In this grossly overcrowded urban environment, finding a safe and relaxing place to wander off on a meandering weekend bicycle jaunt without having to fight cars, dog-walkers, joggers, rollerbladers, skateboarders, and too many other bicyclists is nigh impossible. Fortunately there's a place that'll give you all this, plus a chance to see what a beautiful place the bay was before 19th-century Eurotrash ruined everything by civilizing it: The Alameda Creek bike trail. The creek is the longest natural running waterway in the East Bay, coursing nearly twelve miles from Niles Canyon to the bay. To ride it, take BART to Fremont and trundle down Decoto Road to the Alameda Creek trail crossing, heading toward the bay. While some of the creek wanders through suburban neighborhoods, you're out of automotive reach, and once you've entered Coyote Hills and the salt marshes of the Don Edwards San Francisco Bay National Wildlife Refuge, you will no longer see or hear any signs of modern civilization. This is the East Bay as it once was: truly beautiful.
