First the diving in Turks is amazing. Due to the dive shop at the resort, we didn't get to go out a lot as it seemed they found any reason not to go. When diving in Turks, it's not will you see sharks, but how many on each dive.
It may not look like it, but this is the biggest shark I have ever seen in the ocean.
When diving in Turks and Caicos, its not if you will see a shark, but how many. These things were everywhere.
