Paddling Around the U.S.

Tomales Bay is a gorgeous 15-mile strip of water just north of San Francisco in Marin County, California. There are several launching points along the bay, but an especially cheap option is Lawson's Landing, where you can get a boat for $10 and go clamming, fishing, or just splash around. Keep an eye peeled for wildlife — whales often migrate past the bay, which is home to no small number of sea lions. Other kayaking options are available on Marin County's website.
