The Community Ditch Trail is an easy mountain biking route that serves as a connector to the Marshall Mesa trails. While not particularly thrilling to ride, it offers beautiful views of the Flatirons and golden open fields. The trail effectively connects the east and west sections of trails across Highway 93, making it useful, scenic, and straightforward.

Gross Reservoir is a large lake on the other side of Flagstaff Mountain. There is a hard-packed gravel road on it's eastern shore which is a great place to snap a few photos after the tough climb up Super Flag and long descent down. If you are unwilling to take you bike on gravel, however, you still get great views of the reservoir and the surrounding area at the junction on the pavement.
