Caño Cristales

Within the Sierra de La Macarena National Natural Park in Colombia, this exquisite river is aptly nicknamed the River of Five Colours. Caño Cristales is considered one of the most beautiful waterways in the world and for several months each year, it dazzles with interchanging hues of pink, green, yellow, blue and black. This natural display occurs thanks to an endemic aquatic plant that changes colour when exposed to sunlight.

The Caño Cristales is a famous river located in la macarena/meta for the multiple colors it has produced by specific algae of name Macarena Clavijera. I travel in motorcycle from Bogota to la macarena for the way that lead to vista hermosa to caño cristales. The way is full of mud during winter but all the people of the hamlets is very helpful and attentive to help travelers because this way is extreme. During the trip I cross Vista hermosa, pinalito, santo domingo, el chorizo, el alto del avión, caño yarumales, caño indio to finish in caño cristales and never paid for enter there and totally recommend to know this place

The 62.1-mile-long river is in Colombia’s Serranía de la Macarena national park, in the province of Meta, and is known as the “River of Five Colors.” This “liquid rainbow” – as it is also called – is one of the South American country’s most spectacular natural wonders, thanks to its vivid colors. The bed of the river sports bright red, yellow, green, blue and black for the few months that conditions are right. Although the colors can be viewed from as early as mid-May and sometimes into December, they are brightest during June and November. **The colors are produced during the reproductive process of the aquatic plants in the river, which are called Macarenia clavigera, a species of the riverweed family Podostemaceae. During the wet season, the river runs fast and high, meaning the sun cannot hit the riverbed’s plants. During the dry season, there is not enough water to support the plants. The seasons rarely vary, so visitors wanting to catch sight of the spectacle have to head to the national park during those months that the bloom is most visible. The phenomenon happens nowhere else in the world. The area itself is a hotspot for biodiversity, where the Andes mountains and the Amazon and Orinoco basins converge – and is home to many endemic species. Caño Cristales is a Colombian river located in the Serranía de la Macarena, an isolated mountain range in the Meta Department. It is a tributary of the Guayabero River, itself a part of the Orinoco basin. Caño Cristales was found in 1969 by a group of cattle farmers.

Beautiful and nature

The river is commonly called the "River of Five Colors" or the "Liquid Rainbow," and is noted for its striking colors. The bed of the river from the end of July through November is variously colored yellow, green, blue, black, and especially red, the last caused by Rhyncholacis clavigera (syn.Caño Cristales (Spanish pronunciation: [ˈkaɲo kɾisˈtales]; English: "Crystal Channel") is a Colombian river located in the Serranía de la Macarena, an isolated mountain range in the Meta Department.

The river is commonly called the "River of Five Colors" or the "Liquid Rainbow," and is noted for its striking colors. The bed of the river from the end of July through November is variously colored yellow, green, blue, black, and especially red, the last caused by Rhyncholacis clavigera (syn. Macarenia clavigera) plants on the riverbed.[3] In recent years, the river has become a tourist destination; there were more than 16,000 visitors in 2016.The Serranía de la Macarena is located on the border of three large ecosystems, each of them with high diversity of flora and fauna: the Andes, the Llanos, and the Amazon rainforest. The representative biome of the Serrania de la Macarena is the hydrophytic rainforest: hot, warm, and cold. The tableland is home to about 420 species of birds, 10 species of amphibians, 43 species of reptiles, and eight primates. Caño Cristales is home to several species of fish (despite sometimes claimed to contain no fish), freshwater turtles and other aquatic animals. Caño Cristales river has a wide variety of aquatic plants. The water of the river is extremely clear due to the lack of nutrients and small particles. Almost unique is the bright red - pink coloration of riverbed after the rainy period from the end of June till November. This color is caused by great quantities of plant species Rhyncholacis clavígera (often known by its former name, Macarenia clavigera). This plant is only found in found in Caño Cristales and a few others rivers in the region, such as the Caño Siete Machos. These plants, which are green when young, then turn yellowish and finally various shade of red, adhere tightly to rocks in places where the river has faster current.The quartzite rocks of the Serrania de la Macarena tableland formed approximately 1.2 billion years ago. They are a western extension of the Guiana Shield. Caño Cristales is a fast-flowing river with many rapids and waterfalls. Small circular pits known as giant's kettles can be found in many parts of the riverbed, which have been formed by pebbles or chunks of harder rocks. Once one of these harder rock fragments falls into one of the cavities, it is rotated by the water current and begins to carve at the cavity wall, increasing the dimensions of the pit.

A beautiful place that you should visit if you are in Colombia, as one popularly says bacanería ❤️

🌊🌈The most beautiful rainbow river in the world Canyo Crystals River in Colombia This river is different from ordinary rivers and because of its various colors such as red, yellow, black and blue on the surface of the water, it is known as the Rainbow River and is located in the city of Meta in Colombia. #River #Colorbow #Colombia‌‌#beautiful#magnificent

Colorful aquatic plants and clear water combine to create a liquid rainbow. On the Serrania de la Macarena tableland in central Colombia runs a 60-mile- (100-km-) long river that for five months of the year turns a combination of red, green, yellow, and blue. The Caño Cristales’ colorful display is due to the blooming of an endemic plant called Macarenia clavigera, which requires a precise combination of water and sunlight levels to take on its bright red hues. Other green plants, the sandy riverbed, and the clear water reflecting the sky provide the other colors. Despite being rich in aquatic plants, the river is thought to contain no fish.
