Discover the pastoral beauty of Chile’s Chiloé Archipelago and lose yourself in the charming villages on Chiloé Island, where the port of Castro is the largest town and island capital. Here you’ll find one of the 16 wooden churches built by Jesuit and Franciscan Catholics from the 17th to 19th centuries that together compose a UNESCO World Heritage site. Castro is also fairly close to Chiloé National Park, where you can find hiking trails to suit all levels of fitness. If you want to load up on carbs before you go, be sure to have some potatoes – varieties grown on Chiloé Island are among the oldest cultivated tubers in the world.
