If you drive out to the pier, you can get quite close to some sea lions basking in the sun on a nearby floating dock. They are super talkative and interact with each other in between their naps. Drive around the city out to the lighthouse and you can walk around on the rocks during low tide and find hermit crabs, starfish, and snails!
We're glad you got to visit the Harbor when there were a group of Sea Lions in the area. It's fun to watch them try to crowd in on the docks and to hear the chorus of barking from the Sea Lions already on the docks. It's great no-charge entertainment.
