4,000 Islands (Si Phan Don): A Must-Visit Stop on Any Southern Laos Motorbike Journey

The 4,000 Islands (Si Phan Don) form one of the most peaceful and atmospheric corners of Laos. Located in the far south of the country, right on the Cambodian border, this river archipelago offers a blend of tranquil Mekong scenery, impressive waterfalls, and a laid-back island lifestyle that feels frozen in time.

For motorbike riders – especially those on the Bolavean/Pakse Loop – Si Phan Don is an essential stop before continuing north or crossing into Cambodia.

The two most visited islands, Don Det and Don Khon, are known for bamboo bungalows, hammock-filled riverside cafés, and now sealed paths that wind through rice fields and fishing villages. Life here moves slowly, and that’s exactly the appeal.

While most visitors head to Don Det and Don Khon, the wider archipelago also includes Don Khong, Don Som, and Don Nangloy – each offering its own charm, landscapes, and level of tranquility.

The Main Islands of Si Phan Don

Don Det – The Lively Backpacker Hub

Don Det is the island most travellers start with. Known for:

• Riverside bungalows overlooking the Mekong

• A vibrant backpacker atmosphere on the northern tip

• Quiet rice fields and villages on the south side

• Excellent sunrise and sunset viewpoints

Motorbikes make it easy to escape the busier guesthouse areas and explore the quieter tracks around the island.

Don Khon – Waterfalls, History & Relaxed Village Culture

Connected to Don Det by the historic French railway bridge, Don Khon offers:

• Li Phi (Somphamit) Waterfall, wide and powerful, especially in rainy season

• The old French ports once used to bypass the impassable rapids

• Shaded, peaceful roads winding past fishing villages

• The Mekong zipline, offering thrilling views above the rapids

Don Khon is ideal for travellers wanting quiet natural beauty and historical landmarks without the party scene.

Don Som – Quiet Villages & Authentic Mekong Life

Don Som is perfect for those seeking a slow, culturally immersive island experience.

Why visit:

• Minimal tourism compared to Don Det/Don Khon

• Dirt tracks running the length of the island

• Stilt houses, fishing villages, and traditional daily life

• A handful of warm, welcoming homestays

Riding across Don Som feels like stepping into the untouched Mekong of decades past.

Don Khong – The Largest Island, Ideal for Riders

As the biggest island in Si Phan Don, Don Khong offers:

• Long, easy roads suitable for full-day motorbike exploration

• Spacious landscapes and wide river views

• Local markets and temples

• A very relaxed, family-friendly atmosphere

Its size and convenience make Don Khong the best island for riders wanting an extremely calm base with more infrastructure. Recently Don Khong was named Southeast Asia’s top island for cycling by National Geographic – https://www.nationalgeographic.com/travel/article/which-is-the-best-island-in-southeast-asia-for-you

Don Nangloy (Done Nang Loy) – Untouched, Serene & Deeply Local

Don Nangloy is one of the most overlooked and tranquil islands in the entire 4,000 Islands region.

What makes Don Nangloy special:

• Even fewer visitors than Don Som

• A peaceful community where traditional Mekong life continues unchanged

• Dirt tracks passing through rice paddies, banana groves, and scenic riverbanks

• Authentic home-cooked meals and genuine village hospitality

• Superb for riders who want a slow, reflective escape far from tourism

Getting to 4,000 Islands with a Motorbike

Most riders travel south from Pakse, about 150 km away.

Best Route: Highway 13

• Smooth, reliable sealed road

• Follows the east bank of the Mekong

• Straightforward navigation

• Two ferries required to reach Don Det/Don Khon

Avoid the West Bank Route

Although the road is good near Champasak, it soon becomes rough dirt and is not suitable for reaching the islands quickly.

Motorbikes on the Islands

Cars are rare on Don Det, Don Khon, and Don Som.
Motorbikes are allowed and extremely useful – especially for reaching:

• The waterfalls

• Old port ruins

• Remote villages

• Don Som

• Don Nangloy

Kayaking

One of the most popular activities in Si Phan Don is kayaking, thanks to the slow, branching channels of the Mekong surrounding the islands.

You can:

• Rent a kayak and explore at your own pace

• Join a full-day guided tour, which safely navigates calm areas and avoids faster, dangerous currents

Guided tours often include stops at waterfalls, swimming spots, and peaceful sandy riverbanks – ideal for photography.

Old French Port & Railway

Si Phan Don has a fascinating slice of colonial history. Because the Mekong’s waterfalls made boat travel impossible, the French constructed:

• Two ports – one on Don Det, one on Don Khon

• A railway to move boats and cargo across the islands

• A bridge linking Don Det and Don Khon, which still exists today

Although the ports are now only foundations and ruins, the motorbike ride to the south port is scenic and peaceful, passing through quiet rural areas and small villages.

Li Phi Waterfall & Mekong Zipline

Located on the western side of Don Khon, Li Phi Waterfall is one of the most dramatic natural sights in southern Laos. Instead of one big drop, the water crashes through a maze of rock formations, creating thunderous rapids.

During the rainy season, Li Phi becomes even more powerful – truly a sight to behold.

Visitors can:

• Walk across wooden bridges and platforms overlooking the falls

• Take the zipline, which flies high above the roaring water for a thrilling experience

Khone Phapheng Waterfall

Just south of the islands lies the incredible Khone Phapheng Waterfall, the widest waterfall in the world and the largest by volume in Southeast Asia.

This waterfall is massive – not tall, but extremely wide, with enormous amounts of water surging through multiple channels.

Facilities include:

• Viewing platforms

• Easy, well-maintained access

Since Khone Phapheng is only reachable from the mainland, most riders stop here:

• On the way to the islands, or

• When returning before heading north toward Pakse

It’s only 12 km from Nakasong ferry port, making it a convenient addition to your route.

Relaxing in a Hammock

For many travelers, the true attraction of Si Phan Don is the chance to slow down. Life here moves at a different pace – sunset beers, riverside bungalows, and endless hammocks.

One of the best things to do on the 4000 Islands is simply nothing at all.
Watch the river drift by, enjoy the breeze, and experience the peaceful charm that makes visitors stay longer than planned.
