Lower bouldering area pretty close to the road. Bring many pads, as some boulders are large with precarious landings.

From Bozeman, park on the east side of the road (left) at large obvious turnout after the Cube area turnoff. Cross the street and locate faint climber's trail slightly south of parking. Follow trail heading north under the power lines. This will lead you in the the direction of the first boulder (Rubbernecker) which will be easy to locate. Follow faint trail system uphill towards main cluster, and some are in the talus field as well.
