Buena Vista Park is a small but dramatic park above Haight-Ashbury.
I usually start at Buena Vista Ave and Upper Terrace. Walk up the large path which meanders to a small lawn at the top of the park.
From the lawn walk down through the maze of paths. It's a densely wooded park but every time you walk round a corner you're treated to a different city view peeking through the trees.
