Guayabo National Monument Review

On the slopes of Turrialba Volcano lies Costa Rica's most significant and only true archaeological site. Records mentioning the ruins go back to the mid-1800s, but systematic investigations didn't begin until 1968, when a local landowner out walking her dogs discovered what she thought was a tomb. Archaeologists began excavating the site and unearthed the base wall of a chief's house in what eventually turned out to be the ruins of a large community (around 10,000 inhabitants) covering 49 acres, 10 of which have been excavated. The city was abandoned in AD 1400, probably because of disease or war. Guided tours (about two hours) in Spanish or English make the stones come alive, with knowledgeable guides from the U-Suré Guide Association (the name is the indigenous word for house). Starting from the new, round, thatch-roof reception center, they'll take you through the rain forest to a mirador (lookout) from which you can see the layout of the excavated circular buildings. Only the raised foundations survive, since the conical houses themselves were built of wood. As you descend into the ruins, notice the well-engineered surface and covered aqueducts leading to a trough of drinking water, which still functions today. Next you'll pass the end of an impressive 8-km (5-mile) paved walkway used to transport the massive building stones; the abstract patterns carved on the stones continue to baffle archaeologists, but some clearly depict jaguars, which were revered as deities. Excavations in 2013 have begun to unearth an elaborate system of agricultural terraces. Guayabo has been recognized by the American Society of Civil Engineers as a feat of Latin American civil engineering second only to Machu Picchu. (On that topic, though, this is not Machu Picchu, and facilities at Guayabo are nowhere near as developed.) The hillside jungle is captivating, and the trip is further enhanced by bird-watching possibilities: 200 species have been recorded. There's a souvenir hut opposite the entrance, a pleasant picnic area, and brand-new, modern restrooms in a replica of a thatched indigenous hut. The access route from the east via the Santa Teresita (Lajas) has some rough spots, but you can make it in any car. The alternative Santa Cruz route is a little rougher, but you can still make it in a regular car, unless the road is wet—in which case you may need a 4WD vehicle to get here.
