San Francisco by Megabus

The Megabus makes its way over the Bay Bridge from Oakland en route to San Francisco as the sun begins to rise in late August. For just a buck, passengers can take this cozy bus ride to San Francisco, where they can enjoy Alcatraz, cable cars, chowder and more. The linchpin of this penny-pinching tour is Megabus.com, which launched its California operation in early August. Some adventurous types might even turn this into a whirlwind tour, returning to Los Angeles in 24 hours.
