The main beach of Phu Quoc, stretching nearly 20 km along the western coast south of Duong Dong. The northern section, nearest the town, is the most developed — beach bars, restaurants, and resort pools line the road behind the sand. Further south, development thins out and the beach becomes quieter.
The sand here is not as fine or white as Sao Beach, and the water is calmer but slightly less clear. The sunsets are long and spectacular, the western orientation giving unobstructed views over the Gulf of Thailand. Long Beach is the most convenient swimming beach for visitors staying in or near Duong Dong. Water sports (kayaking, kitesurfing) are available at multiple points along the beach.
