I have been travelling to Isla Mujeres since the spring of 2007. My first dive ever was with Aqua adventures on a discover scuba dive. I came home and got certified and was on the fast track to OWSI. I finished in near record time Just over 6 months. Thats the fastest PADI will allow. Luckily I had quit my job that summer and was able to do nothing but dive. I have spent many months on Isla since that time, I consider myself a Isla aficionado. I have dived at least 50 dives with Aqua adventures the latest was the summer of 2009. I must admit the quality of the dive masters has suffered lately. If they still employ Wilbert, well Wilbert is awesome. The claim they are a front and send you with other operators is complete BS. I know the owner, Sonia, she is American and legit. Donna used to help her run it and did a great job. They own their own boat, permits, and gear. I would have only dived with Coral or Aqua Adventures but I guess Coral is gone. There may be other operators that are good but be careful. I saw someone mention seahawk...sketchy and not even a PADI operator despite the illegal use of the logo. I called PADI North America when I was last on the island to confirm who was and was not legit. Aqua adventures was, Sea hawk was not. PADI asked me to take pictures of the illegal use of their logo and send it to them. I did. According to Sonia they have complained before but little can be done. I would consider other operators on the island but buyer beware. If youre not a competent diver, you need to dive more! Yeah but really if youre not comfortable in your own skills dive with Aqua Adventures. Aqua's rental gear is pretty used, but I always bring my own stuff. My wife has rented thier gear a few times. Most rental gear outside of intense dive areas in MX seems to be pretty ...well used. If you know your stuff , have your own gear minus tanks, don't worry just get a operator that has good tanks and good air and a decent boat to take you out to many of the fabulous spots. As a certified diver you should always take care of your own safety don't rely on others. But if you have to or want to I recommend Aqua Adventures.
Isla is different than Coz, but in many ways it is just as beautiful. Manchones is chill and very nice 30 ft, tons of fish occasional nurse shark, rays, and turtles. Punta Sur has nice current loads of sea stars, an old galleon's anchor, cannon, and cannon balls. Punta Negra (Cancun hotel zone) is a great 70 foot reef with lots of life, media luna cool topography some current, and many others. Its a great place to dive. I never get sick of manchones, and I have been a spoiled diver so I don't compliment places easily. Diving on Isla is a great value and awsome experience.
I just have to say if you get the chance you MUST go down to Hidden Worlds Cenote park and Jungle tours just south of Akumal and dive the cenotoes dos ojos, bat cave, stomach of the snake, they are unreal. I had been to the Yucatan dozens of time before I did the Cenote Dive. WOW! what a dummy I was. It is worth the time, money and "hassle". I will be back diving them in just over a month! Can't wait. If anyone ever want travel advice to Isla I am happy to provide it just shoot me an email.
