Costa Rica's Cloud Forests: Where Biodiversity Reaches Its Peak

Costa Rica covers just 0.03 percent of the Earth's surface but contains nearly six percent of the world's biodiversity — a statistic that becomes entirely believable the moment you step into a cloud forest and hear the layered cacophony of birds, insects, and frogs that fills every cubic metre of air. The country's network of national parks and biological reserves protects 26 percent of its territory, one of the highest proportions of any nation on Earth, and the result is a landscape of extraordinary richness.

The Monteverde Cloud Forest Reserve, established in 1972 by a group of Quaker settlers from Alabama who had moved to Costa Rica to avoid the Korean War draft, protects 10,500 hectares of cloud forest straddling the Continental Divide at altitudes between 1,400 and 1,800 metres. The forest is perpetually bathed in mist blown in from both the Pacific and Caribbean slopes, creating conditions of near-constant humidity that support an extraordinary density of epiphytes — plants that grow on other plants — including over 500 species of orchid.

The resplendent quetzal, one of the most spectacular birds in the Americas, nests in the cloud forests of Monteverde and the nearby Santa Elena Reserve between January and July. The male's tail feathers can reach 60 centimetres in length, and its iridescent green and red plumage was sacred to the Maya and Aztec civilisations. Spotting one requires patience and an early start — the birds are most active in the hours after dawn — but a good local guide can dramatically improve your chances.

The canopy walkways at Monteverde — a series of suspension bridges strung between the forest giants at heights of up to 45 metres — offer a perspective on the cloud forest that is impossible from the ground. At canopy level, the forest is a different world: bromeliads and orchids crowd every branch, hummingbirds hover at flowers, and the mist drifts through the treetops in slow waves. The bridges sway gently underfoot, and the views through gaps in the canopy reveal the Pacific lowlands far below.

Beyond Monteverde, Costa Rica's biodiversity hotspots include the Osa Peninsula in the southwest, which the National Geographic Society has called the most biologically intense place on Earth. The Corcovado National Park on the peninsula protects the largest primary rainforest on the Pacific coast of Central America and is home to all four of Costa Rica's monkey species, two species of sloth, tapirs, peccaries, and one of the country's largest populations of scarlet macaws.

The Arenal Volcano, in the north of the country, is surrounded by a different ecosystem — lowland rainforest and wetlands that support caimans, river otters, and the Jesus Christ lizard, named for its ability to run across the surface of water on its hind legs. The hot springs fed by Arenal's geothermal activity have made the area a popular resort destination, but the wildlife around the lake and in the forests of the Arenal Volcano National Park is as rich as anywhere in the country.

Costa Rica pioneered the concept of ecotourism in the 1980s, and the country's tourism industry has been built around the principle that natural landscapes are worth more intact than developed. The result is a model that other countries have studied and attempted to replicate: a thriving economy built on the sustainable use of biodiversity, with local communities directly benefiting from conservation. Staying in locally owned lodges, hiring local guides, and visiting certified sustainable operations ensures that your visit contributes to the protection of the forests you have come to see.

Getting to Costa Rica: the main international airport is Juan Santamaría International Airport (SJO) near San José, with connections to North American and European cities. A second international airport at Liberia (LIR) in the northwest serves the Guanacaste beach region and is more convenient for visitors heading directly to the Pacific coast. Domestic flights connect San José to the Osa Peninsula and other remote areas; the roads to Monteverde and the Osa Peninsula are unpaved in sections and require a 4WD vehicle.

The Tortuguero National Park on the Caribbean coast is one of the most important sea turtle nesting sites in the Western Hemisphere. Green turtles nest on the beaches between July and October, and the guided night walks to observe nesting turtles are one of the most moving wildlife experiences in Costa Rica. The park is accessible only by boat or small plane, and the journey through the canal system that connects the Caribbean coast is itself a wildlife experience — caimans, river otters, and dozens of bird species are visible from the boats.

TravellingPros Tip: The Monteverde Cloud Forest Reserve and the adjacent Santa Elena Reserve are both worth visiting, but the Santa Elena Reserve is significantly less crowded and offers equally good wildlife watching. The entrance fee supports the local community school, and the guides are among the most knowledgeable in the region.
