Costa Rica is a small country with an outsized number of waterfalls. The combination of volcanic mountains, year-round rainfall, and dense rainforest creates conditions where water falls from almost every ridge. What makes Costa Rican waterfalls different from waterfalls in drier countries is what surrounds them: the jungle closes in on all sides, toucans call overhead, and the pools at the base are warm enough to swim in for most of the year.
La Fortuna Waterfall
”
La Fortuna Waterfall near Arenal is the most visited in the country — and with good reason. The 70-metre cascade drops into a pool of impossible turquoise against a wall of green jungle. Getting there requires descending 500 steps to the base and climbing them back up, but the pool is swimmable and the setting is exceptional. The waterfall is privately managed and charges a small entrance fee; arriving before 9am means having the pool almost to yourself before tour groups arrive from La Fortuna town.
Nauyaca Waterfalls
”
The Nauyaca Waterfalls in the Dominical area require a 15-kilometre round hike or a horseback trip through farmland and jungle to reach. The reward is a two-tiered waterfall feeding the best swimming hole in Costa Rica — a deep, wide pool under the upper falls, shaded by the cliff and the forest above. Because of the distance, it rarely feels crowded even in high season. The lower falls are accessible within 30 minutes of the upper pool and offer a completely different character: wider, shallower, set in open river rocks.
Río Celeste Waterfall
”
Río Celeste runs through Tenorio Volcano National Park and is one of the most surreal-looking rivers in the world: a vivid sky-blue colour created by a chemical reaction where two clear streams meet and scatter light. The waterfall at the top of the trail is smaller than La Fortuna but the colour of the water in the pool below is unlike anything else in Central America. The 9-kilometre trail through primary rainforest passes the teñidero — the exact spot where the rivers merge and turn blue — and a series of hot springs and bubbling mud pools along the way.
Best Time to Visit
”
Costa Rica’s waterfalls are most powerful during and just after the rainy season, from May through November. The dry season from December to April produces lower water volumes but clearer trails and easier access. The waterfalls in the south Pacific (Nauyaca, Uvita area) and the Caribbean coast run year-round. La Fortuna and Tenorio are accessible in any season but the trails get muddy during heavy rain.
