The landscape around Martinez is defined by low rolling hills meeting the tidal Carquinez Strait, which has shaped both waterfront development and the local economy. On the strait’s south shore, the city occupies a key waterway linking San Francisco Bay with the Sacramento–San Joaquin Delta. Martinez is the county seat of Contra Costa County, with a historic downtown near rail and waterfront routes. Naturalist John Muir spent the final decades of his life here; his former home and orchards are preserved at the John Muir National Historic Site. The Martinez Marina provides access to the broad, working shoreline of the strait.
