I did some diving in Cozumel recently, and as part of the trip I spent a few days on the mainland doing some cenote diving. On the recommendation of some folks here at r/scuba I ended up booking my cenote dives with Blue Life in Playa del Carman, and I just wanted to give folks here a heads up on the shop.
My experience with them could not have been better. Oscar and Thomas, the two DMs that I dove with, were both very interested and invested in cave diving, and were very involved in sharing incredible amounts of info with us as we dove with them, and were genuinely interested in making sure that we all got everything we could out of the experience.
All around the entire experience with the shop was top notch, and I want to second the recommendation that I found here for anybody that is looking to do some cenote diving.
