Scuba diving is a popular water activity to partake in when you're in Galle. The waters around Galle are teeming with marine life, from crabs to blue whales and everything in between! If you are PADI certified, the waters here are the best to explore through. However, for the less experienced, snorkelling is also possible in Hikkaduwa. With a natural reef that is home to a wide variety of marine creatures, snorkelling is a rewarding experience that will keep you busy for hours! An ideal time to go snorkelling in areas like Unawatuna, a short drive from Galle, is between the months from November to May. You'll be able to spot moray eels, sea turtles, parrot fish and plenty of other reef fish. The beaches of Sri Lanka are known to be home to 5 different species of turtles; all of which have been listed under the Endangered Species category.
