Laos

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.

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.

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.

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.

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.

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.

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.

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.

Nong Khiaw (ຫນອງຂຽວ) is a traveler's haven in the truest sense, offering pampering, good food, decent accommodation and bags of activities with established adventure-tour operators. Nestled on the west bank of the Nam Ou (the river almost currentless since the building of the dam upstream), spanned by a vertiginous bridge and bookended by towering limestone crags, it's surely one of the most photogenic spots in Laos. On the river's scenic east bank (officially called Ban Sop Houn) is the lion's share of guesthouses and restaurants.

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.
