Next time you go on vacation, forget the taxis, the rented cars, the buses and the trains, and just borrow a bike. Park Hyatt hotels around the world will soon be offering their guests free bike rentals for up to four hours at a time so you can tour your foreign city the leisurely, healthy, and environmentally conscious way. The brand's Bicycle Valet program begins Aug.1, so if you’re planning a getaway, leave your cares and your cars behind.

Of course, you don’t have to wait until you arrive in a new, exotic locale before you go biking. Whether you’re trying to ease your commute or keep in shape, the Green Life offers great tips for bicycling right in your hometown.
