Best for Snorkeling and Scuba by iam1wthee
Just about every place we passed along the beaches had fish. Even if you are not good at snorkeling and scuba, if you just stick your head into the water you will see fish swimming below you.
The waters can be a bit rough in December and I do not recommend begginners during that time.
