The Diving at Tubbataha is truly world class. In addition to barracuda and jack fish schools, we had turtles, napoleons, moray eels, sweet lips, white tips and grey reef sharks. These are also the things that you will see for sure. White sharks were on every other dive and sometimes 5-10 at a time.
The Park is great for children, adults get a bit bored I'd say. The place isn't too big, takes about an hour to walk through. I liked the glass tunnel where you can see all the fish from the bottom.
