Key facts at a glance

Río Celeste and Tenorio Volcano National Park

Río Celeste is famous for its astonishing sky-blue water. The river flows through Tenorio Volcano National Park, between Guanacaste and Alajuela. Its color comes from a natural optical effect when two clear rivers meet at Los Teñideros: minerals in the water form particles that scatter sunlight, turning the water blue.

Swimming is not allowed in the park

Swimming is prohibited inside Tenorio Volcano National Park to protect the river and visitors. Some private properties outside the park offer river access where swimming may be allowed; check locally.

The main trail

The main trail is roughly six to seven kilometers round trip and includes the Río Celeste waterfall (reached via a long staircase), a lookout, the blue lagoon, borbollones (bubbling waters) and Los Teñideros. It can be muddy, especially in the rainy season. Allow three to four hours.

Tickets and hours

Buy tickets online in advance through SINAC. The park has daily entry times and capacity limits, and the last entry is usually early afternoon.

Getting there

The park is about 1.5 to 2 hours from Liberia or La Fortuna, via Bijagua or Guatuso. Roads are paved but may have rough stretches.

Best time to visit

The water's color is often brightest on sunny days in the dry season. After heavy rains, the river may look cloudy rather than blue.

What to bring

Waterproof hiking shoes, rain gear, water, snacks, insect repellent and a camera.

Common mistakes

Expecting to swim in the park, arriving late, and visiting right after heavy rain are common mistakes.

Why the river is blue

The blue color forms at Los Teñideros, where two clear rivers, Río Buenavista and Quebrada Agria, meet. Researchers have explained that minerals from the volcanic rivers combine to form larger particles, called aluminosilicates, that scatter sunlight and make the water look turquoise. The color isn't a dye; it's an optical effect, which is why it varies with light and rain.

Trail highlights

The Río Celeste waterfall is the most photographed spot, reached via a steep staircase of several hundred steps. The Mirador offers views of the Tenorio Volcano when skies are clear. The Laguna Azul is a calm blue pool. At Los Borbollones, bubbles from volcanic gases rise through the water. Los Teñideros is the turning point, where you see the two rivers meet and change color.

Where to stay

Bijagua has lodges near the park, with wildlife, tapir tours and night walks. Some lodges near the park entrance have hot springs or river access outside the park where swimming may be allowed.

Combining with other destinations

Combine with La Fortuna and Arenal, Rincón de la Vieja, or Liberia and the Guanacaste beaches.

Weather tips

Tenorio is a rainy area, even in the dry season. Expect mud, and bring rain gear. Mornings are often clearer.

Respect the park

Stay on trails, don't swim or touch the water, and take trash with you.

Sample day

Leave La Fortuna or Liberia early, arrive at opening, hike the trail to the waterfall and Los Teñideros, have lunch at a soda in Bijagua, and visit a private river spot or hot spring outside the park in the afternoon.

Guided or self-guided?

The main trail is well marked and easy to hike independently. A guide adds wildlife spotting and explanations of the river's color and volcanic features, and tours usually include transport from La Fortuna or Guanacaste.

Trail difficulty

The trail is moderate, with mud, roots, stairs and some steep sections. Most reasonably fit hikers, including older kids, can complete it. Rubber boots are often available to rent near the entrance in rainy months.

Swimming alternatives nearby

If you want to swim in blue-tinted water, ask locally about private properties downstream of the park that offer river access, sometimes with hot springs. Rules, fees and conditions vary, so confirm with your lodge. Inside the park, enjoy the views and photos only.

Wildlife on the trail

Watch for monkeys, coatis, toucans, frogs and colorful butterflies along the trail. The area around Bijagua is also known for tapirs, seen mostly on guided night tours at private reserves.

Final tip

Check the weather the day before, arrive at opening, wear waterproof shoes and plan the rest of the day around what you see.

Río Celeste rewards patience: on a sunny morning, the color is unforgettable.
