Like many reviewers, we too wanted somewhere to stay that would allow us to get a head start on the 60 km drive to the actual ruins of Calakmul. We were a little put off by the price of Hotel Puerto Calakmul which is at the turn off from Hwy 186 towards Calakmul so decided to drive the 7 km down the road and give camping at Yaax'che a try.
For $11 each, we were given a large tent with two air mattresses. Each tent is placed under a protected canopy of sheet metal and thatching and the ground underneath is cleared of rocks and other hard objects that would make sleeping uncomfortable.
There was a clean ecotoliet onsite (urinal drains into a bucket that can be emptied by the staff and the toilet was a long drop toilet which you would put a few scoops of sawdust after you were finished to help with the smell). There was also a shower area, but to be honest we didn't shower so I am not 100% certain how it worked. I think you filled a bucket of water (provided) and did an old fashioned 'splash' bath.
We had brought our own food that we had purchased in Playa del Carmen prior to leaving since we weren't sure what the food situation was going to be like. Thus we did not eat here during our stay. They did have a table and chairs for guests to use for preparing/eating. As well as a large campfire area with seating. A group Spaniards were making 'grilled' slabs of ham and roasting wieners over the fire, which really made our tuna sandwiches look boring!
I think the key take away here is that you are camping. As for facilities, I think the set up here matches or is better than a lot of smaller state parks here in the states. The benefit is that the tent is already set up for you. You don't have to mess around with hauling one in, setting it up/taking it down. Plus you get a real air mattress instead of sleeping on the ground or foam pad which most people use when actually camping.
Our only complaint is that they do have chickens, roosters and 2 dogs. The dogs barked off and on throughout the night and the roosters got going at 4:00 am. I am a light sleeper so that woke me up right away. The jungle sounds don't phase us as we have spent extensive time in the jungles of South America, Central America and Africa. In fact our 'white noise' at night here in Chicago is a recording of the Africa jungle at night. To me, the jungle is one of the most beautiful and peaceful places on earth and to get to 'camp' there was an exciting experience.
