It's easier to get to the town of San Agustín and the Parque Arqueológico de San Agustín now than it was for the conquistadores, but expect to put a little effort into it.
By road:
From Bogotá to Neiva, capital of the Department of Huila, via paved national highway, about six hours, but be prepared for it to take longer. From Neiva to San Agustín is another four hours. From Popayan, by bus, it's also about six hours.
By air:
Either into Neiva’s Benito Salas airport or Pitalito’s Contador national airport. San Agustín is only 45 minutes by road from Pitalito. Check
flights from your area to Bogotá or other locations in Colombia. You can also browse for hotels and car rentals.

Once there, you can tour the site by 4x4, horseback or by foot. Horseback is a popular choice and allows you plenty of opportunity to enjoy the scenery. You can rent a horse in the town of San Agustín.
