This is a tiny 'park' within Berkeley, easily accessible by car. The key attraction is a large rock outcropping, which one can climb (not difficult, there are steps put into the stone at places). From the top, very good view across southwest to northwest. With decent visibility it should be no problem to see San Francisco and its bridges. There is a sign explaining that rocks like this one were used by native Indians for gathering and acron mushing. Nice spot to stop on the way, probably not a destination in its own, however pleasant surprise for a neighborhood park.
