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

well, i had a great time on our tour of the sian ka'an biosphere with cesiak, and my friends felt the same. our guide antonio, was very knowledgeable and pointed out lots of little critters and birds along the way, as well as explaining the birds habits, and the tendencies of other creatures in the area. the tour cost $85... more

We booked through Cesiak in Tulum. My mother is an avid birder so we decided on the afternoon/evening birding tour. We arrived at the Cesiak office and were driven to the Reserve, picking up other visitors along the way. Our first stop was a cenote at the park entrance. We walked in and were told we had only a few... more

Hi! I live in Playa del Carmen, very close to Sian ka'an... and I love it!! In my experience, taking a tour is terrible... and go ther for a day, its wrong too... The best experience is driving for yourself (the road is really terrible, but it's better than 5 years ago) from Tulum to Punta Allen, spend tha night... more

We took the all day tour from Cesiak and liked it, didn't love it. Whatever failings it had weren't the staff's fault;; they picked us up very promptly at our hotel (we stayed on the beach at Tulum, so it was a very short ride to our destination, but I'm not sure it would be worth a longer ride from,... more

I've read some bad reviews of Sian Ka'an, which makes feel bad for the people that seemed to have just taken the wrong tour. When my boyfriend and I went there last year, we toured through Community Tours. I beleive that we did the Muyil and Float tour - it was awesome, we loved it! It's starts out pretty standard... more

Unfortunately we wasted one full day of our vacation at this 'place'. The excursion starts with a horrendous drive for 2.5 hours, approximately 1.75 hours of that is spent on a terrible gravel bumpy road through the jungle. We stopped once on the way to go into the biosphere. What did we see? a couple of hermit crabs, and a... more

My husband and I recently returned from a week in Pureto Aventuras, a beautiful and delightful place to stay. The one disappointment of our trip was a drive to the Sian Kaan to find a beach that we remembered from a trip a few years ago. We found the beach that was once pristine to be covered in trash and... more
