>  Blog   >  6 Things You Need to Know Before Visiting Rio Celeste

It’s hard to believe I lived in Costa Rica for a year and a half. Well, that’s not entirely true. Some days it felt as if I’ was there for an eternity and never had any life other than the one was currently living. Some days it felt as if the magic of living above the streets of Madrid, traveling to such wondrous sights as the Fjords of Norway, lights of Paris and tulip fields of Holland never happened and was all just a dream. But I digress.


As my time in the land of pura vida rapidly approached an end, I tried to squeeze in a few last-minute trips. I jumped off a 50-foot waterfall in Montezuma and rode an ATV along the beaches of Santa Teresa. And I ventured to Costa Rica’s northern region of Alajuela to take in the otherworldly blue of Rio Celeste. I traveled with my favorite Tico travel buddy, Diego, which gave me great local insight (as well as a handy photographer). In today’s post I’ll not only share with you stunning photos that will make you


want to start your trip right now, but also what you need to know before visiting.

6 Things You Need to Know Before Visiting Rio Celeste

1. The Journey to Rio Celeste is a Trek

things to know before visiting rio celeste the journey is long

Rio Celeste, undoubtedly Costa Rica’s most enchanting river, is a 14-kilometer stretch of magical blue located in Tenorio Volcano National Park which is in the Northern lowlands. Unless you have a private plane, the journey to Rio Celeste is quite a trek no matter how close it may appear on a map (Don’t worry — it’s a long journey but well worth it in the end!)

Getting to Rio Celeste via public transportation would be a miserable, arduous journey requiring a full day of travel time, several bus changes and long stretches of walking or taking a taxi. To this end, you really need a car to visit Rio Celeste and one that is four-wheel drive.

A word of warning about renting a car in Costa Rica. DO NOT- I Repeat, do not – rent a car with Payless Car Rental. Diego and I made a reservation for a car at a very low rate online and called to confirm. However, when we showed up to their location on Paseo Colon they claimed to have no record of the reservation and blamed their error on me being a gringa and making the reservation from the United States even though I made the reservation from Costa Rica with a Tico watching me (and then called the office to confirm). Without a word of apology we were turned out onto the street. Diego and I desperately ran down the avenue, which is home to several car rental companies, in search of a last-minute rental. Four stops later, we were able to rent a car from Budget. Long story short, just book with Budget in the first place.

If you are traveling from San Jose the drive is about four hours, but can be up to six if you hit San Jose traffic at the wrong time and it takes you two hours to leave the city. If you are traveling from Liberia the drive is about two hours. Most of the roads you’ll take are paved but the last eight kilometers or so to the park entrance are unpaved and rocky.

2. Choose Accommodations Nearby

You could make Rio Celeste a day trip from Liberia or La Fortuna, but to maximize the experience I recommend staying nearby. There’s a few hotels that are not far from the park’s entrance. I stayed at Rio Celeste Hideaway Hotel and would definitely recommend this property to other travelers. It has a pool with a swim up bar and hot tubs that make for the perfect relaxing activity following a long drive or day of hiking.

2.The Hike to Rio Celeste is Long and Muddy

Once you reach the entrance of Tenorio Volcano National Park you aren’t at Rio Celeste quite yet- a long and muddy hike awaits you.

The first 20 minutes of the trail are not muddy and an easy walk on a flat surface. Once you pass the turn off for the waterfall the trail starts to descend and becomes muddy. And by muddy I mean you will spend 30 minutes lifting your feet up and out of thick mud.

For an additional fee you can rent boots at the park entrance office (something only gringos do). If you are wearing water proof hiking boots you’ll be fine and can just wash them off at the fountain at the end of the hike.

3. Hike to the Furthest Point First

Diego and I received a great piece of advice from a local before the hike that we greatly appreciated first — save the waterfall for the end and hike to the furthest point first.

Roughly 45 minutes down the trail is a mirador, or panoramic vista. Don’t let this name fool you — the first place you can actually see the stunning blue waters of Rio Celeste is about 15-minutes further down the trail at Laguna Azul, which resembles the magical mermaid lagoon from Peter Pan.

Continue down the trail, which parallels the river to the Borbollones, a portion of the river that bubbles do to sulfur.

Continue down the trail and cross a rickety, wooden bridge that feels like it belongs in Indiana Jones.

Further down is perhaps the most distinguishing portion of the trail and several low bridges lead across the jewel-tones of the river. You’ll definitely want to take photos here and spend some time soaking in the beauty around you.

The trail continues to parallel the river before reaching los Teñideros. Rio Celeste is formed by two rivers that mix together. At this final stop along the trail you can see the two rivers merging to form the brilliant blue.

Then turn around and hike back to the waterfall the sight of which will re-energize you after such a long hike.

4. Why is Rio Celeste So Blue?
things to know before visiting rio celeste- why is rio celeste so blue

After hiking for so long next to this magical river, chances are you’ll find yourself pondering the question – why is Rio Celeste so blue? 

Rio Celeste means light blue river. Legend has it that after God was done painting the sky he washed his brushes in the river and it now bears this color.

