I've always wanted to try scuba diving, though I've never had the chance. I think it would be amazing to see all the fish and wildlife in the ocean. I hadn't heard about the shipwrecks, I would imagine that is an amazing sight underwater. I'm going to look into taking a diving class down there and maybe one of the group diving trips you mentioned.

If you want to scuba dive in Aruba, you need to take the Mi Dushi Tour. It is an authentic sailing ship which still sails the waters of Aruba. You can tour the ship, sail on the ship and go on scuba adventures.
