Bothin Marsh Preserve

Highlight • Natural

This 106-acre preserve incorporates a 2-acre tidal wetland that’s a small reminder of the vast salt marshes that once surrounded San Francisco Bay. A quiet inlet at the north end of Richardson Bay, surrounded by cordgrass and pickleweed, it’s home to several endangered species and many shorebirds and waterfowl rest and feed here. The Sausalito-Mill Valley bike path, and the branch to Tennessee Valley/Mt Tam, are paved through the marsh.
