The Big Southern Butte is a collapsed cinder cone towering over the desert valley. There are several trails you can use to get to the butte then a great trail that allows you to drive up the inside of the collapsed cinder cone and to the very top. It includes some of the best views in the Yellowstone Divide system of trails.

Cedar Butte is a great adventure for new riders. It has some great steep grades, but they are far easier to ride than some of the more advanced mountain trails in the system and easily avoided if desired. This is a great area for new riders with many enjoyable trails. You can spend the whole day here just minutes from Atomic City.

The Atomic Run is a series of desert trails connecting Atomic City to the St. Anthony Sand Dunes. It is an endurance ride covering apx.180 miles for a round trip. You may choose to team up with another group to have another RV at the host location by the sand dunes to split the ride into two days, but those who complete the ride in one day will claim the honor of completing the Atomic Run.

Past the Big Southern Butte are trails that wind around the eastern boarder of Craters of the Moon. It is unique terrain and there are interesting areas to hike along the way. You may get to witness herds of elk, pronghorn, and other wildlife mixed among the sage brush and lava flows. Bring your binoculars if you have them.

To Hell and Back runs east from Atomic City through the desert north of green farm land and skirting the Twin Buttes to the north. You have the unique experience of riding through the lava flows of Hell's Half Acre east of Shelley and Firth.
