We recently enjoyed the all day canal tour offered by Cesiak. Our tour guide, Miguel was one of the best tour guides I've ever had and was extremely knowledgeable about everything from the history of the area to the plants and wildlife that call it home. I couldn't imagine visiting Tulum without taking the opportunity to enjoy the relaxation and... more

We took the all day canal tour, which seemed costly, but I am so glad we did it. The best part of the trip, and what really made it worthwile was our guide, Miguel. He was so passionate, interesting and knowledgeable. Hearing him talk about everything was the best part. He was very patient about answering our questions as well.... more

For the second year in a row we took the Cesiak tour through the biosphere - a great boat ride across the flats into the mangroves and then a "float" down a Mayan canal. Crystal clear water, lots of birds, and in March no bugs at all. The guides are good and the experience is one of the highlights of... more

Tour was very easy to arrange, transportation excellent, on time and air conditioned. Tour guide (Tania) was very knowledgeable about Mayan customs and spoke excellent English, Spanish and Mayan. Took a tour for the day, leaving around 8:30 am and returning 5:00pm. Covered Mayan ruins, jungle tour from ruins to lagoons, boat trip to a refreshing 40min float down a... more

I stayed at CESiak the last week of February, 2009, and had a wonderful time there. Staff were unfailingly friendly and helpful, and the food was fresh, tasty, and filling. Tour guides were very knowledgeable and had a passion for their job. The lodging was clean, comfortable, and well appointed. (I presume those reading this review know that these are... more

My boyfriend and I decided last minute to sign up for the Sunset birdwatching tour of the sian ka'an preserve. It was wonderful, and if you're going to Tulum add this tour to your plans...it costs $70usd pp, and they pick you up outside your hotel if you're staying on the tulum strip. I don't want to give away all... more

My friend and I chose to do the Canal Tour with CESiak and were so glad we did. Our guides were absolutely wonderful, just really nice guys and extremely knowledgeable. The boat ride was fun, seeing the small Mayan trading outpost was unreal (some of the original paint remains!), and snorkeling down the canal was just crazy cool and relaxing.... more

Waking up to the sound of crashing waves, running down a sand dune onto a sundrenched, empty beach.. I felt like the luckiest girl in the world and it hadn't yet turned 7am! I normally avoid early mornings but in Cesiak the sunlight streaming into our beautiful tent proved difficult to resist. After a run, I would tuck into some... more

CESiaK itself is an extremely comfortable, pleasant place to stay. The buildings are all new and spotlessly clean and comfortable. It boasts 15 cabana-style rooms, some "doubles" (each with one queen sized and one single bed) and some "deluxe" (which apparently have fancier furniture, although they look the same from the outside.) All the cabanas have porches with chairs, hammocks,... more
