18. Capulin Volcano, New Mexico( Tobias via Flickr )
Right on the border of Colorado near Des Moines (not to be confused with the Iowa capital), the extinct Capulin Volcano rises more than 1,000 feet above the surrounding plains. Visitors can climb the two-mile paved road to the top, which sits at 8,182 feet, and walk around its rim. The volcano is 261 miles from Albuquerque. Summers are mild, but thunderstorms are common in July and August. Winter blizzards may temporarily close the park.
Visitors in 2009: 50,935
