We took a full day tour with Cesiak which was a wonderful way to have a close, personal experience with the Sian Ka'an Biosphere Reserve. Our guide Antonio was exceptional.....spoke excellent English and was literally a walking encyclopedia of knowledge. His passion and exuberance were contagious! We walked in the jungle as Antonio pointed out plants and insects, including a... more

We went with Sian Kaan community tours (www.siankaantours.org a non profit organisation that puts money back into the conservation of the biosphere) and did the Punto Allen and Muyil Forest tours. The trips were excellent, with the guides having a real passion for the conservation of the biosphere. Their English was good and were able to answer all questions. We... more

We went with the cooperative even if they are more expensive, because the money remains with them (and help them stop cutting the trees or hunt in the reserve). We chose their 'Punta Allen Eco-adventure ' because it supposidly included: ' an hour of exploring the amazing underwater world... more

First, I want to say this trip was not a tour. We had our own rented Jeep and read about the drive in a vacation type book. We stayed in Playa Del Carmen, where we rented a villa for ten days which was wonderful. The Mexian ruins are a must see. Driving in to Punta Allen is easy even for... more

We walked in and were told we had only a few... more
