Parque Arqueologico is San Agustin's main attraction. It features several ancient burial sites, a lot of statues and a small museum. It's 3 km west of San Agustin and can be reached by frequent minibusses.
The San Agustín Archaeological Park is a large archaeological area located near the town of San Agustín in Huila Department in Colombia. The park contains the largest collection of religious monuments and megalithic sculptures in Latin America and is considered the world's largest necropolis. Belonging to the San Agustin culture, it was declared a UNESCO World Heritage Site in 1995. The dates of the statues are uncertain, but they are believed to have been carved between 5–400 AD. The origin of the carvers remains a mystery, as the site is largely unexcavated.

Far less visited, a bit smaller, but equally impressive as the archaeological park. The views from the park are amazing. There is no transportation to and from San Agustin, only to San Jose de Isnos.
Within easy walking distance are the four small sites, El Tablon with several statues; La Chaquira, carved rocks dramatically set overlooking the valley of the Rio Magdalena; La Pelota, with some coloured statues in excellent state and El Purutal. These can easily be visited in one day walking.
Other archaeological sites are Alto de Las Piedras, Alto de las Guacas, Alto del Mortiño o del Tigre, Granada, El Jabón, Lavaderos o Naranjos and La Parada
