Crissy Marsh station

From the Marina, walk west along a well-developed portion of the San Francisco Bay Trail and you’ll soon pass Crissy Marsh, a unique ecosystem with a diverse species of migratory birds, plus local harbor seals and sea lions along the beach. Beautiful nature walk, and you can keep going clear up to the Golden Gate Bridge. A nice walk anytime of day, but sunset is wonderful. Go at high tide and you might catch harbor porpoises surfing in. After 60 years, they’ve returned to the bay because of improved environmental conditions.
