This is a fabulous trail! It was designed and built by the same team that built the flow trail in Tamarancho Boy Scout camp in Marin, CA.
Starting at the end of the easy singletrack ascent of the Soaring Eagle Trail, look for the picnic table and water tank at the top of the hill. The entry is through a gate just behind the paved area.
The trail has many small, jumpable, bumps, some table tops and lots of curvy banked turns. It is pretty exposed in spots, but the bumps can be rolled over by intermediate riders safely and jumped crazily by those that are so inclined.
The trail runs out on a flat section to the bottom of Big Valley Trail, so you can climb back up and do it multiple times.
