The top of Thunderbolt Mountain offers one of the most outstanding 360-degree views in the Helena area. All of the surrounding mountain ranges are visible from the peak. The high elevation and thick timber make this trail one of the last in the region to shed snow, and drifts are common into late June. Near the top, the trail skirts the CDT and recommended wilderness areas where bikes are not allowed, so resist doing any further exploring on your bike.
