Rio Claro, Colombia: A True Nature Reserve Near Medellin

A long swatch of limestone rock forms the riverbed along the Rio Claro which has carved deep ridges in the rockface.

Rio Claro, Colombia is a private nature reserve in Antioquia three hours southeast of Medellin.

It’s a popular way to escape the city and immerse yourself in nature. If you can avoid visiting during a holiday or weekend, it’s likely that you’ll nearly have the place to yourself.

Let’s explore this natural reserve and discover why it’s a true eco-lodge.

Rio Claro, which translates to “clear river,” flows through a marble canyon that has been shaped by the water over thousands of years. It provides a striking backdrop to base yourself in nature for a few days.

Its magnificence is further enhanced by the beauty of the surrounding tropical rainforest. The reserve is rich with wildlife, including tropical birds, monkeys, and the beautiful blue morpho butterfly.

Quick History of Reserva Rio Claro

In a world where “eco” has been overused and exploited for its popularity, Juan Guillermo Garcés has created the real deal. His passion for preservation is evident in his story of acquiring the land.

Growing up in Colombia during the last half of the 20th century, Garcés found himself visualizing the disappearance of the entire Middle Magdalena jungle within his lifetime. 

When a farmer told him a story of chasing a jaguar into the jungle only to discover a magical place with walls and floor made of marble, he set out with his brother to find the location.

After two days in the jungle, they discovered the transparent blue-green waters of Rio Claro and its surrounding natural beauty.

It was 1968 and the Medellin-Bogota highway was in the initial stages of being built. They knew it was only a matter of time before the forest would be destroyed. So, Garcés and his brother began to take possession of the land.

Many years passed, as Colombia experienced violent turbulence as a result of the drug trade. During this time, Garcés kept a low profile and only visited Rio Claro occasionally.

Then in 1997, Garcés was kidnapped. After a month in captivity, he managed to escape, all the while never giving up his dream of preserving the land. 

It wasn’t until 2005 that he began to build Reserva Rio Claro. Today, he has created an eco-sanctuary that continues to preserve the tropical rainforest by reinvesting profits into the conservation of adjacent land.

Things To Do in Rio Claro, Colombia

The Rio Claro Reserve feels a bit like summer camp. There are activities for nearly every adventure level.

As you enter Reserva Rio Claro, you are greeted with a map of the reserve. Then it’s a short walk on a shaded dirt road along the river to the restaurant and activity center.

A visit to Rio Claro does not require participation in any of the activities. If you’d rather do your own thing, continue along the path as you admire the river and reach other destinations, including Playa de Marmol, Templo del Tiempo, and Playa Manantial which sits across from Caverna de los Guacharos.

The most popular landmarks and activities are detailed below.

Playa de Marmol (Marble Beach)

A large flat piece of white marble juts into the river, creating the perfect area to sunbathe and an easy entrance to this swimming point along the river. Popular with families and groups.

Templo del Tiempo (Temple of Time)

This open cavern is a great example of how small mineral deposits form stalactites and stalagmites over millions of years. Located next to the trail, it’s much easier to access than the cave.

Thick stalactites hang from the ceiling of the curved, open-air cavern.

Playa Manantial (Spring Beach)

Long swaths of limestone rock make up the river bed here, where a natural spring flows into the river from Caverna de los Guacharos, The Cave of the Oilbirds.

From this point, you can continue the trail paths on your own towards Boca Caiman, or Alligator Mouth, where the river has carved a ledge that looks like the mouth of an alligator.

Explore Caverna de Los Guacharos

Adventurous travelers will want to go spelunking in this cave which is home to oilbirds. The small river that cuts through the cave has created beautiful marble rock formations.

A headlamp and flashlight are required, as well as a guide. Keep in mind, this is a moderately strenuous activity and you will likely get wet.

Cost: 35,000 Time: 3 hours Minimum Age: 12 years old

Where to Stay at Rio Claro

You absolutely should stay within the Rio Claro Reserve if you feel it’s within budget. The incredible experience of being within the nature reserve at night and in the mornings is worth it.

Honestly, once you factor in the included three meals per day, the 160-260,000 pesos rate per person seems quite reasonable.

However, I did find an inexpensive hotel in Doradal that was incredibly accommodating when we arrived on a bus in the middle of the night from Bucaramanga.

And if you have a tent, camping within Reserva Rio Claro is a budget way to stay within the reserve. Each option is detailed below.

Reserva Rio Claro Cabins

If you plan to stay overnight, I highly recommend staying in one of the cabins at the reserve. There are four options depending on your mobility, comfort level, and desire to be enveloped in nature. Each room is equipped with electricity, light, and a private bathroom. Rates, which include three meals per day, are quoted per person and can be found on the Reserva Rio Claro website.

