This scuba dive, wow. Cenote Angelita in Tulum, Mexico was amazing. First off, it’s a deep one at 34m (100ft). Secondly, there is a 10 foot thick layer of Hydrogen Sulfide at 30m you are able to pass through. Hydrogen Sulfide is poisonous, and heavily smells of rotten eggs. (I couldn’t show you that part in the video). Once through, it turns into a night dive, and you need to use your torches. You only have a few minutes beyond the layer before you have to start ascending again. It’s a murky landscape, with petrified trees sticking out of the cloud. Mayans believed that cenotoes were the gateway to the underworld, and yeah, after visiting this one in particular, I can see why.

This was probably one of the most advanced dives I’ve done. It’s not technically difficult, but it is a mental challenge. It’s not uncommon for divers to panic a little bit and have difficulty passing the layer. Like always in diving, keeping a calm mind is the most important thing. Anyone can do this dive, it’s just remembering to breathe, and realizing you’ll be fine.

There are a lot of cenote cave dives scattered all through Riviera Maya, Quintanaroo and Yucatan. I was lucky do quite a few during my travels here. I thought that I wanted to get my Cave Diving cerification, but realized that “Cavern” diving (when you can still see ambient light) is all I really wanted. You just need to have an advanced cert.

It was the most exhilarating dive I’ve done yet, I’m not sure if there is anything else like it on the planet. Go in and get wet.

Hey Mike. Love the footage you’re posting lately with your new Sony A7s. I’ve been torn between the A7ii and the A7s. Do you think the lowlight capabilities of the A7s make for a better underwater camera? Thanks mate.

Angelita is an absolutely amazing dive site. Definitely one of the “must see” cenotes as you feel as if you are diving in an 80’s horror flick. If you are interested in diving a cenote yourself you can check out the Cthulhu Divers website. It has all the info you need to help you choose the best site for you –
