If COVID doesn't get worse, I have plans to visit San Francisco, and while there, I definitely want to pay a visit to all three of the city's animal attractions (San Francisco Zoo, Aquarium of the Bay, and the California Academy of Sciences) as well as going on a boat tour to the Farallon Islands to see the local marine life. For those who've been to San Fran, what would be your tips and recommendations for visiting these places?
