Getting wild in a city near you...

This scenic regional park in the Lafayette/Orinda reservoir basin in the East Bay has some of the best trails and views of the surrounding hills and waterways. Spend some time with the many turkeys and cows residing inside the park borders as well as challenging yourself on the rolling hills and fire roads in this amazingly diverse landscape. Come join us and be a part of this event at a Bay Area gem hidden right around the corner from everyone in the Bay Area.
