The long-isolated island village of Raúl Marín Balmaceda finally has road access and it's well worth the detour. At the mouth of the Río Palena, a watershed preserve, it's teeming with wildlife such as otters, sea lions and Austral dolphins. For the best marine life, paddle out in a kayak or take a boat tour. The village has wide sandy streets and grassy paths to a lovely beach.