A team of researchers from the Universidad de Costa Rica and the Universidad Nacional came to a different conclusion. Rio Celeste is formed by the converging of two clear water rivers, Quebrada Agria (Sour Creek) and Rio Buena Vista (Good View River). The point at which these rivers mix is called el Teñidero.

The researchers found that the blue color is not a chemical phenomenon, but an optical one. The blue color is seen by the human eye in the waters of the river. Once the water is removed from the river bed it becomes clear. A type of mineral composed of aluminum, silicon and oxygen, while suspended in the water, reflects light from the sun, making the water look blue. The combination of the traces of this mineral in both rivers is what causes the color from el Teñidero onwards. 

5.  A Word About Rio Celeste Waterfall

The most famous, if not the most stunning, feature in the national park is the Rio Celeste waterfall. The base of the waterfall is accessed by descending 250 steep steps. Again, I recommend saving this stop on the trail for last as it is a great reward for having almost completed the difficult hike. The waterfall is fenced off and no swimming is allowed in the national park, but the view here is so savory, hopefully you won’t mind!

6. Where to Swim in Rio Celeste

things to know before visiting rio celeste- swim in rio celeste

Swimming in Tenorio Volcano National Park is prohibited. However, the blue waters of Rio Celeste continue for 14-kilometers, so that means there are sections just as stunning located out of the park. If you drive along the river, you may notice some locals, or ticos, taking a dip in local swimming holes. Warning: the river does have high levels of Copper Sulfate which are known to irritate skin, but this doesn’t stop ticos (or me) from swimming.

We found a spot that was full of a lot of swimmers on the road from Katira heading toward Guatuso. It’s on your right hand side next to a restaurant and lodge. Parking is available.

    Hi! Thanks for the valuable information! Is the hike free since it’s a national park? I found on one website that there are two routes, and one is shorter. Is this true?

    We are planning a trip to Costa Rica at the end of September and have read that the Caribbean coast will have the best weather at that time of year… we really wanted to see this river though, will it be pretty impossible to do so then?

    Hi Everyone! I am from Paraguay. This was my first place that I visited since I arrived in Costa Rica! It was a long way from the capital; however, it was totally worth it! My recommendation is that you should go during a day that there is no raining. This is important to know because the water will not be completely “celeste.” Also, wear some boots and bring a jacket in case you need it!

    I guess the times have changed. I visted Costa Rica many years ago and was lucky enough to swim by the waterfall. The hotel resort tour guide encouraged it. It was the most amazing day of my life. Hearing now that it is prohibited saddens me. You guys can email me at for photos.

    Thank you so much for all of your details. I am looking forward to going to explore Costa Rica for about 8 days. I am planning to go to Playa Conchal, Rio Celeste and I also wanted to visit a volcano. What is the closest volcano near that area. I want to get the best expoerence. Any recommendations? I’m flying straight to Liberia and leaving from San Jose. Do you have ideas of which location I should travel to first and last to end up closer to San Jose airport? And I will defiantly be renting a SUV! Should I be ok with a gps to get to each location? Any other recommendations of hotels please send my way. Thanks again!

    I went to Costa Rica 4 weeks after I broke my foot so was still in walking boot. I am 64 but was happily able to trudge a well placed foot at a time up to the falls. The path thru the jungle is beautiful and we saw a couple of snakes, toucans, butterflies & birds & a tapir print in the mud. I used a walking stick & a friends arm to steady but it’s an amazing few hours of sights. Of course the next day I was pretty sore! But so glad I was there in dry season, Jan 4th so I was able to do this hike partially disabled. The greenery is amazing with the bright blue falls!

    I see everywhere they offer tours busses and trips etc .. did you find going here or other places in Costa Rica would you just rent a car and venture out to various places or go with trusted tours? Do you have to pay for parking etc… when you go to various national parks?

    Hello. Thank you so much for sharing. I will be going to rio celeste in 1.5 weeks from now, and have been avidly warned that a serious SUV is needed to get to where we are staying, which is pasado rio celeste.
    Any feedback?

    Hey Laure,

    This is awesome and I am planning to follow your tips! I am curious how long your hike took in total and is it possible to do it on a Sunday? I wasnt sure if the park closed? Also any recommendations for viewing wildlife nearby?

    Hi. How long does it take from Arenal to Rio Celeste? Tours from Arenal are very expensive. 100 per person. Would you recommend renting a car or staying near rio celeste? Are there other things to do near?

    This is really helpful.

    Do we need a guide, or is the trail easy to follow? How many hours did it take you?

    Also, do you remember how much was the entrance to the park?

    The trails in the Rio Celeste (Volcan Tenorio) National Park have been repaired so they don’t get muddied when it rains and thus the hike is much easier. Also, the path down to the waterfall has been made completely accessible,including proper steps and handrail throughout. It tends to get busier on weekends so it’s preferable to visit the park during the week. Finally, all roads aroun the area have been paved and there is public bus service direct to the area. Car travel is much better in CR due to limited public transportation.
