Certified divers visiting Nha Trang have a chance to visit Ho Mun Marine Park. Go with a guide who will show you the best underwater sites. This tour includes pickup via a minibus from your hotel in central Nha Trang. You'll transfer to Trang Tourist quay, where you'll board a 52-foot (16-meter) boat—private speedboat charter is also available—and enjoy two dive/snorkel sessions. Lunch is made on board and served on the way back to the pier.
