Diving with bull sharks is one of the many activities you can do in Playa del Carmen, a beach town near Cancún in Quintana Roo, México, on the Caribbean coast.
I went with PlayaScuba, where I did my diving course.
It was really great! The sharks were already there when we got there - 9 of them! The bull sharks were usually female sharks who were pregnant, just waiting around before moving on to somewhere else to give birth. They were tranquil and just swimming around us.
It was an absolutely surreal experience.
