Guatemala City draws visitors whose interests range from Maya history to contemporary culture. Two museums house Maya artefacts, some of which were discovered on a nearby archaeological site; other museums exhibit indigenous and modern art. In Mercado Central, an underground market, shoppers bargain with vendors selling local handicrafts. Additional attractions include a botanical garden and a scale replica of the Eiffel Tower. A night out in bustling Zona Viva caps off a day of sightseeing.

Abandoned in the 10th century, the stunning Mayan ruins at Copan deserve as much time as you can spend there, a full day or more. Travelers recommend that you hire a guide; you'll learn so much more about this World Heritage site and its history and people than you ever could on your own. After your adventure, sip a cup of strong Honduras coffee and people-watch in the main square or just enjoy the beautiful mountain scenery.

Denali National Park and Preserve is most famous for being the home of Mount McKinley, also called Denali, meaning "The Great One." At 20,320 feet, Mount McKinley is the highest peak in North America. The park, which is larger than the state of Massachusetts, has only one road, making it the perfect backcountry adventure. Try to spot The Big Five: moose, caribou, Dall sheep, wolves and grizzly bears.
