The Emerald Triangle

An exploration of the rarely-visited 'Emerald Triangle' where Thailand, Laos and Cambodia meet. Visit the spectacular 4,000 Islands of the Mekong River and World Heritage Wat Phu and Preah Vihear

Off-the-beaten-track Thailand, Laos and Cambodia tour

Our 2-week Thailand, Laos and Cambodia tour – ‘The Emerald Triangle’ – explores the picturesque yet rarely-visited region in the heart of Indochina where the borders of the three countries meet.

Journey by train from the capital Bangkok to the northeastern region of Thailand, known as I-san, where we’ll visit the fabulous Angkor-period temples of Phnom Rung atop an extinct volcano and charming Muang Tham surrounded by lily ponds.

From here, we’ll continue, via the picturesque Mekong-side town of Khong Jiam and spectacular Pha Taem National Park, into southern Laos. Discover the Boloven Plateau and World Heritage Wat Phu, before heading south to the stunning ‘Four Thousand Islands’, where the Mekong cascades into Cambodia over a series of stunning falls. (Some of the world’s largest, yet least known.)

After a boat journey, down what to our minds is the most scenic stretch of the Mekong, into northern Cambodia, we’ll head west to the awe-inspiring site of Preah Vihear – now also UNESCO World Heritage protected – where an 11th-century temple emerges from sheer 600-metre cliffs to overlook the forests of the northern Cambodian plain. After a sunrise visit, a morning’s drive takes us to our final destination Siem Reap with a day at leisure before departure from its international airport.

An unforgettable journey through a little-known but fascinating region of Southeast Asia.

Note that, for those with a few more days to spare, you can extend your tour to discover, or re-visit, the fabulous jungle temples of Angkor.

Visa Info & Notes

Visas – Thailand: No visa in advance is required. A free 30-day visa for Thailand is issued on arrival at an international airport.

Visas – Laos: No visa in advance is required. A 30-day visa can be obtained for you at the border. Approx. $38).

Visas – Cambodia: For most nationalities, a visa on arrival is issued at the borders though please do check beforehand. Visa fees and conditions are subject to change but are usually $30 payable in cash in US dollars.

All: A passport photo is required for both Laos and Cambodia while tourist visas for both are valid for 30 days from entry.

Your passport should be valid for a minimum period of 6 months from the date of entry and you may be refused entry if your passport is damaged, in poor condition or does not have at least 2 blank pages remaining.

Meals: breakfasts are generally hotel buffets with lunch and dinners based on local food. Lunches on the road are typically simpler dishes such as variations on noodles or fried rice while your tour-leader will generally order more elaborate-style dinners consisting of a selection of local fare. The cuisine shows both Thai and Vietnamese influences though with plenty of unique dishes too.

Thai cuisine needs no introduction while much lesser known Lao fare is somewhat similar though commonly accompanied by ‘sticky’, rather than plain rice. Dishes in both countries can be spicy so please indicate your chilli tolerance levels to your tour leader. Both vegetarians and vegans are very easily catered for. For any other likes and dislikes please remind your tour-leader at the start of the tour.  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’.

Accommodation: all choices fall into the comfortable 3* range and are en-suite and air-conditioned with, where possible, pools. 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 can be tailored for various fitness levels or alternatives suggested.
