A city park on a grand and wild scale, the 114-square-mile Golden Gate National Parks run up and down the coastline for about 60 miles near San Francisco, hopscotching around private land and incorporating several islands, including infamous Alcatraz.
The recently completed, shoreside Crissy Field bike path begins in the Presidio and rolls across that iconic bridge to the Marin Headlands. Fat-tire riders should turn right there, following multiple dirt tracks along the ridgelines. Skinny-tire types can head left, up Conzelman Road to the 673-foot crest of Hawk Hill. Phenomenal views, serious workout. Blazing Saddles Bike Rentals and Tours, with five locations in the city, rents high-end road bikes ($48$68 per day) and provides ferry tickets. blazingsaddles.com
