With temperatures averaging around 27 degrees Celsius (80 degrees Fahrenheit) year round and more than 100 species of tropical fish in the waters, the Bahamas are legendary for their snorkeling and diving opportunities. Half Moon Cay offers several snorkeling options: Guests can swim right off the main beach to a designated snorkeling area, and there are excursions by boat to prime offshore locations. If you don’t have your own mask and snorkel, it’s possible to rent them for the day.
