In Costa Rica's less-visited Cano Negro district, explore vital wetlands and a slice of the country that's reminiscent of Costa Rica before its boom in popularity. The Rio Frio meanders through this internationally recognized ecosystem, creating a labyrinth of marsh, forest and riverine habitats that supports more than 300 bird species and abundant mammals, including three-toed sloths, monkeys and elusive jaguars. Search for wildlife from the bow of our exploratory boat as we delve into this secluded roadless area. We’ll also hike through the dense jungle of Tenorio Volcano National Park, where the Rio Celeste’s mineral-rich turquoise waters flow into a waterfall, cascading nearly 100 feet into a vibrant pool. Learn about the culture and cuisine of the Maleku people, Costa Rica’s smallest remaining Indigenous tribe, and explore the cloud forest from on high via secure suspension bridges. An in-depth immersion to one of the planet’s most important wetlands, this trip reveals Costa Rica in its most natural state.
