What It Is

The county describes a combined 4,600-acre sanctuary with more than 15 miles of trails, including “over the river and through the woods” loops. The page mentions a new Nature Center but gives no hours for it. Source: San Diego County Parks, read 2026-10-23.

Creek Safety

The county asks: “For your safety, stay on trails and avoid playing in the creek.” The page does not name the creek, so we do not name one here.

Fishing

The county page does not mention fishing. Treat fishing here as unconfirmed and see our stream fishing rules for the state license rule.
