19 mi, 5 M, 2600 ft; Alum Rock Park Mnt,Sierra Vista

Starting at the Berryessa Community Center, we'll ride to Alum Rock Park and then climb up the Alum Rock trails to explore the upper part of Sierra Vista including the Upper Calaveras Trail and then return. There are no facilities once we are on the trails, so plan to be self sufficient. There are great views from the top, weather permitting. Be prepared for cold temperatures at the top. The route may be modified based on trail conditions. Note the later than usual start to let things warm up as we switch to standard time. Start location: Berryessa Community Center [Route/Map]
