Mekong Adventure | South Laos Tour

A fascinating journey overland and down river, following the Mekong through southern Laos into northern Cambodia

Off-the-beaten-track Laos tour

A 2-week Central and South Laos tour following the mighty Mekong by boat and by road from the riverside capital Vientiane through rarely-visited parts of central and southern Laos to remote cliff-top Preah Vihear and the town of Siem Reap in northwestern Cambodia.

The lesser-known central and southern parts of the country hide some of Lao’s – and indeed Southeast Asia’s – most sublime scenery including the awe-inspiring Tolkien-esque mountain karst scenery of Hin Boun – where we’ll travel up an underground river to visit a hidden valley – the plantations and waterfalls of the Boloven Plateau, bucolic landscapes of the 4,000 Islands and, last but not least, the majestic Khone Phapaeng Falls on the Lao/Cambodian border. (One of the world’s largest, yet least-known, waterfalls.)

The tour also includes the charming French-period river ports of Thakaek and Pakse as well as the UNESCO World Heritage sites of Wat Phu – a pre-Angkor Khmer temple spectacularly situated on a hillside overlooking the Mekong and Cambodia’s awe-inspiring Preah Vihear Temple, perched on the edge of a sheer 600-metre cliff!

Our South Laos tour actually finishes over the border in Cambodia’s Siem Reap so, for anyone with a few more days to spare, you can add on a 3rd World Heritage site and visit, (or even re-visit) the fabulous ruined jungle cities and vast temples of Angkor.

An unforgettable journey by land and river through some of the most spectacular, but little-known, scenery that Southeast Asia has to offer.

Also, note that for those with a bit more time on their hands an extended version of this tour includes 2 more of Lao’s UNESCO World Heritage sites. Beginning in the ancient mountain capital of Luang Prabang the extended trip takes you across the mountains of northeastern Laos to the enigmatic, and also recently UNESCO-listed site known as the Plain of Jars.

Since airfares are fluctuating wildly at present, as well as varying considerably from period to period, our ‘with flight’ prices, below, are approximate only.



Here's an idea of what you can expect to do and see day-to-day.

Visa Info & Notes

Laos: visas are available on arrival at Luang Prabang International Airport for between $30 & $42 depending upon nationality

Cambodia: 30-day tourist visas are issued at the visa on arrival counters at international airports as well as any land entry point. For some reason, Swiss, Luxembourgeois and Russian passport holders are exempt from visas while any nationalities not included in the visa on arrival list will need to apply at a Lao embassy or consulate beforehand.

The fees are only payable in $US except for Thai/Lao land crossings where baht are accepted and this is where things do get slightly complicated as pricing does vary from country to country. Most European passport holders plus South African, Australian and NZ are charged $30 with the exception of Swedish who pay $1 more and British who pay an extra $5.  US citizens are also charged $35 while, for reasons we can’t fathom, Canadians pay $41. (Note a $1 overtime fee is charged for public holidays and outside of standard Lao office hours.)

Both: Requirements are at least 6 months passport validity, a minimum of 1 blank page and 2 passport-sized photos. Both tourist visas are 1-page stick on type and you’ll receive additional, regular-sized,  entry and exit stamps.

Tipping: we recommend a kitty system for the smaller, daily tips such as hotel/restaurant staff and local guides and drivers. Amounts inevitably vary with group size but would generally be in the region of $3-4 per person, per day. With regards guides accompanying you for longer periods we’d recommend a separate tip of approximately $5 per person, per day though of course, this is always discretionary and performance-related. (Local currency or USD are fine.) 

Meals: Breakfasts are generally hotel buffets with lunch and dinners based on local food. Your tour leader will usually order a selection of dishes, local-style, while a number of meals are not included, which allows you to ‘do your own thing’ or take a break if you’re feeling ‘riced out’.

Although you may assume Lao cuisine is little-known outside of Laos the fact that it’s hugely popular in neighbouring Thailand is a good reference and indeed many well-known Thai dishes such as the famous green papaya salad (som tam) and spicy minced pork salad (laap) are of Lao origin. Certain dishes then can be pretty firey – though your tour-leader can, of course, ask for them to be toned down – while the more Chinese and Vietnamese influenced dishes, which will be more familiar to foreign travellers, being generally mild.

Both vegan and vegetarian diets are easily catered to.

Accommodation: all choices fall into the comfortable 3* range and are en-suite and air-conditioned. We have posted a selection of sample accommodation on the lefthand hotel tab but please note that as we try and avoid the larger hotels, availability, in high season particularly, means we use several options in each destination.

Activities: note that no activities are compulsory and that any offered, including trekking, can be tailored for any fitness level or alternatives suggested.
