Kambodja

Home to diverse landscapes and peoples, eastern Cambodia shatters the illusion that the country is all paddy fields and sugar palms. There are plenty of those in the lowland provinces, but here they yield to the mountains of Mondulkiri and Ratanakiri Provinces, where ecotourism is playing a major role in the effort to save dwindling forests from the twin ravages of illegal logging and land concessions.

Sleepy Koh Kong (ក្រុងកោះកុង) was once Cambodia's Wild West with its isolated frontier economy dominated by smuggling and gambling. Although remnants of its less-salubrious past still cling on, today this low-slung town is striding towards respectability as ecotourists, aiming to explore the Cardamom Mountains and coastline, bring in alternative sources of revenue.

Gateway for the temples of Angkor, Siem Reap (see-em ree-ep; សៀមរាប) was always destined for great things. Visitors come here to see the temples, of course, but there is plenty to do in and around the city when you're templed out. Siem Reap has reinvented itself as the epicentre of chic Cambodia, with everything from backpacker party pads to hip hotels, world-class wining and dining across a range of cuisines, sumptuous spas, great shopping, local tours to suit both foodies and adventurers, and a creative cultural scene that includes Cambodia's leading contemporary circus.

Cambodia's southern islands are the tropical Shangri-La many travellers have been seeking – as yet untouched by the mega-resorts that have sprouted across southern Thailand. Many of the islands have been tagged for major development by well-connected foreign investors, but the big boys have been slow to press go, paving the way for DIY development to move in with rustic bungalow resorts.

Koh Rong (កោះរ៉ុង) was once little more than a jungle-clad wilderness rimmed by swaths of sugary-white sand, with a few beach-hut resorts speckling the shore around tiny Koh Tuch village. Today the Koh Tuch village street-strip that leads out from the pier is a bottleneck of back-to-back backpacker crash pads, restaurants and hole-in-the-wall bars blasting competing music. You'll either love it or hate it, but for young travellers who descend off the ferry in droves, Koh Rong (particularly Koh Tuch Beach) is a vital stop on any Southeast Asia party itinerary.

Cambodia's South Coast (ឆ្នេរខាងត្បូង) provides the antidote to temple-hopping tick lists. The beaches draw most folk here, but stick around and you'll see this region is more than its sandy bits.

Mondulkiri Province (ខេត្តមណ្ឌលគិរី), the original wild east, is a world apart from the lowlands with not a rice paddy or palm tree in sight.

The provincial capital of Mondulkiri, Sen Monorom (សែនមនោរម្យ) is really an overgrown village, a charming community set in the spot where the hills that give the province its name meet. In the center of town are two lakes, leading some dreamers to call it "the Switzerland of Cambodia."

Welcome to heaven on earth. Angkor (ប្រាសាទអង្គរ) is the earthly representation of Mt Meru, the Mt Olympus of the Hindu faith and the abode of ancient gods. The temples are the perfect fusion of creative ambition and spiritual devotion. The Cambodian ‘god-kings’ of old each strove to better their ancestors in size, scale and symmetry, culminating in the world’s largest religious building, Angkor Wat.

There's something about Battambang (បាត់ដំបង) that visitors just love. With its riverside setting and laid-back cafes, it's the perfect blend of relatively urban modernity and small-town friendliness.
