Mountain Biking Safely in Regional Parks

Wednesday, Nov 2, 2022

There are many opportunities for biking in Regional Parks, with over 800 miles of dirt roads and approximately 50 miles of natural surface trails that allow bikes. However, biking is only permitted on some designated narrow trails. Here is some information on bike-friendly narrow multi-use trails in the Park District.

Crockett Hills Mountain Biking Flow Trails
Crockett Hills Regional Park features 10 miles of narrow bike-optimized multi-use trails where mountain biking is allowed. There are also two designated bicycle loop trails, one short and one long, that traverse oak woodlands, hillsides, and ridgelines and offer views of San Pablo Bay, Carquinez Strait, and Mount Diablo. Bike bells are recommended and provided at the trailhead. 

Crockett Hills flow trails include the Edwards Loop Trail, Wood Rat Trail, Soaring Eagle Trail, Warep Trail, Two Peaks Trail, Goldfinch Trail, Tree Frog Loop Trail, and Sugar City Trail. The Goldfinch Trail is subject to seasonal closure.

Tips for Bikers

The most important action you can take when biking is knowing the rules, including the approved speed limit and what to do when passing others. When biking, keep the following in mind: 
• Slow down around others, stop if necessary 
  – Slow down to pass safely. Pull over and stop, if necessary, when there is not enough room to pass safely. 
• Call out or ring your bell when passing
  – To avoid surprises and collisions, call out “on your left” or “on your right” and/or use your bike bell to alert others of your presence (within 50 feet).
• Always yield to pedestrians and equestrians
  – As bicyclists typically travel faster than other trail users, be cautious and give others the right of way. Be extra careful when approaching other trail users from behind.
• Stay on designated trails for your safety and others
  – To ensure safety, bicycles are only permitted on designated sections of narrow trails (see above).
