Two weeks ago we booked the Tropic Air tour from San Pedro to Xunantunich and Cahal Pech. Our guide was an archaeologist named Mark McField. This was far and away THE best interior tour I have ever had the pleasure of being part of. He is so knowlegeable, not only of the sites mentioned, but the flora and fauna as well. We had lunch at Clarissa Falls, a place I would have driven past and never seen otherwise. It has a great history all it's own and the food is not to be missed, just wonderful. His tour company is ALUX ECO (pronounced AL-OOSH) and his cell # in belize is 223-2130. He also does tours of Lamanai, Tikal,& Caracol as well as the caves, zoo, and Mountian Pine Ridge.This wonderful day trip included the round trip flight from San Pedro, transportation to the sites, lunch, and admission to both parks. Don't miss this one.
