The majority of this trail is singletrack full of river rocks and occasional sand pits. You will run into a few wider fire roads. The climb is gradual and can be very technical in spots. The first part runs parallel to the paved Cucamonga Creek Trail until you hit the Dam. Then you enter the Cucamonga Canyon Wash. The trail continues on the east side of the wash and gets less rocky as you reach the connecting Dam. Once you cross on to the west side there is another entrance leading to a very fun and technical rocky trail. You take this one until it crosses back over to the East side. It can be ridden to connect to The Cucamonga Road Trail . Turn back and ride this roller coaster of a trail the same way you climbed it. Super fun and fast.
