Parque Arqueológico del Caño
Parque Arqueológico del Caño information
Lonely Planet review
This is one of only two archaeological sites in the country that are open to the public. Its museum displays objects that were found nearby. There's an excavation pit in the park as well; it contains a burial site where five skeletons were found in the exact same position as visitors see them today.
The museum contains dozens of pieces of pottery, arrowheads and carved stones. The objects are believed to date from a culture that lived in El Caňo about 1500 years ago.
