Laos

Mysterious giant stone jars of unknown ancient origin are scattered over hundreds of hilly square kilometres around Phonsavan, giving the area the misleading name of Plain of Jars (ທົ່ງໄຫຫິນ). Remarkably, little is known about the Austro-Asiatic civilisation that created them, although archaeologists estimate they date from the Southeast Asian iron age (500 BC to AD 200) and were likely used for elaborate burial rituals.

Like a rural scene from an old Asian silk painting, Vang Vieng (ວັງວຽງ) crouches low over the Nam Song (Song River) with a backdrop of serene cliffs and a tapestry of vivid green paddy fields. Thanks to the Lao government closing the river rave bars in 2012, the former party scene has been driven to the fringes and the community is rebooting itself as an adrenaline-fuelled adventure destination.

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.

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.

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.

Pakse (ປາກເຊ), the capital of Champasak Province and the gateway to southern Laos, sits at the confluence of the Mekong and the Se Don (Don River). It's a relatively lively town with lots of accommodation and eating options, as well as transport connections, and many travelers base themselves here for forays to surrounding attractions such as the Bolaven Plateau and Wat Phu Champasak. The many good restaurants, stylish hotels and clued-in tour companies make it a comfortable and convenient spot.

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.

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.

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.

Phu Hin Bun NPA (ປ່າສະຫງວນແຫ່ງຊາດພູຫີນປູນ) is a huge (1580 sq km) wilderness area of turquoise streams, monsoon forests and striking karst topography across central Khammuan. It was made a protected area in 1993 and it's no overstatement to say this is some of the most breathtaking country in the region. Exploring the NPA on foot or by boat, it's hard not to feel awestruck by the very scale of the limestone cliffs that rise almost vertically for hundreds of metres into the sky. Arguably the highlight of the NPA is Tham Kong Lor, a 7.5km river passing through the cathedral-high limestone cave.
