Kambodja

You can really get away from it all at this lush, elevated park a two-hour drive southwest of Phnom Penh. Winding trails lead through pine forests to cascading wet-season waterfalls and cliffs with amazing views of the Cardamom Mountains, and there’s some great mountain biking to be done if you’re feeling adventurous.

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.

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.

The traveller's first glimpse of Angkor Wat, the ultimate expression of Khmer genius, is matched by only a few select spots on earth. Built by Suryavarman II (r 1112–52) and surrounded by a vast moat, the temple is one of the most inspired monuments ever conceived by the human mind.

A supremely mellow riverside town, Kratie (ក្រចេះ, pronounced kra-cheh) has an expansive riverfront and some of the best Mekong sunsets in Cambodia. It is the most popular place in the country to see Irrawaddy dolphins, which live in the Mekong River in ever-diminishing numbers. There is French-era architecture here, as it was spared the wartime bombing that destroyed so many other provincial centers.

Looking for temples without the tourist hordes? The remote temples of Northwestern Cambodia are a world apart. While hilltop Prasat Preah Vihear is the big hitter, the other temple complexes – wrapped in vines and half-swallowed by jungle – are all fabulous to wander.

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.

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.

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.

Sure, Sihanoukville (ក្រុងព្រះសីហនុ) would never win first prize in a pretty-town competition, and much of it is now dominated by casinos and tacky commercial centres. But despite the rapid and mostly unwanted development, it has remained the jumping-off point for the best of Cambodia's white-sand beaches and castaway-cool southern islands. The Serendipity Beach area is a decompression chamber for backpackers, who flock here to rest up between travels and party through the night.
