Are you intrigued by the stunning blue waters of Celeste River and want to know more about this natural wonder? Maybe you’ve heard about its magical color and unique features but can’t find the exact details about why it’s so extraordinary. If you’re curious about it, you’re in the right place.

As experts in Costa Rica travel, we’ve got all the details you need to know! Here are 10 interesting facts about Celeste River, Costa Rica, that will make you want to visit this stunning blue river!

1. It Has the Most Magical and Enchanted Blue Waters in Costa Rica

Rio Celeste is formed by the confluence of two rivers: the Buena Vista and the Quebrada Agria. The scientific explanation behind Rio Celeste’s vibrant blue color involves a very curious phenomenon resulting from a chemical reaction between the volcanic minerals in these rivers.

The river’s blue color occurs because the acidic waters of Quebrada Agria mix with the alkaline waters of the Buena Vista River. This combination creates tiny particles that scatter sunlight, making the water appear a striking blue.

This area, where you can witness the river changing color, is called “Los Teñideros” or “The Dyers” in English. It is precisely where the two rivers merge, and the chemical reaction begins.

2. It Is Home to a Variety of Species

The area around Rio Celeste is a rich habitat for wildlife. This region includes primary and secondary rainforest, with the dormant Tenorio Volcano covered by dense cloud forest.

As you explore, you’ll encounter howler, white-faced, and spider monkeys swinging through the trees and sloths lounging in the canopy.

Also, you might spot tapirs, anteaters, collared peccaries, coatis, and various wild cat species. Birdwatchers will love the area too, with exotic birds like bell birds, motmots, toucans, parrots, hummingbirds, and woodpeckers!

3. It Is Surrounded by the Verdant Tenorio Volcano National Park

Visiting Rio Celeste involves hiking through the lush Tenorio National Park. Located in the Guanacaste Volcanic Mountain Range, Tenorio Volcano’s four cones provide stunning scenic overlooks of the surrounding areas.

If you’d like to visit the park, you’ll need to know:

• Park hours are 8 a.m. to 2 p.m., and visitors are allowed to stay until 4 p.m.
• Park entrance fees are $12 USD for adults and $5 USD for children (ages 2-12), payable by credit or debit card only.
• Since August 1, 2023, tickets must be purchased online in advance on the SINAC website, as they are no longer sold at the entrance.
• Parking costs approximately 2000 colones (around $3.78) per car, payable only in cash.

4. It Has a Stunning Waterfall

Rio Celeste has a stunning waterfall that offers breathtaking views, plunging 98 feet into a pool of bright blue water surrounded by dense tropical forests. To reach this natural wonder, you need to hike 3.5 miles (5.6 kilometers) from Tenorio National Park’s ranger station. This trail takes about an hour each way. 

5. It Has Natural Hot Springs

As you explore the main hiking trail in Tenorio Volcano National Park, you’ll also pass through an area known as Los Hervideros, or Borbollones.

Here, you’ll see a natural phenomenon that looks like bubbling hot springs. Water bubbles up because volcanic gases are escaping from the earth’s crust. These gases cause small bubbles in the water, making it look like it’s boiling.

Unlike other hot springs in Costa Rica where you can relax, Rio Celeste hot springs are completely forbidden for bathing, with temperatures reaching 94 degrees. So, while you can’t get into the water, it’s still a stunning sight to witness.

6. It Has a Legendary and Biblical Origin

A fun and enchanting legend about Rio Celeste says that when God finished painting the sky, he cleaned his brushes in this river, creating the sky-blue river.

While this is only a legend, the story adds a magical and mythical element to the already stunning natural beauty of Rio Celeste, making it feel like a divine masterpiece in the heart of Costa Rica.

7. There Are On-Going Conservation Efforts to Protect Its Biodiversity

To preserve the stunning beauty and biodiversity of Rio Celeste for future generations, several conservation efforts are in place. These include:

• The number of visitors is restricted to prevent overcrowding.
• Single-use plastic items are banned to keep the water clear and unpolluted.
• Nearby farming and development activities are monitored to minimize their impact on the environment.
• Pets are not allowed in the park to protect wildlife and maintain the natural habitat.
• Swimming in the river is prohibited to preserve its unique blue color and ecological health.
• Drones are not allowed to prevent wildlife disturbances and ensure a peaceful experience for visitors.
• Alcohol and smoking are prohibited to keep the park serene and clean.

8. It Has Adventurous Hiking Trails

Rio Celeste offers a 3.5-mile (5.6-kilometer) hiking trail starting from Tenorio National Park’s ranger station. The hike to Rio Celeste takes about an hour each way.

The first 20 minutes of the trail are flat and paved, making it accessible for hikers of all ages and skill levels.

As you approach the Rio Celeste waterfall, the trail becomes unpaved, and you’ll need to navigate 250 steep stairs down to the waterfall.

While the return ascent can be challenging, the stunning view of the powerful waterfall cascading into its vibrant blue pool makes the hike worth the effort.

9. It Has Unique Natural Pools

Something truly fascinating about Rio Celeste, Costa Rica, is that in some parts of the river, the water flows more slowly, forming peaceful lakes or lagoons. This area is known as the Blue Lagoon or Laguna Azul. Here, the bright blue water becomes even more intense, especially on sunny days.

10. It Is an Indigenous Heritage

Rio Celeste has connections to Indigenous heritage, particularly through the nearby Maleku Indigenous Reserve. The Maleku people, an indigenous group of Northern Costa Rica, live around Rio Celeste and Tenorio Volcano National Park.

The Maleku community preserves its unique language, customs, and traditions, which contribute to the region’s cultural richness.
