Tenorio Volcano National Park
Park National park protecting Tenorio Volcano and waterfalls
Home to Tenorio Volcano and the Rio Celeste waterfall, Tenorio Volcano National Park offers rainforest trails, hot springs and guided hikes; visitors arrive for the turquoise river and cloudforest landscapes.
Tenorio Volcano National Park in Costa Rica protects the Tenorio Volcano and surrounding highland rainforest in the Guanacaste region, and is best known for the Rio Celeste phenomenon. The park conserves cloud forest, primary rainforest and volcanic terrain in a compact protected area.
The standout attraction is the Rio Celeste waterfall and the upstream confluence known as the Teñideros, where mineral chemistry and light scattering create a vivid turquoise-blue river that flows over a cascade into a natural pool. Trails lead visitors through dense forest to viewing platforms at the falls and along the river.
The park also encompasses the forested slopes and crater area of Tenorio Volcano, with hot springs and geothermal features present in lower valleys. The volcanic landscape and biodiversity make it a destination for wildlife viewing, birding and guided hikes.
Tenorio Volcano National Park sits in the northern highlands of Costa Rica’s Guanacaste Province, with the nearest small town commonly used as a gateway being Bijagua; access is by road from regional centers in Guanacaste and Alajuela provinces.
- Why the water is blue: The river's bright blue color occurs where two tributaries meet and suspended mineral particles scatter light; visual intensity varies with rainfall and river clarity.
- Trail conditions: Park trails can be muddy and slippery during the wet season; sturdy footwear and rain gear are recommended for hikes to the falls and the summit area.
What to See #
- Rio Celeste area: The Rio Celeste waterfall and its upstream 'Teñideros' where two clear streams meet producing the river's vivid blue color; the main fall features a dramatic cascade into a natural pool. The route to the falls follows well-maintained forest trails within the park.
- Volcanic highland and crater: The summit and crater area of Tenorio Volcano, which includes montane forest and viewpoints over the surrounding highlands; volcanic terrain supplies hot springs and geothermal features at lower elevations.
How to Get to Tenorio Volcano National Park #
From Liberia or the Nicoya Peninsula, drive toward the small town of Bijagua (signs for Tenorio/Río Celeste). From San José it’s about a 3-4 hour drive. Public buses run to Bijagua from larger towns, but arranging a shuttle or driving is more practical. Follow the signposted road into the park; the main trailhead is a short drive from town.
Tips for Visiting Tenorio Volcano National Park #
- Expect muddy trails - sturdy shoes and gaiters help on the steeper, rainforest sections.
- Hire a local guide for the Río Celeste loop (guides know the better viewpoints and wildlife spots).
- Arrive early (before 9:00am) to avoid tourist vans and to see Rio Celeste's color at its clearest without glare.
