisscross the surrounding area. Third Fork, Pike Mountain, Rim View and Porcupine Spring trails all begin nearby. Rock Creek runs along the campground, offering good trout fishing. Facilities The campground contains single-family campsites with picnic tables and campfire rings. Vault toilets and drinking water are provided. Roads and parking spurs within the campground are gravel. Because the campground is situated along the main road, some noise from passing cars is to be expected. Natural Features The campground is situated in a mixed conifer and aspen forest, just off Rock Creek Road. Most sites have partial shade. Summer wildflowers dot the landscape and wildlife can be seen frequently in the surrounding area.
