Guides charge 200 pesos for a tour for one to six people. A better option is to find a copy of the green booklet San Gervasio, sold at local checkout counters and bookstores, and tour the site on your own. Seeing it takes 30 minutes. Taxi drivers offer transportation for about 330 pesos, which includes the driver waiting for you outside the ruins.
