The exclamation mark on San Francisco's skyline is Coit Tower, with 360-degree views of downtown and wraparound 1930s Works Progress Administration (WPA) murals glorifying SF workers. Initially denounced as communist, the murals are now a national landmark. For a wild-parrot's panoramic view of San Francisco 210ft above the city, take the elevator to the tower's open-air platform. To glimpse seven recently restored murals up a hidden stairwell on the 2nd floor, join the 11am tour Wednesday or Saturday (free; donations welcome).
