Vietnam Island Hopping Guide: Best Islands, Routes and How to Plan Your Trip

Vietnam island hopping is one of travel’s great underrated pleasures. While most visitors know Phu Quoc, and many have heard of Ha Long Bay, Vietnam’s coastline conceals dozens of islands strung across thousands of kilometres of South China Sea — from the far north where limestone karsts rise from jade water, to the deep south where white sand meets gin-clear ocean and sea turtles nest undisturbed. No single island tells the full story. But island-hop across a handful of them, and Vietnam reveals itself as one of the finest island destinations on earth.

Why Vietnam Is Perfect for Island Hopping

Vietnam has an extraordinary geography for island hopping. The country’s coastline stretches more than 3,200km — longer than the eastern seaboard of the United States — dotted with over 3,000 islands of every size, character and ambience. There are party islands and hermit islands, dive destinations and surf breaks, fishing villages unchanged in a century and luxury resorts carved into forested hillsides. Many are connected by regular ferry services or cheap domestic flights; others require a private boat charter and a spirit of adventure.

The best time for island hopping in Vietnam depends heavily on which part of the country you are visiting. Vietnam’s complex weather patterns mean that when one coast is battered by rain, another is basking in sunshine. The south (Phu Quoc, Con Dao) is best from November to April, when the northeast monsoon keeps the sky clear and the sea calm. The central coast islands (Cham Islands, Ly Son) are best from April to August. The north (Ha Long Bay, Cat Ba, Lan Ha Bay) can be visited year-round, though April to June offers the finest combination of calm seas and clear skies. This seasonal variation means that a well-planned Vietnam island hopping route can actually extend your window of good weather by moving between regions.

Vietnam is also refreshingly affordable for island travel. Ferry crossings between major islands rarely cost more than $10 USD; budget guesthouses on most islands are available from $15–25 per night; and a freshly grilled seafood dinner on the beach — the default island dining experience — costs a fraction of what you’d pay in Thailand or Indonesia. Island hopping in Vietnam rewards both the budget backpacker and the traveller seeking well-designed luxury.

The Best Islands in Vietnam for Island Hopping

Vietnam’s islands divide naturally into clusters by region. Here are the finest candidates for your island hopping itinerary, from north to south.

Cat Ba Island (Ha Long Bay, north Vietnam) is the largest island in the Ha Long Bay archipelago and one of the most versatile. It functions as a base for exploring both Ha Long Bay and Lan Ha Bay — a less-visited southern extension of Ha Long’s karst landscape that many visitors prefer for its quieter atmosphere and clearer water. Cat Ba has proper trails, a national park with rare golden-headed langurs, kayak rentals and a small but genuinely excellent rock-climbing scene. Stay in Cat Ba Town for a night or two, take a day cruise into Lan Ha Bay, and you have the essence of northern Vietnam’s island character. Our full Cat Ba Island guide covers everything you need to plan the visit.

The Cham Islands (Cù Lao Chàm, central Vietnam) sit 15km off the coast of Hội An, reachable by speedboat in about 20 minutes. Eight small islands make up the archipelago, six of which are accessible to visitors. The marine park surrounding them — a UNESCO Biosphere Reserve — protects some of the most intact coral reef in central Vietnam; snorkelling and diving here reveal an underwater world of hard corals, reef fish, sea turtles and occasional whale sharks. The islands have a small permanent population of fishermen who maintain the same rhythms their ancestors kept. Stay overnight to experience the Chams at dawn and dusk, when the tour boats have gone and the village belongs to the islanders again.

Lý Sơn Island (Quảng Ngãi Province, central Vietnam) is one of Vietnam’s best-kept secrets. This small volcanic island — Vietnam’s garlic-growing capital, of all things — rises from the sea off the coast of Quảng Ngãi with a dramatic skyline of crater rims and lava flows. The snorkelling is excellent and largely undiscovered; the seafood, particularly the sea urchin, is extraordinary; and the island’s unique garlic-producing agricultural terraces are like nowhere else in Vietnam. Ferries run from Sa Kỳ port. Ly Son is a destination for those who want to go somewhere genuinely off the beaten track.

Phu Quoc Island (Gulf of Thailand, south Vietnam) is Vietnam’s largest island and its most developed tourist destination — but it retains significant stretches of unspoilt forest, deserted beaches and fishing village atmosphere if you know where to look. The northern tip of the island, protected within Phu Quoc National Park, is dense jungle; the southern coast has some of the longest uninterrupted beaches in Vietnam; and the western coastline catches extraordinary sunsets over the Gulf of Thailand. Phu Quoc also offers the best diving in the south of the country. Our full Phu Quoc travel guide covers the island in detail.

Con Dao Islands (Bà Rịa–Vũng Tàu Province, south Vietnam) are the greatest island secret in Southeast Asia. An archipelago of 16 islands 180km off the southern coast, Con Dao is so remote and so carefully protected that it has remained largely pristine while the rest of Vietnam developed. The national park that covers most of the land area is one of the finest in Asia: hawksbill sea turtles nest on the beaches in their hundreds from June to September; dugongs graze the sea grass beds; whale sharks pass through the offshore waters. The waters around Con Dao offer some of the best diving in Vietnam — visibility routinely exceeds 20 metres, and the coral is in extraordinary condition. Con Dao Town, the small capital, has a sober historical significance as the site of Vietnam’s most notorious colonial-era prison; a visit to the prison museum is a sobering and essential counterpoint to the island’s natural beauty.

Vietnam Island Hopping Routes by Region

The most practical way to plan a Vietnam island hopping trip is to choose a regional cluster and explore it thoroughly, rather than trying to cover the whole country. Here are three well-tested routes.

