Which feature on Castaway Cay allows guests to snorkel and view marine life?

• A. Snorkel Lagoon Observation Deck.
• B. Underwater Trail of Fishes.
• C. Glass-bottom Boat Ride.
• D. Snorkeling opportunities at Castaway Cay (snorkel lagoon and related rentals).

Answer: (D)

Snorkeling opportunities at Castaway Cay, with the snorkel lagoon and gear rentals, provide the direct way to snorkel and see marine life. The snorkel lagoon is a calm, shallow area set aside for guests to enter the water and observe fish, coral, and other underwater life up close. Being able to rent masks, fins, and other gear on-site makes snorkeling accessible to beginners and families, which is the core idea behind this feature. Other options might offer different ways to view underwater life from the surface or through a guided ride, but they don’t provide the in-water snorkeling experience with immediate gear access in a designated lagoon, so they’re not as fitting for the question.
