Clayton
Clayton, California
Half a day is enough for Clayton: walk Main Street, visit the museum, then hike in Mount Diablo State Park. Not a base.
Clayton is a small East Bay town at the foot of Mount Diablo, best as a half-day stop or a quick dinner detour. Its main draw is the mountain park; the town itself has a short historic Main Street, a local history museum and a couple of well-regarded pizza and sports-bar spots. Most travellers use it as a lunch or hike stop between Concord and the park.