El Refugio Cabins

Fully immersed in nature, these cabins are only accessible by foot via a 10-minute walk down the trail from the restaurant. There are four separate buildings, each with twelve rooms of double to quadruple occupancy. If you’re looking for the full experience, choose to stay here and get away from it all. It’s the only cabin with various rates depending on which room type you choose. The higher the price, the higher the floor and thus better views of the rainforest and its inhabitants.

Blue Morpho EcoLodge

Located on the two upper levels of the reserve’s main building, these rooms with forest views are ideal for those who do not wish to walk at night between the restaurant and their room. The rooms, which accommodate four to six people, were originally envisioned for school groups. It’s also accessible by car and steps away from the Adventure Activities center.

La Mulata Cabins

Surrounded by lush forest, these cabins are best for birdwatchers thanks to a large number of sightings from the rooms. Located between the main gate and the restaurant, these two buildings each contain four rooms with an occupancy of two to six people. Good for family groups and those that desire more comfort and accessibility since the buildings can be accessed directly by car.

Hotel Rio Claro

These independent bungalows are located along the highway and ideal for families and corporate groups that desire creature comforts rather than an immersion in nature. The rooms accommodate two to four people and some include air conditioner. The green grounds surrounding the hotel include a playground, restaurant, and pool.

Camping Rio Claro

If you have your own tent, you can choose to rent a campsite in Rio Claro overnight. This is definitely the budget option, but the campground is located close to the main entrance trail which means people will pass by as they enter and exit the park. You’ll also be on your own for food, whether you decide to make your own or purchase from the restaurant.

Camping rates are per person. 25,000 for one night; 35,000 for two nights; 45,000 for three nights.

Budget Hotel in Doradal

When I stepped off the bus in Doradal, the humidity smacked me in the face. It was two in the morning and the first thing I saw was a convenience store with colorful beach floats hanging outside the entrance. After flashbacks to my time on the Caribbean coast, I remembered we were in a small town in the Colombian rainforest.

We bought a snack at the store and walked a few meters to Hotel Conde, located along the highway strip. The hotel owner was waiting for us as promised even though our bus was two hours late! 

With only a few words exchanged, he gave us the key to the room which he had already temperature controlled by turning on the AC ahead of our arrival. I’m not one that requires or even chooses to use AC, but it was a big gesture in an area of the world that values minimal electric use.

Our stay at Hotel Conde in Doradal was fantastic. The (very) small and economical double room was at the back of the property, away from the highway (and noise). And the highway strip gave several options for food as well as easy access to the buses going to Rio Claro.

Quick Info About Doradal, Colombia

Doradal is a funny little town. It’s quite obvious that it is newly built, which makes you wonder why all these people decided to settle in the middle of nowhere between Medellin and Bogota.

My Colombian friend told me the town was settled by the workers of Hacienda Napoles, after Pablo Escobar’s demise. Today the hacienda is an attraction nearly as much as the Rio Claro Nature Reserve.

At the hacienda, Escobar built several attractions, including a zoo with animals imported from Africa. After the property was seized in the early 90s, most of the animals were transported to zoos around the country.

Unfortunately, the hippos remained and have developed into quite a nuisance since nearby conditions are ideal for their survival. You can read more about it here in this BBC article.

Trees and limestone rocks surround Rio Claro which has carved its way through the marble canyon.

Tips for Visiting Rio Claro Colombia

  • At first glance, the river seems calm. But there are strong currents throughout. Keep your wits about you and an eye on others in your group.
  • Keep all food sealed or hang it from a string so as not to attract unwanted visitors.
  • Payment for accommodations is due ahead of time. Within the reserve, only cash is accepted. The entrance fee is 15,000 pesos. Credit cards are accepted at the entrance, however, the credit card payment system is not guaranteed to work. The nearest ATM is 30 minutes away in Doradal, though it’s also not guaranteed to work.
  • A flashlight is needed after 5 pm.
  • Temperatures can drop considerably at night. Bring layers for cooler temperatures at night.

The Best Time to Visit Rio Claro

As the name implies, the river is crystal clear. Unless of course, you visit during the rainy season, which tends to stir up the sediments and create a muddy river.

The rainy season in Antioquia, Colombia is roughly April-May and September-November. 

If you can, you’ll also want to avoid weekends and holidays when the reserve is busy with families visiting from Medellin and Bogota. It’s possible during the weekend you will need to reserve the activities ahead of time or at least as soon as you arrive.

When I visited on Monday, there was no need to reserve right away and it made for a much more relaxed adventure.

Large rock stones line the bottom of the clear river. Plant life grows on top of the larger rocks in the center of the river.
