Fort Ord Dunes State Park is a state park located in Marina, California, on the former Fort Ord military base. Fort Ord was established in 1917 as a U.S. Army training facility and was used for several decades before being decommissioned in 1994. In the late 1990s, the state of California acquired a portion of the Fort Ord land and converted it into a state park.

Fort Ord Dunes State Park is popular with locals because it has the longest unbroken paved bicycle and walking trail in Monterey County. Handcar Tours operates handcar and rail bicycle guided tours through the scenic park. One unique aspect of the park is that it contains some of the last public accessible Coastal sand dunes in California.
