I went here after trying to book three different boat trips out to a reef being canceled due to winds. Entry fee is only 9$ US and its a fun way to spend the afternoon. more

We went with Edventure Tours to this place, but it's very reasonably priced. It was only $9 USD for adult tourists to get in; even cheaper for locals. The lagoon is beautiful. You have to wander the paths through the gardens to get to the lagoon, which can be an adventure in itself. As I'm not a strong swimmer or... more

We had an awesome time, 4 hours straight of snorkelling because there was so much to see ( although we paid for it in sunburn- wear a t-shirt!). We had our own snorkels so the entrance fee of $9 each was a cheap but very enjoyable day out . more

I loved this place so much i went back for a second look on my way to the airport. there are Tons of fish of a great variety in clear waters that sparkle where the warm and cold mix. you're better off swimming around the edges and rocks, where the fish'll hang out if there's more ppl there. I saw... more

We snorkeled at Yal-Ku July 2009 and found it a complete waste of money! The water was really cloudy, the walkways were sharp and painful to walk on, and saw very few fish. It's far away from Akumal & the main highway. Avoid this and snorkel at the main Akumal Bay instead.... more

Located at the very end of Akumal Beach, is the lagoon of Yal-Ku. Cold spring water mixes with warm salt water to profide a refreshing snorkeling experience. The lagoon is protected, the water water crystal clear, with an interesting effect caused by the mixing of the salt & fresh water, and there are plenty of fish and things to see.... more

I visited Yal-Ku on the recommendations from TA, and couldn't be more pleased with the experience. My wife and I hired a private guide for a day to experience the Akumal area. I highly suggest combining a trip to Yal-Ku Lagoon with a shorter stops at Cenote Azul and Akumal Bay. Yal-Ku Lagoon is a beautiful site. It wasn't very... more

I loved Yal Ku lagoon. It wasn't very crowded, and we were able to see a lot. We were there about 2 hours. Plan to wear a shirt in the water! They don't allow sunscreen (not even the "eco-friendly" kind) so bring a shirt. I didn't have one to wear in the water and burnt my back. Also, we wasted... more

We went to Yal Ku at the end of two days of snorkeling in the ocean, cenotes and at Xel Ha (see review on this board). Overall, for us, you could argue that this was the best of the lot. The area is very compact, and if you stay toward the left (away from the ocean) you will see a... more
