[visited in April 2022]

Based in the town of San Agustín, it is quite easy to reach the three sites indicated as WHS. A two-day ticket for the entire archaeological area is on sale and can be purchased at the Museum located at the entrance to the San Agustin Archaeological Park, which can be reached on foot from the town along an asphalted road.
This is undoubtedly the largest and most interesting site of the three and worth a day's visit.

The next morning I visited the other two sites: Alto De Las Piedras and Alto de los Ídolos, they are in Isnos and a ride by car is required to reach them. Less extensive than the main park of the previous day, especially the first, but in my opinion they are both worth a visit and you can do it in half a day.

In the afternoon I visited other sites around the town of San Agustín which, although excluded from UNESCO heritage sites, absolutely deserve attention: in particular La Chaquira, La Pelota and the nearby El Purutal (the last two for a fee because not included in the official ticket ). Very pleasant visit, I recommend to do it on horseback, it is an itinerary of 4/5 hours in total.

The level of care and maintenance of the entire archaeological area is truly commendable: really excellent!
