Top Vietnamese Islands to Visit
Vietnam’s islands stretch from the southern tropics to the far north, each with its own personality. Here are the most popular picks:
Phu Quoc Island (Đảo Phú Quốc)
Vietnam’s largest island sits in the Gulf of Thailand and offers a full mix of resort luxury, nature, and lively local life. Its west coast is lined with long golden beaches like Long Beach and Sao Beach, backed by palm trees and clear blue water. Beyond sunbathing, you can explore the island’s authentic side — Duong Dong night market for seafood feasts, fish sauce factories that made Phu Quoc famous, and the world’s longest over-sea cable car to Hon Thom island.

- Best time: November–April (dry season)
- Activities: Snorkeling, diving, cable car to Hon Thom, seafood feasts
Con Dao Islands
Once known for their grim past as a colonial and wartime prison, the Con Dao archipelago has transformed into one of Vietnam’s most peaceful island getaways. Located off the southern coast, it’s now a protected marine area with pristine beaches, coral reefs, and nesting sea turtles. You can dive or snorkel around Bay Canh and Hon Tai islands, hike jungle trails in Con Dao National Park, or watch baby turtles hatch on remote beaches between June and September. History lovers shouldn’t miss Phu Hai Prison and Con Dao Museum, which reveal the island’s tragic yet powerful past.

Cat Ba Island
The gateway to Lan Ha Bay, Cat Ba combines limestone cliffs, emerald waters, and jungle-covered hills. While many visitors come for kayaking and cruises through the karst scenery, the island itself is worth exploring — Cat Ba National Park offers scenic hikes to viewpoints like Ngu Lam Peak, and the Hospital Cave provides a glimpse into wartime history. The waterfront town has plenty of affordable hotels and seafood restaurants, while nearby beaches (Cat Co 1–3) are good for swimming. You can also book a cruise through Lan Ha Bay — quieter and less crowded than Ha Long Bay — with options for overnight stays on traditional junks or eco-boats.

Cham Islands
Just 15 km off the coast from Hoi An, the Cham Islands are an easy day trip or overnight escape. The archipelago of eight small islands is part of a UNESCO Biosphere Reserve, known for its coral reefs and relaxed fishing villages. Visitors come for snorkeling and swimming at Bai Chong and Bai Ong beaches, eating fresh seafood, and enjoying simple life with no high-rise hotels. Electricity is limited, which adds to the charm. Most tours include a short boat ride from Cua Dai port, snorkeling, and a beach lunch.

Ly Son & Nam Du Islands
Known as Vietnam’s “Garlic Island”, Ly Son sits off the Quang Ngai coast and still feels distinctly local. Formed by ancient volcanoes, it features dramatic cliffs, lava fields, and quiet beaches like Hang Cau and To Vo Gate, a natural rock arch perfect for sunset photos. Ly Son is a place to rent a scooter and circle both islands (Big and Small Ly Son), stopping at garlic farms, shrines, and fresh seafood stalls. Few foreigners visit, so expect simple accommodation and authentic hospitality.
Nam Du: Cluster of untouched green islands, growing with local adventure seekers. Rustic home-stays, scooter rides, and simple beaches.
