What to do and see on the 4,000 islands?
At the 4,000 islands, there's no stress—the atmosphere is laid-back, and activities lean toward nature to make the most of the stunning landscapes. On the agenda: walks on foot or by bike through rice paddies and the islands' authentic villages, giving you a chance for unique encounters with locals and to immerse yourself in daily life here, shaped by fishing, weaving, and agriculture.
A few kayaking or canoeing excursions, as well as tubing (on a large inflatable ring), are also available on the Mekong. Swimming is possible but not always recommended due to currents and waterfalls that may exist in certain areas.
It's from the 4,000 islands that you can take a long-tail boat to try and spot the pink river dolphins of the Irrawaddy, an endemic species on the brink of extinction due to fishing. With a bit of luck, you may catch sight of a few.
The archipelago has many islands, but three particularly stand out: Don Det, Don Khong, and Don Khone.
Don Det, the Lively One
Don Det, located to the south of the archipelago, is the archipelago's smallest island at just 4 km long but perhaps its most popular, known for its vibrant reputation. Famous among young backpackers as a party haven, the island has gradually become more laid-back over time. The vibe is rather pleasantly chill with its handful of waterside bars and small guesthouses. Of course, you can party here, but the place remains very calm and agreeable. Restaurant and hotel options abound—you'll easily find a cozy bungalow on the Mekong's banks.
Here you can rent a kayak to venture into the river's waters and discover the beauty of the 4,000 islands. You can also explore the island by bike and reach Don Khong, accessible via the bridge connecting the two islands. For those seeking an original water activity, tubing is also offered. At day's end, relax on a terrace or in the hammock on your balcony and enjoy the magnificent sunset that illuminates the island in orange hues every evening.
Don Khong, the Restful One
Don Khong is the largest of the islands at 18 km long and 8 km wide, yet probably the least touristy of the three. Here you unwind, wander, observe, and stroll—the atmosphere is easygoing and deeply pleasant; you quickly settle into this leisurely rhythm.
It's possible to rent a bike to circle the island; pleasant walks will take you through the heart of rice paddies and past small authentic villages where little temples hide waiting to be discovered. Stop by the vegetable market and the small port to watch fishermen unload their morning catch, and finish the day at the beach to relax.
Don Khone, the Family-Friendly One
As mentioned earlier, Don Khone (or Don Khon) island is linked to Don Det by a French bridge spanning about fifty meters. Renowned for its calm, family-friendly atmosphere, you'll find pleasant walks along the railway lines, traces of French colonization. This former colonial territory is also marked by a few remnants, including an abandoned small schoolhouse and an old locomotive now on display.
During your stay on Don Khone, you'll be able to admire the splendid Phapheng Falls, considered Southeast Asia's largest waterfalls. Further on, discover the Li Phi Falls as well, said to be inhabited by spirits.
The island is also renowned for its bamboo, coconut, and kapok (a plant fiber derived from the fruits of several trees) cultivation.
Like the others, the island isn't particularly large (5 km long by 3 km wide) and is easily explored on foot or by bike. Boat excursions to see the dolphins typically depart from this island.
How to reach the 4,000 islands?
The archipelago is accessible from two locations: the city of Paksé and Cambodia.
From Paksé, minibuses depart daily toward the embarcadero at Nakasong. From there, boats take you to the islands.
From Cambodia, which shares a border about fifteen kilometers away, it's easy to reach the Nakasong embarcadero and then the islands.
