The best parks for fit travelers

In honor of the National Park Service turning 100, rangers share their favorite ways to stay fit in the great outdoors.

Later this summer (August 25, to be exact), the U.S. National Park Service officially commemorates its one hundredth anniversary. But the centennial celebration has been going on all year with a record number of visitors road tripping and exploring the 400-plus parks throughout the country—including the Obama family, who traveled to Carlsbad Caverns and Yosemite National Park earlier this month. And because visiting a national park usually involves some form of physical activity (hiking, kayaking, biking...the list goes on), we asked a handful of park rangers for their favorite fitness activities in their parks.
