Our First Ever SCUBA Dive in Casa Cenote, Tulum

There’s such amazing underwater stuff in Mexico that we thought we’d give diving a go. Fortunately, in Mexico, you don’t need any qualifications or experience or anything like that.

We dived in an underground cave near Tulum called ‘Casa Cenote’ which, compared with the incredible Gran Cenote we had snorkelled in, looked like a big black puddle from outside.

It was a bit scary being so far underwater (especially for Bert who is in the process of conquering his fear of deep water) but we both enjoyed it. Our instructor, Jorge, and Tania both got quite a shock when Bert´s goggles started filling up with blood, but Bert was fine – just a nose bleed brought on by pressure or something, we figured.

Well, apparently, our ‘Discovery’ dive was actually the first day of a PADI course. We learned to do the following underwater-

1. Remove respirator from mouth, breath out through mouth for a while, replace respirator (this was the most nervewracking bit)
2. Let go of your two respirators, then recover them from behind you by moving your arm round in a big circle and putting one back in your mouth.
3. (Tania only because of Bert wearing contact lenses) Fill goggles with water, then fill with air again by blowing out your nose.
4. If someone panics and loses their respirator underwater, hold your second respirator out to them to take whilst putting your hand on their shoulder to keep them at a safe distance.
5. Lie flat in the water without going up or down.

This last point sounds easy, but I (Bert) found it completely impossible. You wear an inflatable jacket which you can put more air into, or let air out of. The idea is that you have the right amount of air so that you don´t either float or sink. I didn´t work out under after the dive, however, that I was actually controlling this with my mind. When I got nervous, I somehow changed my breathing and floated. When I was relaxed, I sank. So I spent the whole 90mins trying to compensate for my state of mind by pressing buttons to inflate or deflate my jacket. It never really worked and I spent quite a bit of time lying on the bed of the cenote looking like an idiot.

Tania was, needless to say, brilliant. The instructor, Jorge (George) said she had better breathing than he did. Typical.

We are glad we did it and it was an amazing place to do a first dive, once we got under the water.

Photos were taken by a professional photographer who dived with us.



  1. “fortunately you dont need any training or experience to Dive”??????????? You really did loose your fear of death didnt you!

    What am I talking about, I tried the same in Greece, I was just like Robert, all up & down! No pix tho

  2. Loved the clear cenote water too- but only tried snorkelling.
    Tulum was a lovely place- log cabin & hammocks on the beach. But agree about Cancun. At least most visitors only leave it on day-trips..

    • Ah, lovely to hear from you, Mr. Fisher! Tulum was fab and swimming with sea turtles was incredible – but not like the Galapagos when we were inches from them, four at a time in crystal clear shallow water. Keep tuned for Galapagos post… Diving was an experience but in the places we went, you could see so much with a snorkel, it wasn’t really worth it.
