Marin has a variety of beaches, great for beachcombing, tide-pooling, wave-watching, bird watching, sun bathing, kayaking, and boating. The weather at these beaches can change considerably during the course of the day. Wear layers that you can add and remove as the temperature drops and rises.

Swimming conditions vary by location. Prior to entering the water, please check with park rangers, park personnel, or lifeguards about conditions and always obey the posted warnings.
