First was Calica, a commercial port a few miles south of Playa del Carmen. There is nothing at the port except a few vendors with the usual trinkets for sale. In the afternoon, there was a Mayan dance group that was entertaining and pictureque. We chose to take the ship's excursion to Tulum. I highly recommend this tour if you have any interest in Mayan history and seeing well preserved ruins on a beautiful Caribbean location. My wife, who is not a history buff, thoroughly enjoyed learning about the Mayan culture. Our tour guide,Cesar, spoke Spanish, English, and Mayan. The Mayan language sounds nothing like Spanish, and has more roots in Asian languages; as do the physical traits of the Mayans. If you take a video camera, there is a nominal charge of $4.00. It is well worth the fee to take videos. To really get a feel of the size and beauty of the site, a video is the best method of recording the magnitude of the ruins and the beautiful views of the sea. The tour lasts about four and a half hours. At the end of the site visit, Cesar met us at the bus with a cold, wet facecloth, a bag of chips and a bottle of water. A DosEquis could be purchased for a few dollars from the bus driver or you could buy five for ten dollars at one of the restaurants at the site.
