Trail is relatively flat. A few small climbs and fun little up and downs but overall little elevation change. Trail is very well marked and broken in from high mountainbiking trafic. the trail is riddled with small rocks (up to 12 inches in width/length). The trail tends to be very busy during the weekend. I usually like to catch it early in the morning during the week. The trail is approximately 9 miles out and 9 miles back Good cardio workout.
