Estero Bay

Estero Bay is our gorgeous 15-mile bay situated in Los Osos/Baywood, Morro Bay and Cayucos. The calm waters are a home to many marine mammals, fish, birds and wildlife that are rarely seen in other parts of California. Our bay gives visitors a chance to see marine life up-close in their natural habitats.

Where the Whales Are

The whales are typically seen right outside of the bay in the ocean waters. The bay is too shallow for bigger species like whales, however you will be able to see other marine mammals. Sea otters and harbor seals are regularly seen in the bay next to the haborwalk across from the smoke stacks. A group of otters typically plays out next to Morro Rock as well. This is the best lookout for otters. Harbor seals are also visible from the Rock -- the seals typically gather on a floating dock in the bay.


Gray whales are present mid/late Dec through April.
Humpback whales are here April/May through October.
Otters and seals are here year-round.
