Cambodia's capital Phnom Penh is a city that never stops - chaotic yet wonderfully charismatic - as it sits on the banks of the mighty Mekong River, which flows from the mountains of Laos through the length of Cambodia and empties into the sea via a delta in southern Vietnam.
Phnom Penh has beautiful temples, palaces and pavilions, stunning dining and shopping, a vibrant nightlife and some dark historical stories: such as Toul Sleng - the notorious genocide prison and Choeung Ek - the extermination camp known as "The Killing Fields".
Siem Reap is the city next to the enormous Tonlé Sap Lake which is the largest freshwater lake in southeast Asia and permanent home to more than 90 000 people who live in around seventy floating villages on the lake. This is along with huge numbers of permanent and migratory birds who also make the lake their home.
Siem Reap is also the town outside which you find the remarkable Angkor temple complex. This mind-blowing complex remembers another time when the Khmer empire ruled much of what is now known as Cambodia, Thailand, Laos and Vietnam - between 800 and 1400 AD.
Siem Reap is also where you can indulge in numerous different types of adventure tourism. These include zip-lining, quad biking, cycling, hiking, trekking as well as food tours, cooking, bird-watching and playing golf at a number of great courses. The old city of Seam Reap has wonderful examples of French colonial architecture, a night market, a festive pub scene, excellent restaurants as well as a great craft brewpub.
