Castle Rocks State Park, a former ranch, is Idaho’s newest state park, located adjacent to the City of Rocks National Reserve. Its 1440 acres includes similar outstanding rock formations, early 20th century ranch structures and pastures. Facilities are still in development but recreational opportunities include rock climbing,photography, picnicking,wildflower viewing, hiking, horseback riding, snowshoeing, mountain biking, and superb birdwatching.

The 1,240-acre ranch includes examples of early 20th Century ranching structures, irrigated pasture and striking scenery. Some spires rival nearby City of Rocks National Reserve, and offer exceptional rock climbing. Other recreational opportunities include picnicking, hiking, equestrian trails, and wildlife viewing. Mule deer, mountain lion, bighorn sheep, and the state’s first recorded ringtail are found here. Bird watching is superb, with nesting populations of common snipe, sandhill crane and sage grouse frequently encountered.

The park also protects some of the most pristine archeological sites in southern Idaho. Evidence suggests that Castle Rocks was favored by different cultures over the previous 2,470 years. Portions of the park are included in the City of Rocks National Historic Landmark.

With hundreds of routes to explore, the challenging landscape of Castle Rocks State Park attracts rock climbers from around the world and provides superb hiking, mountain biking, and horseback riding in the midst of a dramatic backdrop that dates back 2.5 million years. Remnants of Native American pictographs, historic trail crossings, and 20th century ranching are visible in the park today.

Evidence suggests that folks have been coming to Castle Rocks for nearly 9,000 years. Campsites are nestled among Idaho’s largest pinyon pine forest on the east slope of the 7,500-foot Smoky Mountain.
