Rio Claro Nature Reserve (Reserva Natural Cañon de Río Claro) is one of the biggest highlights during my time living so far in Medellín. It is considered by many as one of the must-do activities in Antioquia. And it is located only about three hours from Medellín.
Rio Claro is also the perfect place to enjoy an abundance of nature with a picturesque crystal-clear river, canyon and tropical rainforest. In addition, it enables completely unplugging from the hectic pace of daily life in the city.
I have traveled to 46 countries and have been to some of the most geographically stunning places – including the Galápagos Islands, Salar de Uyuni and Himalayas – over the past three decades.
Still, for me, few places in the world can compete with the Rio Claro Nature Reserve in southern Antioquia, or more specifically, the Middle-Magdalena region. Note the above photo of Rio Claro is by Motero Colombia.
History of Rio Claro
Established in 1970, the 1,606 acre (650 hectare) Rio Claro Nature Reserve is a private reserve and it’s a spectacular example of Colombia’s biodiversity. It is located about 94 miles (152 km) southeast of Medellín on the Medellín – Bogotá highway.
The reserve sits atop the remnants of a shallow sea and coral reefs. It is literally a marble canyon with a river running through it. And the sieve-like topography provides striking artistic evidence of 6 million years of hydropower. The karst formations include deep caves, stalactites, stalagmites, rock ripples and ladders.
The formation of Rio Claro’s watershed, has its origins in sedimentary deposits from the Devonian Period (419-358 million years ago). The Rio Claro area formed part of a large shallow-sea that received sediments deposited by the Amazon River. At the time the Amazon flowed from south to north, originating in Brazil and forming a large delta in present-day Colombia.
As the Central Andean mountain range emerged in Colombia, the limestone sediments that were deposited during the Devonian Period were transformed into marble crystals that were gradually exposed and sculpted by Rio Claro’s waters. This resulted in the canyon that we see today.
About 4 million years ago, the shallow sea began to subside, as the limestone deposits emerged. Finally, about 2 million years ago, waters withdrew permanently. And this coincided with the emergence of the Isthmus of Panama and the separation of the Pacific and Atlantic Oceans.
An Abundance of Nature and Biodiversity
Almost every area of the reserve offers a view of the river, canyon and tropical rainforest. This exquisite framing creates a Garden of Eden effect, further accentuated by the sublime chorus of birds, insects and monkeys.
Here, the diversity is not simply geological. Animal species within the reserve are estimated at 100 species of mammals, 350 species of birds, 70 species of reptiles, 45 species of amphibians, and 50 species of fish, beyond abundant species of insects and invertebrates.
But what is most easily seen? Monkeys, otters, toucans, iguanas, sloths and giant blue Morpho butterflies!
According to Álvaro Cogollo, Director of Medellín’s Botanical Garden,
“Rio Claro is one of 58 endemic hotspots in Colombia that has a multitude of species found nowhere else in the world.”
This includes all manner of plant life. This is a tropical rainforest set at 350 meters (Medellín is 1,500 meters) so it’s slightly humid and rich with trees, flowers and plants not seen at higher elevations.
Exploration of this vast landscape is a delight, its mysteries and lushness accessible and safe. Just be sure to bring a flashlight or headlight for evening walks, as none of the pathways in the reserve are illuminated.
Rio Claro Activities
Visitors to Rio Claro can partake in several activities appropriate for a range of abilities. There is a two-hour and thirty-minute Class I and II (out of a six-point scale) rafting trip in inflatable rafts. And this rafting trip provides access to bird, reptile and monkey sightings as well as a leisurely swimming break.
A three-hour Cueva de los Guacharos cave and stream walk is also offered, giving access to Oilbird sightings and the psychedelic formations within. This is a somewhat challenging activity as it includes wading through waist-high water. In addition, there is zip-lining, rock-climbing and naturalist walks.
The rafting activity costs 25,000 pesos per person. All other activities at Rio Claro cost 20,000 pesos per person. Make sure to make reservations for any activities at the reserve’s activities booth. Many of the activities take place in the morning. So, to participate you need to stay overnight.
Also, there are many swimming beaches throughout the reserve. Most have lifeguards and ropes set up to allow swimmers to safely cross from one side of the river to the other. Take care though, the river may seem calm on its surface, but it has strong, deep currents worthy of precaution.
My two favorite beaches were Playa de Marmól (Marble Beach) located directly in front of the El Refugio, with its massive slab of marble for sunbathing and Playa del Manantial.
Playa del Manantial has direct access to the Caverna de los Guácheros (Oilbird cave).
Relaxation sets in almost immediately, deepened by the cool, clear water and an impossibly blue sky.

Making reservations is mostly easily done by visiting Rio Claro’s office adjacent to Parque Poblado in Medellín. This ensures getting the room you want, clarifying details and instructions on how to deposit funds into Río Claro’s Bancolombia account.
- Hours: Monday to Friday 8:00 a.m. to 6:00 p.m.
- Phone: (574) 268 8855 – (311) 354 0119

Note that Rio Claro has a no refund policy but customers reportedly can reschedule reservations for a period of up to six months, if needed.
Rio Claro Recommendations
The best time to visit is not during the rainy season due to the river being pretty muddy. Other times of the year, Rio Claro lives up to its name in Spanish – “Clear River” with crystal-clear water. In addition, during the week is the best time to go as you may have the place nearly to yourself.
Also keep in mind that English is not widely spoken among staff. So, please be patient. Furthermore, no pets are permitted on the reserve for safety reasons. So, leave pets at home
Rio Claro does does not assume any responsibility for objects of value left in rooms or in common areas. The front desk will store any valuable (cameras, jewelry, cellphones, electronics and other items of value) in a safe, accessible at your request. Also the tap water at Rio Claro is not potable. So, drinking bottled water is recommended. Water in the reserve comes from natural springs, and is untreated.
Make sure you come prepared with sufficient Colombian cash. Only cash is accepted inside the reserve for payment. The reserve does not accept credit cards or checks. The nearest ATM machine is at the pueblo Doradal, which is about 30 minutes away. And reportedly this ATM doesn’t always work.
In addition, I recommend bringing a flashlight, towels, swimsuit, sunblock, mosquito repellant, hiking shoes and water shoes. Also, luggage without wheels is preferred, such as backpacks.
Location of Rio Claro Nature Reserve
How to Get to Rio Claro
Visiting Rio Claro is easy from Medellín. Simply take a TransOriente bus for 25,000 pesos from the Terminal del Norte. The buses depart about every 30 minutes.
The trip is approximately three hours (or about five hours if coming from Bogotá). However, landslides and holiday weekends can significantly slow travel time. The entrance to the reserve is located roughly one-third of the way between Medellín (94 miles – 152 km from the city) and Bogotá (164 miles or 264 km from Bogotá).
Make sure to tell the bus driver you want to be dropped at the entrance to Rio Claro by saying you want to be dropped off at the “entrada de la reserva Rio Claro.” This will ensure the driver will stop directly in front of the entrance to Rio Claro reserve.
To return to Medellín just flag down any bus on the side of the highway which pass every 30 minutes or so.

The Bottom Line – Rio Claro
Give yourself at least two nights at Rio Claro. I highly recommend staying at El Refugio, specifically the third-floor corner rooms. Although they are the most expensive, the jaw-dropping views from the comfort of a queen size bed draped in a mosquito net are unforgettable.
Rio Claro is truly the quintessential place to unplug. There are no TVs here and Wifi is only available at the main entrance reception area. So, let the jungle sounds lull you to peaceful sleep and discover the extraordinary beauty of nature.
