Crockett Hills is an excellent mountain biking park. There are great trails through the woods and over the hills with awesome views of the Carquinez Strait. This loop ride takes you to the newly created (as of 2014) and as yet unnamed pump/flow trails on the back side of the park.
Start at the Crockett Hills Regional Park staging area off of Crockett Boulevard. At the end of the parking lot, you'll find a gate and the trailhead.
Go left at the gate for about .4 miles then turn right to go up the singletrack portion of Edwards Loop Trail
". Follow the gentle, shaded singletrack ascent through the forest. At the top turn right and go a short distance to reach the tunnel that goes under the Cummings Skyway.
Go through the tunnel to reach the grassy hill area of Crockett Hills. Go straight on the Soaring Eagle Trail
. It is all singletrack. The views are amazing. Plan time to take pictures. In the summer, this trail can be very hot or very cold and windy. Plan for both. The Soaring Eagle Trail
follows the contours of the hills gently ascending to a paved area with a picnic table near the intersection with Big Valley Trail
From the picnic table, go through the gate to enter the new Pump/flow trail (Sugar City Trail
). The trail descends about 500 ft with lots of bumps, jumps, berms, tabletops and switchbacks. It's safe enough for intermediate riders and exciting enough for experts. The trail was designed and built by the same folks who built the Tamarancho trails.
Follow the traverse out of the pump/flow trail until it intersects the Big Valley Trail
. Continue on to Krestrel Loop Trail until you reach the small farm building. Turn right on South Tree Frog Loop
. This is a short, steep fire road that will take you to the top of Flowetry In Motion in about 1/3 of a mile.
Turn left and follow the flowy Flowetry In Motion trails bumps, banked corners and gratuitous curves to for a couple of mile until it turns into a farm road by the creek, North Tree Frog Loop
. Watch for uphill traffic (sight lines are generally pretty good).
Follow North Tree Frog Loop
back to Big Valley Trail
. Turn right and follow Big Valley Trail
by the creek and then UP to get back to the beginning of Bump and Jump Trail. When you get back to the top retrace you path on Soaring Eagle trail to get back to the tunnel.
Instead of going back down Edwards Loop trail, go right and stay right to take Wood Rat and then Edwards Creek trail to experience yet another gorgeous singletrack through the woods. You'll end up on the last section of Edwards Loop trail that will take you back to the parking lot.
