Castle Rocks State Park operates Smoky Mountain Campground through Idaho Parks and Recreation, providing access to both the state park and nearby City of Rocks National Preserve. The campground sits above the valley with elevated views, reached by a 7-mile drive from the City of Rocks entrance. Pets are not permitted at this facility.
Sites spread out along a paved loop road with substantial spacing between neighbors. Most spots are back-in configurations with 30/50 amp electrical service and water hookups during the operating season. Fire rings and picnic tables come standard, while medium-sized pine trees provide natural barriers between sites. Kristin S. notes the campground has "very private and nicely spread out" sites with "great views of City of Rocks."
The facility includes clean restroom buildings with individual shower rooms and handicap accessibility. A dump station operates about one mile toward the park exit, though seasonal closures affect water services from roughly November through April. During winter months, campers rely on pit toilets located in the equestrian parking area. Cell service runs limited, with Verizon providing 3G coverage according to visitor reports.
Rock climbers find extensive opportunities at both Castle Rocks and City of Rocks, while hiking trails connect directly from the campground to surrounding areas. The small town of Almo sits 1.9 miles away, offering Tracy's General Store for basic supplies, meals, and locally made ice cream. Amanda T. appreciated "the paved roads were great for bike riding" around the campground loop.
Reservations prove challenging during peak climbing season, and the campground sits 40 miles from major highways. Those seeking additional options can explore campgrounds near Almo or check nearby alternatives like City Of Rocks RV. The elevation of 5,567 feet provides cool evening temperatures even during summer visits.
