- The paved road quickly becomes a steep unpaved road. Stay on the main road. The road switchbacks across the front of Aspen Mountain and reaches Gwynn's Restaurant (open only during ski season) at approximately the 2 mile mark. The steep switchbacks continue, passing under and to the right of the gondola. The road reaches the Sundeck Restaurant at the top of Aspen Mountain. There are spectacular views in all directions. From the top, you can access Richmond Hill Road (which follows the ridge behind Aspen Mountain), or Little Annie and Midnight Mine Roads. Automobiles are not permitted on Summer Road for recreation purposes.
