What You Can Expect

Grand Cayman Seaworld Observatory - Shipwreck and Fish Feeding Show

Semi-Submarine Explorer

Make your way to the dock in the heart of George Town, where you'll board the Seaworld Observatory. Take your seat next to one of the many windows for a clear view of the underwater world. 

Visit the Cali, a steel schooner dating from 1900, which ran aground in 1944 just 100 yards (90 meters) off the coast of Grand Cayman. Continue on to Cheeseburger Reef, where a diver will jump off the ship and into the water to feed the fish. Watch out your window as the schools of friendly tropical fish swarm the diver. Get your cameras ready for some up-close shots of the Cayman Islands' wide variety of marine life. 

The Seaworld Observer will travel to the site of the Balboa, a freighter that shipwrecked in 1932. This 375-foot (115-meter) boat was broken into pieces on the ocean floor by the force of the waves during one of the worst hurricanes in the island's history. Parts of George Town were rebuilt after the storm using wood salvaged from the wreck. 

After an hour of viewing Grand Cayman's seascape, return to the dock in George Town and disembark.

This excursion was very enjoyable and laid back. We boarded the boat about 45 minutes after arriving at the meeting place. We both enjoyed seeing the ship wrecks, as well as the feeding of the fish. This is a glass bottom boat for fish obervation.

Really enjoyed this experience of seeing and being under the clear water in Cayman. Something we wouldn and #39;t have experienced otherwise since we do t scuba dive. Loved it.

The tour was excellent. The sub made a circuit that lasted about 50 minutes. Nice selection of critters in view and saw a couple of sunken reef/ ships. Great tour guide and ship crew. Knowledgeable and friendly.
Only hassle was the time zone- boat vs. local time so we almost missed our slot time and the requirement to have a printed voucher despite that is says electronic voucher is accepted.

Excellent. Great views from all windows. The fish feeding was a frenzy of activity and the diver was completely covered with fish to where you could hardly see him.
Recommend highly.
