We visited Yalku the day after Christmas. It was really an amazing place - the water is beautiful and teeming with fish.
Our daughters, who are 4 & 6, went with us and had an fairly good time. I would really recommend NOT taking little ones who haven't snorkeled before as even with the stairs leading into the water it really is tough getting them in and out of the the lagoon with gear on.
But this place really is not to be missed. We took a taxi out of Playa and even the driver didn't know where this place was actually located, but it was really easy to find.
FYI - apparently the snorkel gear is supposed to be included in the admission to the lagoon, which was about $7/each. However, they charged us extra for everything, including lifejackets for the kids. We easily ended up paying $20/person, so be aware that it's supposed to be included in the entrance fee.
Have fun! It's truly a beautiful spot for relaxation.
