The ‘60s and ‘70s in San Francisco were synonymous with psychedelic “hobbies,” but tripping in the new millennium on Pier 39 is something you can now enjoy, legally, with the entire family. This labyrinth of 77 mirrors and black lights is reminiscent of a carnival fun house, and finding your way out of the 2,000-square-foot kaleidoscope of glowing twists and turns and befuddling dead-ends puts the fun in funky. While ‘80s music thumps, kids race through and into the walls, while adults feel their way down endless neon hallways. Created by Charles Magowan (who, no surprise, studied psychology at Yale), the Mirror Maze is a trip for all ages, and at just $5 it might be the cheapest one you’ll find in San Francisco.
