Several hiking trails are maintained on the property and connect to trails in Leonard Park and other local preserves. See detail trail map here. The Sanctuary was established in 1956 as an 11 acre parcel. It has grown over the years through the addition of a series of other parcels. See the sanctuary history here. Four parking areas provide access to the trail system and the gardens / amphitheater at Brookside. The Marsh Sanctuary is host to a community garden and a number of other projects focused on sustainable living. Find out about the community garden here.
