Visit the impressive Ke Ga Lighthouse (Hải đăng Kê Gà), the oldest and tallest lighthouse in Vietnam. Located on a small rocky island (Ke Ga Island) just off the coast, about 30-45 minutes south of Phan Thiet, this historic structure was built by the French in 1897.

Accessing the island requires a short boat or canoe trip from the mainland. Once there, you can admire the striking granite lighthouse, climb its internal staircase (check if permitted) for panoramic coastal views, and explore the rocky islet. It's a scenic and historic half-day trip from Mui Ne.
