Nam Du Islands, Vietnam

    Off the Southwest Coast of Vietnam in the Gulf of Thailand, Nam Du is a group of 21 tropical islands that form an archipelago. The Nam Du Archipelago and its islands are a popular vacation spot for Vietnamese nationals. Kept secret from outsiders, those who wish to visit may only do so if they are a resident of Vietnam and have an entry permit.

    Well-known for its stunningly blue water, deep green forests, and white sand beaches, the Nam Du Islands are one of the most beautiful destinations in Southwest Vietnam. With limited infrastructure throughout the archipelago, some islands have overnight accommodation and others are uninhabited. Most tourists will head to the largest island, Hon Lon, before hopping to the neighboring isles.

    Of the 21 islands in the Nam Du (Vietnamese: Quần đảo Nam Du) Archipelago, only 11 are inhabited full time. Larger in size and having overnight accommodations, Hon Lon acts as the main base for tourists. Officially part of the Kien Hai (Kiên Hải) District in Kien Giang (Kiên Giang) Province, there are two communes in the archipelago: An Son (An Sơn) and Nam Du.

    The closest major city to Nam Du is Rach Gia (Rạch Giá), which is on Vietnam’s mainland. The city is 83 km (51 mi) to the east of the archipelago while Phu Quoc, another famous island in the Gulf of Thailand, is 40 km (24.5 mi) to the northwest. Boats and ferries are the only methods of transportation to get to the Nam Du Islands.

    Tourists can leave from either Rach Gia or Phu Quoc (Phú Quốc) Island, though the former is the most popular choice. Tourists can also fly from Ho Chi Minh City (formerly Saigon) before purchasing tickets for a speed boat or ferry. Taking 2.5-3.5 hours from the harbor, boats and ferries depart once a day from Rach Gia.

    Not much is known about the history of the archipelago, which may be in part due to the lack of foreign tourism and investment. What is known is that the islands have been an important source for local maritime and fishing industries for centuries.

    Individuals living on the island have always relied on the sea and there are a few traditional fishing villages still thriving in Nam Du. A more recent development, tourism has led to the development of Hon Lon and the other 10 inhabited islands over the past decade, making it a hotspot for local and national tourists.

    Boats are the only way to get around the Nam Du Islands and depending on which one you visit, transportation options will range from walking to motorbikes. While visitors can rent or hire a motorbike on Hon Lon, many of the smaller islands will have very few roads and limited infrastructure. Uninhabited islands will require guests to go around by boat or simply walk.


    The Nam Du Islands have a tropical monsoon climate, which means that there is a wet and dry season. Unlike some of Vietnam’s island destinations, tourism in Nam Du is year-round. Although, most travelers would prefer to explore the archipelago during the dry season, which begins in November and lasts until early April.

    These months tend to be dry with clear skies and cooler temperatures. With the perfect weather, December to March are the busiest times for tourism in Nam Du. However, many tourists will brave the wet weather to cool off on Nam Du’s spectacular beaches. Keeping in mind that the rain can make travel difficult, temperatures will also be higher during the rainy season.

    An archipelago in Southern Vietnam, the Nam Du Islands are a stunning destination for those who are granted access. Perfect for individuals looking to spend time hopping around both inhibited and uninhibited landscapes, these islands are the perfect vacation spot for Vietnamese nationals and residents.
