Usually snorkeling companies go to Manta Bay, which is in front of Broken Beach, because it is closer. You have around 80 % chance to see Mantas there, and there may be many boats chasing them. As soon as he spots one, the captain of your boat will probably urge you to jump into the water to get the chance to spend a few seconds with a manta, in the middle of all the other boats and snorkelers.
That is why some snorkeling companies started to bring snorkeling guests to Manta point. Less snorkelers and the divers are deeper ! But the best way remains to dive with the mantas even if it is your first time. We will be pleased to make you discovering diving with the manta rays ! It's really a great experience.
