This Unesco-protected gem, which sits at the sacred confluence of the Mekong River and the Nam Khan (Khan River), has rightfully gained mythical status as a travellers’ Shangri La, and since its airport opened a decade ago the town has seen a flood of investment, with once-leprous French villas being revived as fabulous – though affordable – boutique hotels.

Beyond the evident history and heritage of the old town are aquamarine waterfalls, top trekking opportunities, meandering mountain bike trails, elephant camps, kayaking trips, river cruises and outstanding natural beauty, the whole ensemble encircled by hazy green mountains.
