It's no secret that spending an hour or two surrounded by trees and plants can increase your energy. If wandering around town has worn you out, Bayfront Park is a perfect spot to relax and recharge your batteries.
When you've finished at this recreation and green space in San Francisco, why not make your way to Hillsdale Shopping Center, Crystal Springs Golf Course, and Coyote Point Park? They're close to Bayfront Park and also popular with tourists.
