From March 1 through June 30, Drakes Estero is closed to protect the breeding colony of harbor seals. The closure applies to kayak and canoe usage but is applicable to any other water sport users around harbor seal colonies in the area.
The east side of Hog Island in Tomales Bay is also a land resting area for harbor seals year round. Visitors are asked to stay at least 100 yards away from resting seals. Never pick up a seal pup that may look abandoned. Although they may appear abandoned, they are most likely waiting for their mother to return. Pups are about two feet long and weigh about 25 pounds and are weaned at 30 days.
