Unmissable for its wealth of statues, the Parque Arqueológico, which was declared a UNESCO World Heritage Site in 1995, sits 2.5km west of San Agustín. The park contains over a hundred stone creations, the largest concentration of statues in the area. Many of them are left as they were found, linked by trails A, B and C, while others, like the ones in the wooded sector known as the Bosque de las Estatuas, are rearranged and linked by an interpretative trail. The statues are beguiling – their fanged faces, the animal-human hybrids, the stylized animal carvings – and they are all very much intact, though their purpose remains a mystery. Don’t miss the Fuente de Lavapatas, a maze of terraced pools, covered with clearly visible images of reptiles and human figures, thought to have been used for ritual ablutions. Further along, and up, is the furthest point of the park, Alto de Lavapatas, the oldest of the sites, with statues sitting forlornly on a hilltop, their brooding gaze sweeping over the countryside.
There’s also a Museo Arqueológico featuring pottery, jewellery, smaller statues and background information on the San Agustín culture; visit it before hitting the statue sites if possible.
