Updated: Jul 7, 2022

Deep in the Sierra de la Macarena mountain range in the wilderness of Meta, Colombia lies a hidden place where magic still exists. Rare and bountiful wildlife populate an incredibly diverse ecosystem that, for a few months out of the year, gives rise to one of the most fascinating natural wonders on Earth – the Caño Cristales liquid rainbow. According to native legends, the Caño Cristales river escaped from paradise to wander among the mountains and prairies that make up this incredible region of South America. It has been called the rainbow river, the river of five colors, and a natural wonder of the world. Let us discover the magic of this remote and unique destination in Colombia together.


What's So Special

From December through May, this river is mostly ordinary, albeit composed of interesting rock formations and deep hidden pools. In June, it transforms into a shocking riot of vibrant colors – red, green, blue, yellow, and black. This incredible transmogrify remains through

late November and, although it may seem like magic, it actually takes place because of a combination of algae, mineral deposits, and the presence of the endemic plant species Macarenia clavígera. This flowering water plant is incredibly rare and unique, growing only in a few tropical climates of the world. Caño Cristales is the only place where it blooms so prolifically and spectacularly. Only recently reopened to public tourism, the river long remained a mythical and forbidden mystery, mostly unknown to the public before it became prohibited to go there in the 1980s. Now it is slowly becoming known as one of the natural wonders of the world as more and more visitors reveal stunning and breathtaking photos of the river in five colors.


What to See

Known as the Serranía de la Macarena, this mountain range and Colombian national park is so remote that you’ll need at least four or five days to travel there and fully enjoy its marvels. This area is one of the most biodiverse ecosystems on the planet.

Being made up of a strange amalgamation of large-scale grasslands, mountains, jungles, and waterways, an incredibly diverse multitude of animals and plants make their home here. The Serrania de la Macarena is home to jaguars, cougars, anteaters, eight different kinds of monkey, 550 species of birds, 1,200 species of insects, 100 species of reptiles, 50 different species of orchid flower, as well as an amazing array of plant life. When you’re not staring drop-jawed at the incredible Cano Cristales river, you can enjoy one of many different tours that are offered to explore this region and its range of flora and fauna.



Many have asked “Who discovered Caño Cristales?” Technically, the river has been known to indigenous locals for ages, but it was not discovered by modern society until 1969, when a group of Colombian cattle farmers stumbled across the river in full bloom. At the time, no airports were located anywhere near the region. Making the journey a long and hazardous trek through the wilderness that only the most adventurous travelers would dare to take.

The miraculous rainbow river remained a little-known gem hidden deep in the Colombian wilderness until guerilla groups commandeered the tiny village of Macarena, transforming it into a dangerous headquarters for militant activity and cocaine production.

Throughout the following years, the Colombian national army sought out the guerilla hideout and the battles that followed turned the entire area into a virtual war zone. Tourist activity in the Serranía de la Macarena was totally prohibited in the late 1980s for safety reasons and remained so until 2002, but since air travel was not widely available in the region until 2009, it did not become a popular tourist destination until recent years.


How to Get There

That is quite a challenging task. First get to Villavicencio from Bogota by plane or bus. From Villavicencio catch a plane to La Macarena. From here you can hire a guide, that would lead you to the river.


Things to Know Before you Get There

Due to the remoteness of the area and the host of regulations that surround Caño Cristales tourism, you’ll want to prepare beforehand:

  1. Get a yellow fever vaccination before you go. You will not be permitted to board the plane to Macarena without solid proof of a yellow fever vaccination.

  2. Book your tour guide and permit beforehand. Not only is a certified guide required by law, but also only 200 tourists are permitted to visit Caño Cristales per day, so you’ll need to arrange your tour accordingly. If you book through Palenque Tours, these details will be arranged for you.

  3. Don’t bother about sunscreen or bug spray. Once again, great care is taken to protect the Macarenia clavígera plants that lend the river its miraculous color. The delicate ecosystem does not hold up well against foreign chemicals and contaminants, so no sunscreen or bug spray is allowed within the park. Instead, opt for wide-brimmed hats, cool long-sleeve shirts, and water-resistant long pants, since the journey involves walking and canoe rides in the direct sunlight.

  4. Yes, you can take a dip in Caño Cristales and enjoy swimming. Although swimming is limited to designated areas, your guide will let you know when and where to swim.

  5. Pack a lot of drinking water. There will likely be no potable water available to purchase once you embark into the Serranía de la Macarena. Stay hydrated; it might get hot!

  6. Make sure you know when to go to Caño Cristales. The river only blooms between June and November. If you go during any other month, you’ll be sadly disappointed.
