Located not far from the Castro, Buena Vista Park has lots of trails and paths with plenty of trees and hidden spots. You'll find a mixed crowd here, but mainly 35+ and not so many younger guys. Popular with the early morning dog walkers, the lunchtime crowd and also into the evening. The cruisiest spot is at the top of the hill looking out towards the city. It's quite a steep park, so it's not wheelchair friendly, but is generally quite safe. If you see the Police driving around, just walk away from their headlights.
