There are a thousand ways and more for someone to explore a new culture or environment when they go on vacation. There are dances, shows, and lots of unique and exciting things to do almost anywhere that you can think of to go. If you are a fan of the unique, though, then there is no tourist destination that is better for your adventures than the bottom of the sea.
Wreck diving is exciting, fascinating, and can be very mysterious as well. For colors and excitement, though, a coral reef is top notch and there is no coral reef better to explore than the Great Barrier Reef.
