San Francisco 39 is a very busy tourist attraction, also known as Fisherman's Wharf. There are two main attractions: cruise ships and aquariums. It takes about an hour and a half by boat. It can pass through the Golden Gate Bridge, Angel Island, Devil Island and other places. Everyone will have a headphone cable to listen to the Chinese explanation. It's very detailed. It's all along the way. We didn't go to the aquarium. The poudin restaurant is recommended for dinner, where the seafood soup is delicious.
