What You Can Expect

Seaworld Explorer Semi-Submarine

Seaworld Explorer Semi-Submarine

The Seaworld Explorer is a state-of-the-art semi-submarine developed in Australia for use on the Great Barrier Reef. The vessel does not submerge; you descend into the hull of this cruising underwater observatory and sit in air-conditioned comfort five feet below the surface of the water, exploring amazing sea life through large, clear glass windows.

Your journey begins as you board a transfer boat that takes you to the Seaworld Explorer, waiting near renowned Arashi Reef. Your skilled captain and knowledgeable narrator guide the semi-submarine through this wondrous reef filled with beautiful coral formations and hundreds of spectacular tropical fish.

Leaving Arashi Reef, the Seaworld Explorer takes you to the wreck of the Antilla, a 423-foot (128 meter) German freighter destroyed during World War II. The huge ship lies on her side in 60 feet of water where it is only partially submerged, providing a resting-place for the pelicans that frequent it. Measuring 423 feet in length, this is the largest wreck in the Caribbean.

A knowledgeable marine expert will provide you with information on the amazing underwater world around you and will be happy to answer questions. From the wreck, you enjoy a relaxing cruise to shore.

This was a new experience. Was a great experience viewing history of WWII. The fish including the two-legged ones were fun to watch.


5 star rating: Highly Recommended August 2014

It was a wonderful trip. Just long enough, not too long. Tip: if you are a party of four or more, try to sit opposite each other, half the cool fish scene is on the other side, so cover your bases.

My boyfriend and I came to Aruba for the first time and wanted to explore the sea tour options. This tour was great for us as it was more on the affordable side and we got to see similar things that we believe we would have been able to see on a full submarine tour. The tour boat/submarine departed conveniently from the Palm Pier dock which was near the high rise hotels (walking distance) and since we were staying at the Marriott Surf Club it was just a 10min walk. The tour ran approx 2hrs and consisted of half the time on a boat ride above water and the other half on the semi-submarine ride which we got to see some of the deep water fishes, coral, and even a sunken ship! The tour guide was very friendly and funny and made the experience very entertaining for us. If you are looking for a nice leisurely water tour both above and below water this is the way to go!

This was a fun tour. The reef and sunken ship were cool. The tour now leaves from a different pier, so we walked a couple of blocks along the beach. I would definitely take this tour again.

Very Cool! My husband loves marine life, and he had a blast. Seeing the shipwreck with the sea critters was really interesting.

We were a bit skeptical after reading the comparison to the "full" submarine experience, but we can tell you without hesitation that we thoroughly enjoyed this Seaworld Explorer Semi-Submarine. The visibility could have been clearer over the coral reef, but that was due to weather conditions out of their control. Many large and beautiful fish came directly to the windows of the sub and the view of the German war ship was fantastic. This trip is worth the price -- in quality and the value you get for the price. Also great for anyone not sure if they want to be completely under water!

The submarine was very interesting and going over the wreck was fascinating! Didn't see as many fish as I would have liked to but all in all it was a good trip!
