Walk on a Glacier in El Calafate, Argentina
The Patagonian Ice Cap is the largest stretch of non-polar ice on the planet, and Perito Moreno is its crowning jewel. This 19-mile-long chunk of baby-blue waves frozen in time is one of the most spectacular and accessible glaciers on the planet. The best way to explore it is by strapping on crampons and climbing aboard. The glacier is moving downhill, but at a rate of 2 meters per day. Several outfitters offer half-day and full-day ice hikes from El Calafate, all of which begin with a boat ride across the glacial lake from Puerto Bajo de las Sombras.
How to get here: Fly to El Calafate's Comandante Armando Tola International Airport (via Buenos Aires) and book a tour in town.
