We’d heard that Manuel Antonio was one of the best places in the country to see sloths. Having already been spoilt with our sightings so far, our bar was set pretty high. Our guide Danny took us on a tour through the national park itself and, while the results were slow to begin with, by the end of the afternoon we’d seen dozens of capuchin monkeys, bats, howler monkeys, squirrel monkeys and, miraculously, three sloths. We saw innumerable birds too, although not as many birds as we saw the next day when we kayaked through the mangroves at nearby Damas Island. It was an immersive, up-close experience as we paddled through narrow channels, spotting crabs, fish and herons, and admiring the surrounding forest as the sun glanced off the water.
