Big Ditch Trail is mostly doubletrack with some spots where it narrows down to singletrack. The trail surface is hardpack with a few rocks and roots. The trail is really fun and fast in either direction- just a magic carpet ride! The trail can experience mud when it rains and is pretty exposed, resulting in slick ice/snow if its cold enough.
This trail is very popular with hikers, dog walkers, and runners.
