Marshall Canyon Regional Park offers a more rustic hiking experience, with winding single-track trails shaded by ancient oaks and sycamores. Recommended by the Inland Valley Daily Bulletin and local hiking groups, this lesser-traveled network sits just north of Ontario and is managed by Los Angeles County Parks. The area is renowned for its peaceful ambiance, occasional deer sightings, and the diversity of its plant life. Community events and stewardship programs further root the park in the local culture, making it a cherished resource for those seeking solitude or a quiet escape from the city.
