This day trip far surpassed our expectations. It was truly amazing. I think it says a lot that a few of the people in our tour group were taking the tour for the fourth time. Our guide was incredibly knowledgeable and spoke very good English. There are other tour groups bringing groups to visit the Biosphere, but they are all... more

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

I confirmed the details THREE times, and NEVER received anything further. I tried to contact them for two... more

There are some tour operators that organize visits in the reserve. 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
