This week's episode of Travel Today with Peter Greenberg comes from Paradisus Playa del Carmen La Esmeralda in Playa del Carmen, Quintana Roo, Mexico. Joining Peter Greenberg this week is Historian Tiziana Roma, with a report on the real story behind the Mayan ruins and their physical foundations as well as the state’s ports. Roberto Diaz, President and Founder of the Underwater Museum of Art (MUSA), shares the history of this special subaquatic museum and its mission to save the coral reefs, plus a report on how much marine life has returned to the permanent sculptures installed below the surface. And Otto Von Bertrab, the General Director of Rio Secreto, shares the story of how he discovered Rio Secreto and why it took him almost a year to traverse all 31 miles of the semi-flooded, underground cave. There’s all of this and more when Travel Today with Peter Greenberg comes from Paradisus Playa del Carmen La Esmeralda in Playa del Carmen.
