You have no worries, the water is clear and beautiful at the bahia! The rocky area is where people don't even swim (right at the AKumal beach hammock location. I was there in August and it is breathtaking! I loved it there and the resort was amazing. I do agree that the beach could be better because it was kind of small but it was so calm and clear and you could swim with fish by the dock that it didn't even bother me. They have areas sectioned off to protect the coral reef so it was understandable that we were limited to where we could swim! I also have been looking for other resorts that had nice long white sandy beaches with blue water but the pictures look so plain and simple! Something about having the option to have those rocky pictures make them look more artistic, romantic and interesting. Everyone has their own preferences so whichever resort you choose (including the Bahia) you will have gorgeous pictures! You're in Mexico theres beautiful beaches everywhere Good luck with your decisions <3
