Docent Naturalists Olga and Tony Bright look forward to sharing both the rich history and the diversity of plants along the Bridle and Schilling trails in this smaller preserve. Even on a midsummer’s afternoon day, the trails tend to stay cooler since you’ll be hiking beneath the redwood canopy. Though this exploration is moderately-paced, there are a couple of steep inclines. Reservations are required and will be accepted on or after June 27 at 12:00 p.m. (Noon) and close July 10 at 2:00 p.m.

Where to Meet

From highway 280, follow Sand Hill road until it becomes Portola Road. Turn right onto Old La Honda Road and you'll get to small turn out parking area at Dennis Martin Creek. Parking spaces are very limited. Carpooling is highly encouraged.
