Known as Colombia’s inland sea, Prado in Tolima offers a striking combination of mountain scenery, open water and outdoor adventure. The Dario Echandia Reservoir covers about 4,200 hectares, or 42 square kilometers, with green mountains surrounding its waters and creating a landscape that feels far removed from the Andes.
Visitors can explore the reservoir by boat, swim, water-ski, canoe and try wakeboarding. Cabins, condominiums and camping areas also offer options for staying near the water. Located about two hours from Ibague, Prado is accessible enough for a long weekend.
But the destination is more than a scenic getaway. The reservoir was created as part of a major hydroelectric project, and its history, rock formations and secluded spots have become part of the boat tours that introduce visitors to the area.

How the reservoir became Colombia’s inland sea
The reservoir was built to produce electricity. Construction began between 1959 and 1961, and the dam began operating in 1972. German and Japanese companies directed the project, while Colombian workers carried out much of the construction.
The reservoir stretches about 28 kilometers from south to north and reaches a maximum depth of 90 meters. The Cunday and Negro rivers, along with numerous streams, feed the lake, whose waters form part of the Magdalena River basin.
The associated hydroelectric plant has a capacity of about 51 megawatts and supplies electricity to parts of Tolima and Huila, as well as Girardot. The plant is currently managed by Celsia. Tourism arrived later, as the reservoir’s size and scenery turned the area into a popular destination for recreation and water-based activities.
The reservoir also supports wildlife and local livelihoods. Official information describes the area as a suitable habitat for plants and animals associated with warm climates, while local fishermen work the waters, particularly for tilapia. The combination of energy production, wildlife and recreation has made the reservoir central to Prado’s identity.
What to do at Colombia’s inland sea and how to get there
Most visits begin with a boat tour because many of the area’s main attractions are located around the reservoir and are accessible by water.
Boat tours can include stops at Laguna Encantada, or the Enchanted Lagoon, a pool surrounded by tall rock formations. Local tradition holds that the lagoon always maintains the same water level. Another stop is the Laberintos de Yacupi, a series of rock passages formed by a geological fault, where visitors can photograph the landscape and look for birds.
Other attractions include the Cueva del Mohan, a small cave with a narrow opening through which light and water enter; the Canon de los Enamorados; and the Cascada del Amor, a 12-meter waterfall accessible by boat. Visitors can swim in the natural pool beneath the waterfall.
The Isla del Sol, which is shaped roughly like a C, is the largest island in the reservoir and is home to about 200 residents.
For visitors looking for more active pursuits, the reservoir also offers jet skis, inflatable rides and paddleboarding.
To reach Prado from Bogota, travelers can drive south through Soacha and follow National Route 40 through Girardot, Espinal and Saldana before taking the signed turn toward Prado. The final stretch takes about 30 to 40 minutes and leads to the pier, where boats depart for hotels and other destinations around the reservoir.
Travelers without a car can also take a direct bus, with the journey from Bogota taking roughly six hours.
