Laos – The Secret Heart of Asia

A unique tour to South East Asia’s best kept secret, Laos, where we get well beyond the tourist trail. We start this cultural odyssey in Vientiane, Laos’ delightfully friendly capital, studded with crumbling French mansions, bougainvillea­-blooming streets and steaming noodle stalls. Next up is the little visited North of Laos to experience the ethnic diversity of the many hill tribes in the region of Luang Namtha and observe local customs and traditions. A 2-day journey down the mighty Mekong River then awaits culminating in an arrival in Luang Prabang, which captivates even the most jaded travellers with its brew of gleaming temple roofs, crumbling French provincial architecture and multi-ethnic inhabitants. Nest we head south to the spectacular lush jungle of the Bolaven Plateau and immerse ourselves in authentic coffee culture and visit some of the most alluring scenery in Asia, the landscape scattered with volcanos and sparkling waterfalls. The conclusion of this off the beaten track adventure takes us to the enchanting 4000 islands, an area where time stands still, and revel in the joy of leisurely exploring villages by bicycle or tuk tuk and even try your hand at fishing. Join us to experience the hidden charms of Laos.

What to do

Key experiences at 4000 Islands Laos (Si Phan Don)

  • Cycle through the rice fields of Don Khone

    Cycle through the rice fields of Don Khone

    Hire a bicycle and follow the flat paths that wind between paddies, wooden village houses, and riverside viewpoints. The island is compact enough to cover at a gentle pace, with frequent opportunities to stop and watch daily life unfold without any tourist rush.

  • Join a local fisherman on the Mekong

    Join a local fisherman on the Mekong

    Board a traditional wooden boat with one of the island's fishermen and head out to the fishing grounds. You can try throwing nets yourself, and as the light fades the group gathers at a secluded riverside spot for a BBQ while a guide recounts local myths of the river.

  • Kon Phapheng Waterfall

    Stand at Kon Phapheng Waterfall

    The entire volume of the Mekong crashes down at Kon Phapheng, the largest waterfall by volume in Asia. The force of the water is genuinely arresting, and the viewpoints allow you to take in the full width of the falls before continuing north towards Pakse.

  •  tuk tuk at island pace

    Explore by tuk tuk at island pace

    For those who prefer not to cycle, tuk tuks weave the same routes between villages and let you cover more ground while still stopping whenever something catches your eye. It is a practical and characterful way to take in the southern islands.

  • Mekong at dusk from Don Khone

    Watch the Mekong at dusk from Don Khone

    As the sun drops behind the river, the light across the water changes quickly. It is a truly idyllic scene, and as dusk settles, you will gather at a secluded spot to enjoy a delicious BBQ and listen to local river myths shared by your guide—an evening most travellers remember long after leaving Laos.

About this place

The story behind 4000 Islands Laos (Si Phan Don)

4000 Islands Laos

The 4000 Islands Laos — known locally as Si Phan Don — sit in the far south of the country where the Mekong River fans out across a width of 14km, scattering hundreds of sandy islands between its channels. The name is an approximation: at the height of the wet season the count rises, in the dry season it falls. What stays constant is the atmosphere: roosters, rice paddies, wooden boats, and a tranquil pace of life that feels entirely removed from the modern world.

Don Khone and the Islands

The most visited of the islands is Don Khone, which serves as the peaceful base for our travellers. Characterised by wooden stilt villages, river-facing guesthouses, and a distinctly laid-back charm, it is the perfect place to immerse yourself in the peaceful atmosphere of the archipelago. The islands see far fewer visitors than the north of the country, offering a genuine glimpse of rural Lao life largely unchanged for generations.

Kon Phapheng Waterfall

Located just north of the Cambodian border, the Kon Phapheng Waterfall is the largest waterfall by volume in Asia — the entire Mekong River descends here in a thunderous curtain of white water, making for a truly amazing spectacle. It is visited as a short stop en route from the 4000 Islands to Pakse, forming a natural full stop to any visit to the south of Laos.

Visiting with Undiscovered Destinations

Our guided group tours in Laos include the 4000 Islands as the final chapter of a longer journey through southern Laos, arriving after the Bolaven Plateau for a relaxing two-night stay on Don Khone Island. After an initial afternoon at leisure to relax by the pool and immerse in the peaceful atmosphere, the following day is dedicated to exploring the islands and experiencing the slower pace of life along the Mekong.

In the morning, guests have the choice of gentle cycling past the rice fields and friendly villages of the island, or exploring by tuk tuk. In the afternoon, a local fisherman takes the group out on a traditional wooden boat to the fishing grounds, where you can try your luck at throwing nets into the water. At dusk, the evening ends with a delicious BBQ at a secluded spot while a guide shares local myths of the Mekong. The route then continues north to Pakse, stopping at the magnificent Kon Phapheng Waterfall along the way.

The 4000 Islands feature on both our Laos – The Secret Heart of Asia and Laos and Cambodia Encompassed itineraries, both operated with a maximum of 12 travellers for a more immersive small group experience.
