Twin Peaks – Mt. Sutro Connector Trail Improvement Project


The proposed project will formalize a trail from Twin Peaks Blvd. to Mt Sutro via Marview Way, around Sutro Tower, on to La Avanzada St. and then Clarendon Ave. TP_Mt Sutro trail primaryThis proposed connector would follow the unofficial paths currently frequented by pedestrians and bicyclists. Our hope is to organize trail volunteers for a work day in Summer of 2016 to formalize this trail connector.

This is a jiont partnership between the SFPUC and Rec and Park.
