Course

The creek rises near Castle Peak south of Aspen in the White River National Forest. From there, it travels generally north, flowing along Castle Creek Road and through the ghost town of Ashcroft. Approaching Aspen, the creek flows past the Aspen Music School The creek then goes through the Marolt Open Space. Next it passes under the Castle Creek Bridge in Aspen, which carries Colorado State Highway 82 at the entrance to Aspen. ^[4] It then enters Aspen's Meadowlands Open Space, passing by the Aspen Power Plant and then under a bridge on Power Plant Road. It then continues north a bit to its confluence with the Roaring Fork River. ^[2]
