Top Islands in Vietnam: Where to Go and What to Expect

Islands in Vietnam range from sparsely inhabited reefs to well-equipped resort islands, offering options for relaxation, snorkeling, hiking, and local food. This article lists notable islands from the north to the south and explains how to reach them, what to expect, and which type of traveler each suits.

What the islands are and how they fit into Vietnam’s coastline

Vietnam’s long coastline includes dozens of islands and archipelagos that vary widely in character. In the north, islands tend to be quieter, with rugged shorelines and small communities; central islands often sit close to popular heritage towns and are reachable by short boat trips; in the south you’ll find larger, more developed islands with airport links and a wider range of services.

Many of these islands are valued for clear water, coral habitats and seafood-dependent economies. Some islands retain only basic visitor facilities because tourism developed only recently, while others have large resorts and theme-park infrastructure. When you plan, consider the island’s region, level of development and transportation options.

Key islands and highlights

Co To (Quang Ninh) is an archipelago known for pale sand and open sea in northern Vietnam. It has dozens of islets and remains relatively undeveloped compared with coastal resort towns, which is why many domestic holidaymakers head there in summer for seafood and quiet beaches. As tourism is only now expanding, high-end services are limited.

Cat Ba (Hai Phong) is one of the larger northern islands, bordering major bays and offering beaches, a national park, and historical sites. It’s commonly combined with boat trips in nearby bays and has several small sandy coves, as well as military-era viewpoints and a network of caves and trails.

Cu Lao Cham, often called Cham Island (Quang Nam), lies off the heritage town of Hoi An. It’s a group of islands with marine protected areas and is a popular quick excursion from Hoi An or Danang for snorkeling and short beach stops. Day trips typically include a boat crossing, time ashore and opportunities to view coral life.

Ly Son (Quang Ngai) is an island group further down the central coast noted for volcanic rock formations and extensive garlic cultivation. The main island and a smaller neighbouring islet have beaches and hill viewpoints. Local cuisine emphasizes island-grown garlic in seafood dishes.

Off Nha Trang’s shoreline, Hon Tre (Khanh Hoa) hosts a large leisure complex connected to the mainland by a long over-sea gondola. The island also offers hiking routes, beaches for water sports, and areas set aside for nature away from the resort developments.

Binh Ba (Khanh Hoa) is a smaller island favored for fresh seafood—especially lobster—and quiet beaches. It lies within easy reach of Cam Ranh and Nha Trang and is a common short-stay destination for domestic visitors seeking calm water and local eateries.

Con Dao (Ba Ria–Vung Tau) is an archipelago of largely uninhabited islets with significant natural biodiversity and beach stretches. It is more remote and has only limited tourism infrastructure, which appeals to travelers who want fewer crowds and wildlife-focused visits. The islands also contain sites tied to the nation’s modern history.

Nam Du (Kien Giang) consists of many islets southwest of Phu Quoc and is often visited by backpackers and small-group tours. Several islands are inhabited and the group is best visited when the seas are calm. Regulations and local access requirements may vary, so confirm entry rules for international visitors in advance.

Phu Quoc (Kien Giang) is Vietnam’s largest island destination, offering over 150 km of coastline, a mix of beaches, forests and a national park on roughly half the island. It has the most extensive tourism services among the islands listed here, including an international airport and a wide range of accommodation options.

Practical tips for planning island visits

Access varies by island. Short excursions from mainland ports are common for islands near heritage towns, while more distant archipelagos require longer ferries or domestic flights. For example, several central islands are often reached by speedboat from nearby cities, while Phu Quoc and Con Dao have airport connections from major southern cities.

Timing matters: some islands are best visited in the dry season when seas are calmer and visibility for snorkeling is higher. For planning seasonal travel consider consulting a seasonal travel guide to align island choices with weather patterns. Ferry schedules and boat crossings can be disrupted during monsoon months, so allow flexibility in your itinerary.

• Book transport and accommodation in advance during public holidays.
• Check whether any entry permits or local restrictions apply—some islands have controlled access for security or conservation reasons.
• Bring reef-safe sunscreen and basic reef gear if you plan to snorkel, as rental options vary.

Cultural and environmental context

Island communities across Vietnam are frequently fishing-based, and many villages retain traditional livelihoods. Respect for local customs and signs—especially where military or conservation zones exist—is important. Where the island economy depends on seafood, menus often change with the catch and seasons.

Environmental sensitivity is also a consideration. Some islands contain protected marine parks or terrestrial reserves; visitors are encouraged to avoid stepping on reefs, to dispose of waste properly, and to support conservation-friendly operators if engaging in activities such as diving or island-hopping.

Who each island suits

Choose an island according to what you want from the trip. For minimal facilities and quiet beaches pick less developed islets such as Co To or Binh Ba; for short snorkel stops near cultural towns, Cu Lao Cham is convenient; Cat Ba offers a balance of outdoor activity and historical interest; Phu Quoc provides the broadest range of services and is easier for mixed itineraries.

For active travel—kayaking, hiking and scuba diving—some islands have established operators and more options. If you are assembling a multi-stop route across the coast, see suggested active options in our adventure activities piece to pair island days with land-based pursuits.

Comparisons and alternatives

When choosing between islands, consider travel time from your entry point, the level of tourist infrastructure you prefer, and the activities you want. Some travelers pick one well-serviced island and base there for day trips; others island-hop to experience contrasting landscapes.
