Sibley Volcanic Regional Preserve, Oakland, California, USA



Not too far from the University of California, Berkeley is Sibley Volcanic Preserve.  This Preserve in the Oakland Hills features Round Top, a peak consisting of lava and volcanic debris left over from an ancient 10 million year old volcano.

There are many trails in Sibley, some are part of the Skyline National Recreational Trail and Bay Area Ridge Trail which connects to Wild Cat Canyon and Chabot Parks.  A Backpackers’ Camp is located near the Overlook Trail. A 2 mile loop trail starting at Overlook Trail led us to the labyrinths, where my kids enjoyed circling the rock puzzles. There are a few labyrinths, the ones we found are located in or near the quarry pits.

About 3 mile loop trail takes you from the start of the Overlook Trail to the end of the Volcanic Trail and back via the Overlook Trail. If planned correctly, you could enjoy the labyrinths on your way to the Volcanic Trail. Our challenge was always peeling our kids off the labyrinths to continue on. There is a self-guided trail brochure at the start of the trail that explains the sights along the Volcanic Trail. Wide open spaces and cow grazing areas greeted us for most of our hike.

Geocaching took us to a hill where we saw Golden Gate Bridge from one side and Mount Diablo from the other.  Unfortunately we did not find the cache we were looking for. As of January 2016, there was no parking or dog fee at Sibley. Look out for pullouts when driving down from Sibley for views of the Bay Bridge and Golden Gate Bridge.  It was quite a sight to see on our way down around sunset.
