The South Hills, located just south of Twin Falls, Idaho, is a notable off-road destination with over 50 miles of designated ATV and single-track trails. The riding experience is highly varied, with terrain that transitions from high-desert rolling hills to rugged, forested mountains and canyons. The trails are suited for a range of skill levels, with options for both casual rides and more challenging, technical single-track routes. The area is also known for its secluded swimming holes and cool camping spots.
The trail system is on BLM land and is accessible from multiple trailheads, including the Indian Springs trailhead, which is a common starting point for a popular eight-mile loop. The area is primitive, and riders should be self-sufficient as there are no services like trash, water, or restrooms. All riders must have a valid Idaho OHV registration sticker.Dirt Bike Trail System
