Just getting to Marenco means the excitement of flying by small plane, cruising by boat down a tropical lowland river, and crossing the open ocean. Once there, you can hike in the forest, explore deserted beaches, snorkel the rock and coral shores or go horseback riding. Even deep sea diving can be arranged. There are also boat tours to nearby CaÒo Island and Corcovado National Park, a rainforest reserve of global significance and one which adjoins Marenco's own 500 hectare reserve. Simple thatch roofed cabins sit in a small clearing by the rainforest edge, atop a high promontory. Viewed from every balcony, Marenco's endless sky and the Pacific Ocean spread out below in an ever-changing panorama of light and motion. From these heights, ponderous Humpback Whales can often be seen braking the surface of the water in their season of migration. With quiet patience your should see dozens of bird species, monkeys, sloths, coatimundis and much more. Jaguars, pumas and other big cats live here, too, but are much too secretive to reveal themselves to the casual observer.
