This fun, free Zoom tour, sponsored by Greenbelt Alliance and led by Bob Johnson, features 7 rock parks centered on large volcanic rock outcroppings (shown, Contra Costa Rock Park). Bob leads us along delightful pedestrian paths and stairways to enjoy fine vistas and quintessential North Berkeley neighborhoods, with lovely gardens and architecture. The actual walk is 5 miles roundtrip with 1,100 feet of elevation gain, but Bob covers it all in 1 hour in this virtual tour. Rock Parks of Berkeley is one of 21 walks featured in Berkeley Walks, co-authored by Bob and BPWA board member Janet Byron. Sign up for the free tour on Eventbrite.
