Hotel Monasterio, Machu Picchu, Peru
Perched high in the Andes, the ancient city of Machu Picchu is the New Age Mecca--one of the most beautiful and spiritual places in the world. Originally built as a monastery in 1592 on the site of Inca Amaru Qhala Palace, Hotel Monasterio in the town of Cusco (three hours by train to Machu Picchu) is an ideal spot for honeymooning. A stunning chapel is also available for weddings. But be warned: It's not a trip for the faint-hearted. The traditional trek by foot to the ruins is a four-day walk through altitudes that will test the healthiest lungs. But by all accounts, it's worth it.
