Spread out across the Continental Divide, the areas covered offer a wealth of climbing opportunities with everything from roadside crags, to the best back country spires in the state, to vast and largely untapped bouldering fields. Long popular with locals from Butte, Missoula, Bozeman and Helena, the Boulder Batholith is scattered near the arteries of Interstate 90 and Interstate 15; offering an easily accessible 'stop-over' for road-tripping climbers from Alberta or from across the US headed south to the desert, north to Canada, east to Devil's Tower, or west to the Cascades.
