It is reached by boat, fast (two people, expensive) or slower (for groups, cheaper) sailing down the river La Pasión, habitat for turtles, birds and alligators. The environment is wild (long-sleeved clothing and mosquito repellent). The ruins form a complex with several points of interest. The guards can accompany you for a small tip. Care late in the afternoon, when the snakes start to leave (closed type shoe boots). A small adventure.
