San Francisco: Muir Woods Bus & Golden Gate Bridge Bike Tour

Depart from Fisherman's Wharf and cross the Golden Gate Bridge by shuttle to the redwood canopy of Marin County. Spend 75 minutes in Muir Woods National Monument, home to some of the tallest trees on Earth.

Afterward, ride to the bayside town of Sausalito. Spend some free time here before returning to San Francisco for a bike ride.

In the afternoon (or another day), hop on a bike and ride along the Bay Trail. You'll start at the Embarcadero and pass by the Ferry Building and Presidio of San Francisco, then ride across the Golden Gate Bridge.
