Del Valle Regional Park
This park is closer to Livermore than Pleasanton but is still well under an hour's drive from anywhere in either city. At the center of this EBRPD park is Lake Del Valle, but there are several beautiful rock formations in the park as well. There are scores of miles of trails in the park that go through the hills and mountains surrounding Lake Del Valle, and the park works as a gateway to the Ohlone Trail, which leads in the direction of one of the Bay Area's most popular climbs, Mission Peak.
