CONTRA COSTA COUNTY, California. Contra Costa’s varied terrain stretches from urban San Francisco Bay shores to Mount Diablo and the Sacramento–San Joaquin Delta. California58 selected these destinations for their mix of culture, landscape and local identity, not because a sponsor paid for placement.
This guide serves both first-time visitors and long-time residents looking for a more thoughtful way to explore their own county. The initial list is an editorial selection, not a published community vote. Check access, charges and hours directly before departure.

Build a trip that works
Do western-bay history and the eastern Delta on separate outings; crossing the county in rush-hour traffic takes time. If you have one day, start with Mount Diablo State Park, then consider Martinez downtown and waterfront if road conditions and timing permit. For a longer stay, add John Muir National Historic Site and explore local businesses rather than rushing between distant stops.
