After the Acro Mundial (Guatemalan football match), we took advantage of the trip to Cobán, and went to the Grutas del Rey Marcos. We swam in the river, went canoeing, canopying and, of course, entered the heart of the mountain. The tour was fascinating, you see the cave with its different environments, stalactites and stalagmites hundreds of years old. Inside you can hear and eventually see the underground river that supplies the water attractions outside. 3m7j
