Kambodja

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."

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.

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.

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.

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.

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.

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.

Founded as a seaside retreat by French colonizers in 1908 and a favoured haunt of Cambodian high-rollers during the 1960s, sleepy Kep (កែប, Krong Kep, also spelled Kaeb) is drawing tourists back with seafood, sunsets and hikes in butterfly-filled Kep National Park. Its impressive range of boutique hotels squarely targets a more cultured beach crowd than the party-happy guesthouses of Sihanoukville and the islands.

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.

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.
