1. Presidio Tunnel Tops
What is it: An expansive new park opened in 2022 on top of the Presidio Parkway highway tunnels, connecting the Presidio to the Crissy Field waterfront—designed by the same people behind New York's High Line.
Why go: The 14-acre federal parkland offers tons of green space by the water and is now one of the best spots to take in views of the Golden Gate Bridge. If you have kids in tow, they'll love the Outpost, a natural-themed playground, and the Field Station, where they can draw butterflies, discover maps and get hands-on with science.
