Cayo Largo - Lagoon
Best time during the dry season from November to April, but this time is also the peak season. Shoulder season May and June is worth a try and less crowded. Showers may occur, more often in the night or at the morning.
Cayo Largo is a year round destination. The advantage of the dry season it is less hot and fewer mosquitos. We travelled to Cayo Largo in June and got bitten everywhere. Anyway our stay at Cayo Largo was fantastic. Snorkeling is outstanding. We even discovered two huge sharks and a stingray but unfortunately my brother borrowed the gopro for diving. Don't miss the full day catamaran tour. It was the highlight of our vacation. We got delicious crayfish for lunch and spent some additional time in a beautiful lagoon.
