I liked this section because it wasn’t on the side of the hill as much as some of the other trails. That said, there are plenty of rocks and roots and features. I rode down from the main parking lot and enjoyed the flow. The lowest section looked like it would be very wet in the rain and is very eroded, the trail is now along side a wide ditch from the runoff. Careful if it’s wet.
