Laos

From its sleepy tuk-tuk drivers to its location on the right bank of the lumbering, lazy Mekong, this former French trading post is languid to say the least. Indeed, despite being the capital and largest city of the Lao People's Democratic Republic, there's not a whole lot to do in Vientiane (ວຽງຈັນ). But that is also, quite honestly, its selling point.

Languid, time-trapped and somnolent during the sweltering days that batter the old city's plasterwork, Savannakhet (ສະຫວັນນະເຂດ) is a charming blend of past and present Laos. The highlight is the historic quarter with its impressive display of decaying early-20th-century architecture. There's little to do in town but wander the riverfront and cool off in one of a clutch of stylish restaurants and bijou cafes that are steadily growing in number.

Whether it's for trekking, cycling, kayaking, ziplining or a family homestay, a visit to northern Laos is for many the highlight of their trip. Dotted about are unfettered, dense forests home to big cats, gibbons and a cornucopia of animals, with a well-established ecotourism infrastructure to take you into their heart.

Southern Laos is dominated by the Bolaven Plateau, a fertile highland that spreads over four of the region’s provinces. It is the site of Laos’ thriving coffee plantations and also many of the region’s beautiful waterfalls.

Ever since Tha Khaek opened its French-colonial shutters to travelers and the dramatic 4.3 mile-long underworld of Tham Kong Lor became a must-see fixture on itineraries, central Laos has been enticing visitors. Thanks to its honeycomb of caves and dragon-green jungle, activities on offer run from world-class rock climbing outside of Tha Khaek to trekking in the otherworldly karst forests of Hin Namno NPA.

The vast majority of travellers to Si Phan Don end up on these twin islands. Don Det (ດອນເດດ) is defined by its hippyesque party scene, though it's really quite mild and there's nothing stronger than grass in the 'happy' snacks sold openly at some bars.

Spreading across parts of all four southern provinces, the fertile Bolaven Plateau (ພູພຽງບໍລະເວນ; known in Lao as Phu Phieng Bolaven) is famous for its cool climate, dramatic waterfalls and high-grade coffee.

Luang Prabang (ຫລວງພະບາງ) slows your pulse and awakens your imagination with its combination of world-class comfort and spiritual nourishment. Sitting at the sacred confluence of the Mekong River and the Nam Khan (Khan River), nowhere else can lay claim to this Unesco-protected gem's romance of 33 gilded wats, saffron-clad monks, faded Indochinese villas and exquisite fusion cuisine.

Hin Namno NPA might just be one of the most stunning protected areas in Laos, if not in all of mainland Southeast Asia, and the experts seem to agree: combined with two linked protected zones in neighbouring Vietnam, the greater area – the largest karst region in the world – is, at the time of writing, under consideration as a bi-country Unesco Natural World Heritage site.

Si Phan Don (ສີ່ພັນດອນ) is where Laos becomes the land of the lotus-eaters, an archipelago of islands where the pendulum of time swings slowly and postcard-worthy views are the rule rather than the exception. Many a traveller has washed ashore here, succumbed to its charms and stayed longer than expected.
