Use the great outdoors to get healthy and fit. On an active vacation, nature is your playground. As more people seek different ways to make a vacation special, the trend of mixing downtime with more than lounging on a beach is gaining popularity. Nothing beats being upfront and center with a destination. Active vacations range from exploring classic locales by bike to venturing off-the-beaten-track while race running through Alaska. Often a change of scenery is the best motivator for just getting out there.
