Monteverde sits about 1,400 metres up - around the height of three Eiffel Towers stacked. It is so high and so wet that the trees grow plants on top of themselves: ferns, orchids, mosses and bromeliads cover every branch.
Walking through a cloud forest feels like walking inside a giant green sponge. The air is full of tiny water droplets. Drops drip off every leaf. You hear birds calling that you cannot see, because they are hidden in the mist.
The forest is full of bridges. High up in the canopy, dozens of metres above the ground, narrow rope-and-steel bridges let visitors walk treetop to treetop. Up there you might spot a hummingbird flying right by your ear, or a sloth slowly stretching for a leaf.
Cloud forests are rare. They cover less than 1% of the world's land. Monteverde alone has over 2,500 species of plants, 100 mammals, 400 birds and around 1,200 species of moths and butterflies. Many of them live nowhere else on Earth.
