Big Southern Butte

From Arco: Take the Country Road/300 North heading south (this is signed as the 'Arco OHV Route'). Turn east onto Arco-Minidoka Road/2930 North. Turn onto 2900 West heading south and turn west onto 2150 North, turn north onto 300 West which turns into 2225 North. Turn onto the Arco-Minidoka Road heading south for several miles. Turn east onto Quaking Asp-Frenchman Road toward Big Southern Butte. At Frenchman's Cabin, turn and head up the Butte. From Idaho Falls/Pocatello: Take Highway 26 to Atomic City. Follow Main Street/Taber Road about 1.5 miles south and turn right onto a gravel road (W 1600 N). This semi-improved road passes around the north side of the Butte until it reaches a small landing strip, which was also an old stage coach stop. Turn and follow the road uphill. There is a place to park by the side of the gate if hiking.
