A trip to Patagonia will have adventurous paddlers cruising past gigantic glaciers and some of the most stunningly beautiful landscapes on the planet. The Marble Caves out in in the turquoise waters of General Carrera Lake sit 5,000 million tons of marble, elegantly shaped by nature into caves. Viewing the caves in person is a far more beautiful experience than looking at any photo. Also, this is one of the best SUP destinations in the world for extreme paddlers.
