Welllllll, seems that many people know this place as prizes are rising steep. Stay away, not for that reason vut because so many people for such a relatively small and isolated lagoon is way too much. Specially if they don't care that you use appropriate suncream or when it is overcrowded with beginners and cancun tourists who stand on coral... More

We had called here before in 2005, so knew what to expect. There are great numbers of fish, and underwater photos come out . there is fresh water at one end and salt water at the other and you can see the 2 mixing. The gardens are well laid out but it does et busy [and so it should] so... More

We love going here, this year makes three trips. We chose a day that was a little windy, which makes the ocean rough, but the lagoon was beautiful. The price is reasonable and the staff are friendly. If you want to spend the day, get there early and book a cabana so you have some shade.

We visited on day when the wind was blowing hard at Akumal Bay. We finished breakfast at Turtle Bay and decided to get our "snorkel fix" at Yal-ku. We were there at 9:03 - I believe the park opens at 9:00 - and snorkeled for a couple of hours, until the tour groups started to come in. This is great... More

This is a cool place to spend half a day if you are staying in the Akumal area. Short drive from Las Casitas. You need to either bring 'natural' sunscreen or be prepared to purchase sunscreen on site. Daily entrance fee is reasonable for access to a rather nice natural park setting with good snorkeling. Worth the extra $20 for... More

Found this place maybe a little over priced but nice amenities and a large area to snorkel. A few different types of fishes but nothing too exciting or any coral and such just rocks. Good for families and beginner snorkelers, was an ok way to spend the afternoon. Saw a large barracuda which was a little scary.

Save yourself the aggravation, buy their sunblock!!!! We thought we bought the right stuff (environmentally safe). They watched my wife and I put it on then told us to rinse it off because it will kill the fish! What a [--] move, they could have stopped us instead of waiting until we were covered!!

We never miss a trip to Yalku whenever we are anywhere on the Riviera Maya. Unlike snorkeling in the ocean, there is rarely any current in the lagoon. It is easy to get in and out of the water now that there are several stairways with railings. The park is beautiful as well, with stone paths throughout and several gorgeous... More

Okay, so maybe it's not the best snorkeling on earth, but the lagoon offers a very wide variety of beautiful fish in nice calm waters. It's true that you have to contend with quite a bit of "shimmer" from the mixing of fresh and salt water but there are plenty of pockets of clarity to see the fish, and the... More
