Snorkelers should be comfortable swimmers and aware of boat traffic. The turquoise waters suggest good visibility, but marine conditions can change quickly. Check weather forecasts, observe warning flags, and consider hiring local guides for surfing or snorkeling, especially if unfamiliar with the area's specific conditions.