Route 1: The Northern Circuit (7–10 days) — Base yourself in Cat Ba Town and use it to explore both Ha Long Bay and Lan Ha Bay. Take a 2-night cruise through Ha Long Bay’s most dramatic karst landscapes, then spend two days kayaking the quieter channels of Lan Ha Bay. Day trips to the outlying islands of Cát Hải are possible by local ferry. From Cat Ba, a return to Hanoi allows onward connections to central Vietnam. This route is particularly good from April to June, before the summer rains arrive in the north.

Route 2: The Central Coast Circuit (5–7 days) — Use Đà Nẵng or Hội An as your hub. From Hội An, a 20-minute speedboat takes you to the Cham Islands for snorkelling and overnight stays. Return to Hội An after two nights, then take a bus or domestic flight to Quy Nhơn, from where ferries run to Phú Quy Island (another underrated volcanic island with good diving). Alternatively, travel south to Quảng Ngãi and ferry across to Lý Sơn. This route covers the most geographically varied section of Vietnam’s coastline and can be combined with a visit to Hội An or Da Nang on the same trip.

Route 3: The Southern Island Circuit (10–14 days) — This is the grandest Vietnam island hopping route, combining Phu Quoc and Con Dao in a loop from Ho Chi Minh City. Fly from Ho Chi Minh City to Con Dao (1 hour), spend 3–4 nights exploring the national park and diving the coral reefs, then fly to Phu Quoc (1 hour direct). Spend 4–5 nights on Phu Quoc exploring the northern forests, southern beaches and offshore dive sites, then fly back to Ho Chi Minh City. This circuit gives you two of the finest island experiences in Southeast Asia back to back — and because Con Dao and Phu Quoc have very different characters, one feels like a contrast to the other rather than a repetition.

Best Time to Go Island Hopping in Vietnam

Vietnam’s island weather is governed by two distinct monsoon patterns that affect different parts of the coastline at different times. The key principle is that you can almost always find good island weather somewhere in Vietnam — you just need to know where to go when.

The south (Phu Quoc, Con Dao) enjoys its dry season from November to April. Seas are calm, skies are clear, and visibility for diving is excellent. The wet season (May to October) brings rougher seas and frequent rain; some speedboat services to Con Dao are cancelled during this period. The turtle nesting season at Con Dao runs June to September — an extraordinary spectacle, but it coincides with the edge of the wet season, so plan accordingly.

The central coast (Cham Islands, Ly Son) is best from April to August, before the northeast monsoon arrives in September. Hội An’s old town floods during the October–November monsoon; Cham Island boat services may be suspended. April, May and June are ideal — dry, warm and uncrowded.

The north (Ha Long Bay, Cat Ba, Lan Ha Bay) can be visited year-round, though January and February are cool and sometimes misty. April to June is the finest window: warm, clear and before the summer tourist peak. September and October offer a secondary sweet spot as the summer crowds thin and the weather remains warm.

Getting Between Vietnam’s Islands: Ferries, Speedboats and Flights

Vietnam’s island transport network has improved dramatically in recent years, though it remains patchier than equivalent networks in Thailand or Indonesia. Here is what to expect by region.

North Vietnam islands: Regular ferries run between Hải Phòng and Cat Ba Island (1.5–2 hours, from 80,000 VND). Speedboats also run from Hạ Long City to Cat Ba. From Cat Ba, local boats take you further into Lan Ha Bay on day trips or multi-day charters.

Central Vietnam islands: Speedboats from Cửa Đại Beach near Hội An to the Cham Islands run multiple times daily in the dry season (20 minutes, around 250,000 VND each way). Ferries from Sa Kỳ port to Lý Sơn run daily (around 2.5 hours by ferry or 75 minutes by high-speed boat). Services can be suspended in rough weather.

South Vietnam islands: Phu Quoc has an international airport with direct connections to Ho Chi Minh City (1 hour), Hanoi, Da Nang and several regional destinations. Ferries from Hà Tiên and Rạch Giá on the mainland are also available. Con Dao is served by daily flights from Ho Chi Minh City (1 hour) and occasional flights from other cities; there are no regular ferry services from the mainland due to the distance and sea conditions. Vietnam Airlines, Bamboo Airways and Vietjet all serve the main island routes.

Practical Tips for Vietnam Island Hopping

A few pieces of practical wisdom will make your Vietnam island hopping trip significantly smoother. Cash is essential on smaller islands — ATMs are rare and card machines non-existent. Bring enough cash from the nearest mainland city to cover accommodation, food and transport for your stay. On Con Dao, the only ATM in town occasionally runs out of cash; carry extra.

Sunscreen, reef-safe where possible, is worth buying before you reach the islands — prices are higher on the islands themselves, and the selection is limited. A good mask and snorkel are worth bringing from home or renting in Hội An or Da Nang before heading to the Cham Islands. For diving, reputable operators on all the major islands provide full equipment rental.

Ferry schedules change seasonally and can be suspended without much notice in rough weather. Always book accommodation before arriving on smaller islands (Con Dao especially), as capacity is limited. If you are island-hopping on a fixed timeline, build buffer days into your itinerary — weather delays are common, particularly during the shoulder seasons.

Island hopping pairs naturally with Vietnam’s coastal city experiences. Starting from Ho Chi Minh City for the southern circuit, or from Hanoi for the northern circuit, gives you an urban base before and after the island adventure. If Vietnam’s islands are part of a longer trip, our 2-week Vietnam itinerary shows how to weave island time into a complete north-to-south journey. And if you want to pair the islands with beach and dive exploration, our guide to Vietnam’s hidden beaches reveals the best stretches of sand that most visitors never find.
