Another must-see is PIER 39 for the famous sea lions! We stayed here for probably at least an hour just watching them communicate, swim around, and occasionally fight with each other. It was like nothing we'd ever seen before.
I don't know how they are all okay with being so close together, though. They even climb right on top of each other! They must not know of social distancing.
Tip from Lexi: Speaking of social distancing, if you want to view the sea lions from a space with less people, check out the upstairs area behind and above the more popular downstairs viewing spot. You'll have more privacy, and you can feel safer about taking your mask off.
