If you are coming to southern Idaho to ride, this spot should not be overlooked. With over 50+ miles of designated ATV trails, twisty mountain single track, secluded swimming holes, cool camping spots and scenery ranging from high desert rolling hills to rugged, forested mountain and canyon views, there is something for everyone.

Most of the trails are marked and form both short and long loops. Camping ranges from primitive tent sites to designated campgrounds. Bear Gulch, Porcupine Springs, Bostetter and Father and Sons campgrounds cater to the ATV/side by side crowd while motorcycle riders will find direct access to single track at Harrington Fork (day use only), Third Fork and Fifth Fork trailheads.

Most campgrounds are free but are on a first come basis. Porcupine Springs, Lower and Upper Penstemon Campgrounds charge a small fee but can also be reserved.

Off road vehicles must display a current Idaho OHV Sticker. Note that this trail system is also very popular with mountain bikes and equestrian riders, so use caution.

ATV and UTV riders can access South Hills if staying in Jackpot by using the BLM access roads that are found on the outskirts of town and head in a northeast direction.
