Stretching for approximately 20 kilometers along Phu Quoc's central west coast, Long Beach (Bãi Trường) is the island's longest, most developed, and most convenient beach hub. This is where the majority of resorts, guesthouses, beach bars, and restaurants are concentrated, offering a wide range of options for accommodation and dining right by the sea. Its western orientation also makes it the prime location on the island for watching spectacular sunsets over the Gulf of Thailand.

Long Beach offers golden sands and generally calm waters suitable for swimming, especially during the dry season (typically November to April). Visitors can easily rent sun loungers, participate in water sports like jet skiing or kayaking (offered by various vendors and resorts), or simply relax with a drink at one of the many beachfront establishments. The long stretch is also perfect for leisurely walks or jogs along the shore, enjoying the sea breeze and the lively coastal atmosphere.

While perhaps not possessing the powdery white sand of Sao Beach, Long Beach's main appeal lies in its convenience, extensive amenities, vibrant atmosphere, and stunning daily sunset spectacle. Its accessibility from Duong Dong town and the airport makes it the practical choice for many visitors. It serves as the bustling heart of Phu Quoc's beach tourism scene (as of April 2025), offering everything needed for a comfortable and activity-filled seaside holiday.
