About a quarter of the land is under forest, and under government protection. This is a nature lover’s paradise. The steamy rain and cloud forests are filled with colourful birds such as macaws, and animals as diverse as sloths, anteaters, spider monkeys and howler monkeys. Visitors can get up close to these animals by hiking on the canopy walks that crisscross the forest treetops then they can zipline down and hike amongst the trees.
Here volcanoes punch holes in the forest canopy. The Arenal Volcano is one of the most active volcanoes in the world, and warm thermal waters flow through the rivers around her.
