The Cave of Wonders is located on the road between San Pedro de Macoris and La Romana. It has paintings and engravings on the walls made by the Tainos Indian. The tour is given for about 300 meters inside the cave and 25 meters underground. The tour ends visiting a sanctuary of iguanas. The price of the ticket is 300 Dominican pesos or about $6.50 dollars. I recommend you to visit the cave if you are near by because it has beautiful paintings and engravings that are part of the history of the country and you can only see them in person because they don't allow you to take pictures of the paintings and engravings.
