Prado

California wrote the book on ghost towns, from Gold Rush tent cities to Owens Valley farm towns the aqueduct dried up.

Prado Regional Park is a 2,000-acre (8.1 km2) park in Chino, California within the jurisdiction of San Bernardino County. It offers fishing, archery, camping, a golf course, horseback riding, and a shooting range, which was the site of the 1984 Olympic shooting events. The park traces its origins to the Santa Ana River floods of 1937 and 1938, which prompted the construction of the Prado Dam in 1939.

The on-the-ground condition of Prado is unverified — it's listed here with unknown status. That could mean standing buildings, or an empty field. Go prepared for either, and consider sharing what you find so the record improves.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.

Here's the honest truth: access to Prado is unverified. We couldn't confirm whether the site sits on public land, private property, or something in between — so verify land ownership and local rules before visiting, and respect private property at all times. The mapped point for Prado is roughly 33.9452, -117.6461 — use it as a starting point and cross-reference a current topographic map before leaving pavement.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.
