A day on the water
The reef lies several miles out in the open sea, so every trip starts with a boat ride. Morning trips usually have the calmest water. Many boats stop at two different reefs, so you see more fish.
In the afternoon, many trips add a sunset sail, kayaking in the mangroves or a stop at a sandbar. If you want the best view of the corals, choose a morning trip.
Closer to Miami, Key Largo snorkeling takes you to the reefs of the underwater park.
