This exiting underwater cave is great for diving and snorkeling. It got its name from the 1965 James Bond spy film "Thunderball," which was filmed here. In 1983 it was the site for another Bond movie "Never Say Never Again”. You can see here lots of colorful corals and fish. There are several entries where you can swim through the holes to get inside the cave. Some of these holes are underwater but easy to pass through. The water is very bright and clear so you can fully enjoy all the corals and fishes.
