Nha Trang is a popular seaside resort known for its palm-lined white sand beaches and clear turquoise water. Snorkeling and scuba diving is excellent-as is the nightlife along the strip of oceanfront restaurants, bars and cafes. Life in this Southern coastal city centers around the beach, of course, so take a boat trip and discover the small, isolated islands where you can stop to explore hidden coves and swim in crystal-clear water.
