Caño Cristales is a famous river in Colombia known as the “river of five colors”, which is also considered by many to be “the most beautiful river in the world”. The river has also been called the “liquid rainbow”.

During several months each year, Caño Cristales becomes a rainbow of vibrant colors including red, green, yellow, blue and black hues in a natural display that reportedly happens nowhere else on Earth.

Several readers on the Medellín Guru website asked about Caño Cristales and when is the best time to go. So, I wrote this up-to-date guide to Caño Cristales with plenty of time to plan for the next season that starts in June this year.

Serranía de la Macarena National Park

Caño Cristales is located in the Serrania de la Macarena National Park, which is located in the Meta department of Colombia. In addition, Caño Cristales is a tributary of the Guayabero River.

Serranía de la Macarena is a protected national park in Colombia that covers 2,500 square miles (6,200 square kilometers). The Serranía de la Macarena park is located where three large ecosystems in Colombia meet, each of them with a high diversity of flora and fauna: the Amazon rainforest, the Andes mountain range and the savannah plains of the East Llanos.

Serranía de La Macarena is considered one of the most biodiverse areas of Colombia. It reportedly is home to over 500 species of birds, 100 species of reptiles, over 2,000 species of plants and over 1,200 species of insects.

Until the mid-2000s, nearby guerrilla activity rendered this part of Colombia almost completely inaccessible, as it was considered an area that was too dangerous. But the military took back control of the area several years ago and it’s now generally considered safe. And it has become a growing ecotourism destination.

Caño Cristales

For about six months of the year, Caño Cristales looks like any other river. But from about June to early December the river comes alive with red, green, yellow, blue and black hues.

Some people incorrectly believe that the river’s main colors come from algae or moss. However, the main reason for the colors is an endemic aquatic plant called macarenia clavigera. Most notably, this plant requires precise conditions, including the right water level and just the right amount of sunlight, to take on its bright hues.

In addition, Caño Cristales is a river with a relatively fast current along many parts with many rapids, waterfalls and several circular pits or holes.

Normally from mid-December to May, the river is closed to tourists to give the area’s ecology a break. Also, during the dry season there is not enough water to support the dazzling array of life in the river.

The season for Caño Cristales normally runs from the beginning of June to the end of November. And some years, it’s also open in early December. But it can sometimes close at other times. For example, last year, it was closed in late August for a while due to a lack of rain.

Location of Caño Cristales

How to Get to Caño Cristales

The closest town to Caño Cristales is La Macarena, Colombia. And there is no lodging or camping available at Caño Cristales. So, you will need to stay in La Macarena.

La Macarena is a frontier town that has a noticeable military presence. And La Macarena is a relatively small town with a population of about 30,000.

It is possible to get to La Macarena by land from Neiva. But this is a long trip of about 12 hours. And 4×4 vehicles are required due to some dirt roads. So, this isn’t recommended.

It’s also possible to get to La Macarena from San José del Guaviare via the Guayabero river. But this reportedly runs only one day a week and it’s a long trip at about eight hours. So, this also isn’t recommended.

The best way to get to La Macarena is by air. And there are seasonal flights from Bogotá (1 hour) typically on Monday, Thursday and Saturday; Medellín’s Olaya Herrea Airport (1 hour and 45 minutes) typically on Monday and Friday and Villavicencio (50 minutes) normally daily. Some flights are chartered by tour companies.

Furthermore, to enter the national park where Cano Cristales is located, you must be accompanied by a guide from a tour company. Also, reportedly a maximum of 200 visitors are allowed per day.

To get to Caño Cristales from La Macarena with your tour guide is normally a combination of boat, 4×4 and walking.

Caño Cristales Tour Companies

I recommend getting a package deal from one of the tour companies when traveling to Caño Cristales. This is what I did several years ago. The packages tours normally include guided tours, lodging, airfare and most meals.

Two tour agencies I recommend are Caño Cristales and Ecoturismo Macarena. Both agencies have many plans. Some plans include airfare and some plans don’t.

And it has a four-day plan with airfare from Medellín with three nights that costs 2,199,000 pesos. Caño Cristales has several more plans listed on its website with airfare from Bogotá, Medellín or Villavicencio.

Ecoturismo has a package that doesn’t include airfare for 590,000 pesos for two days and includes one night’s lodging and most meals. The same two-day plan with airfare costs 1,181,000 pesos from Villavicencio.

Ecoturismo has several more plans of different day lengths listed on its website from Villavicencio, Bogotá, Medellín and Cali.  For example, a four-day plan with airfare from Medellín with three nights costs 2,100,000 pesos.
