Nevertheless, journey there from July to October, the reasonable months between the extremes of the moist and dry seasons, and also you’ll witness one in all Mom Nature’s crowning glories.
The 62.1-mile-long river is in Colombia’s Serranía de la Macarena nationwide park, within the province of Meta, and is named the “River of 5 Colours.”
This “liquid rainbow” — as additionally it is referred to as — is likely one of the South American nation’s most spectacular pure wonders, because of its vivid colours.
The mattress of the river sports activities shiny pink, yellow, inexperienced, blue and black for the few months that circumstances are proper. Though the colours could be seen from as early as mid-Could and generally into December, they’re brightest throughout June and November.
The colours are produced through the reproductive means of the aquatic crops within the river, that are referred to as Macarenia clavigera, a species of the riverweed household Podostemaceae.
Throughout the moist season, the river runs quick and excessive, which means the solar can’t hit the riverbed’s crops. Throughout the dry season, there may be not sufficient water to assist the crops. The seasons hardly ever differ, so guests desirous to catch sight of the spectacle have to go to the nationwide park throughout these months that the bloom is most seen.
The phenomenon occurs nowhere else on the earth. The world itself is a hotspot for biodiversity, the place the Andes mountains and the Amazon and Orinoco basins converge — and is residence to many endemic species.

Previous to the pandemic, 1000’s of vacationers flocked to see the spectacle yearly, which had raised issues amongst scientists that the river could also be threatened by overtourism.
Flavia Santoro, head of ProColombia, the nation’s tourism board, says that measures needed to be taken to guard the realm — so giant was the inflow of holiday makers. The company “severely restricted growth” of tourism infrastructure in La Macarena, the closest small city to the nationwide park, in addition to capping the variety of vacationers allowed in at 200 per day.
There have been so many vacationers visiting the area that despite the cap environmental authorities closed the vacation spot in December 2019 to guard the river. The closure was then prolonged as a result of pandemic.
For 18 months, till its reopening in June this yr, Caño Cristales didn’t obtain one single customer.
The impact, biologists say, has been been helpful for the area.
Faber Ramos, a park ranger and eco-tourism coordinator within the Colombian nationwide park system’s Orinoco area, says the pandemic has had a “optimistic impact” on the river’s well being and that there was now a better presence of fauna.
At its peak, round 15,000 vacationers had been visiting Caño Cristales per yr, and the tourism board was projecting the quantity to proceed rising.
Colombia had been experiencing a stable yearly development in vacationers visiting the nation, following the signing of the peace settlement with FARC guerrillas in 2016, which formally ended greater than 50 years of civil battle.
The signing noticed hundreds of thousands of worldwide vacationers flocking to discover the nation, in addition to Colombians themselves touring to areas that had beforehand been inaccessible as a result of battle — corresponding to Serranía de la Macarena nationwide park. Between 2017 and 2018 alone, the nation noticed customer numbers develop by 38%.
Balancing guests and the delicate surroundings

The expansion was vastly helpful for the tourism business and small cities that instantly discovered themselves catering to vacationers’ calls for for native guides, lodging and meals, however proved problematic for environments that had lain virtually untouched for half a century.
For many years, vacationers — even Colombian ones — stayed away from Caño Cristales because it was in a area managed by FARC guerrillas.
“The world is a hotspot of biodiversity,” says Carlos Lasso, senior researcher on the Humboldt Institute, a Colombian physique accountable for the nation’s biodiversity.
“It’s the place biologic parts of the Andes, Amazon and Orinoco basins converge. There are various endemic species and species of restricted distribution. The area of the Serranía de la Macarena has been a spot of battle for a few years…[but now] deforestation within the area is advancing at an alarming charge.”
Deforestation is one in all Colombia’s most urgent issues, with greater than 40 soccer fields price of timber logged day-after-day, and the realm of La Macarena is not any exception.
Deforestation impacts the patterns of rainfall, and the realm has seen much less rain, which means the water of Caño Cristales can flip from clear to a murky brown, which may finally kill off the Macarenia clavigera.
And because the nation reopens, the problem for Caño Cristales might be to not exceed the ecosystem’s capability for guests.
“It’s a troublesome space to guard,” Lasso mentioned, “as it’s so removed from any metropolis.”
“Though the federal government is doing properly, there may be all the time room for enchancment,” he mentioned, including that extra park officers had been wanted to guard and monitor the area.
New alternatives
The pandemic has supplied a possibility to reduce the variety of guests, and prioritize the realm’s well being.
Lasso is pragmatic; the river brings in a lot wanted cash to the area and locals have suffered an enormous lack of earnings.
The latest reopening of Caño Cristales additionally contains 10 new ecotourism trails, with strict working instances of seven a.m. to 4 p.m.
There are designated swimming areas within the river. Nevertheless, guests should not allowed to swim sporting solar lotion or bug spray, because the crops are delicate to the merchandise’ chemical substances.
The entry of single-use plastics, corresponding to baggage, bottles, straws, containers, plates and cutlery can be prohibited.
Not solely do vacationers journey to see the river, however the abundance of wildlife is a draw for the crowds. Turtles, iguanas and aguilas — Colombia’s nationwide fowl — are simply a few of the native species that may be noticed within the Serranía de la Macarena nationwide park, residence to greater than 400 fowl species.
Regardless of the challenges, Lasso is hopeful. “Extra younger Colombians are studying in regards to the surroundings, and tips on how to protect it.”
For those who go
Though the cap remains to be far decrease than it was pre-pandemic, the nationwide park is permitting a handful of holiday makers in day-after-day, so ensure that to guide excursions prematurely.
Most excursions vary from two to 4 days and can take you to different areas of the park, that are properly price seeing. The closest city to Caño Cristales is La Macarena. It’s not potential to camp throughout the park, so guests must “commute” from the city, which has primary lodging.
Be sure to deliver loads of money — ATMs within the city are restricted, and don’t all the time work. You’ll want your yellow fever vaccination, as often guests are requested to point out their certificates at La Macarena airport, and also you’ll additionally have to take anti-malaria tablets.
