Welcome to Grutas Rey Marcos
Near Aldea Chajaneb, 12km east of Cobán, is the cave system Grutas Rey Marcos. It's set in the Balneario Cecilinda, which is a great place to go for a swim or a hike on scenic mountain trails. The caves themselves extend more than 1km under the earth, although chances are you won't get taken that far. A river runs through the cave (you have to wade through it at one point) and there are some impressive stalactites and stalagmites. Headlamps, helmets and rubber boots are included in the admission price to the cave. According to local legend, any wishes made in the cave are guaranteed to come true.
