Philippines
Fantastic diving, more soft corals than you can shake a snorkel at. Sea turtles galore, so many lion fish I stopped counting, frog fish, sea snakes, eels, eels, eels, spotted rays, angel wrasse, schools of fish everywhere, wall, and reef diving at its best!
Also a great side trip if in Manila is Anilao, in Batanges, Philippines. The resorts leave much to be desired, but the diving is phenomenal (think backpacker diving, go for the underwater sights, and hope the food at the resort is edible afterward, or be smart and pack a picnic), the diving is worth it though.
