Siem Reap was once a home base for exploration of the Angkor Archaeological Park. But in recent years, it has become so much more than that. While exploration of the more than 400-square-kilometre park, which includes the remains of the ancient Khmer Empire, is undeniably a must-see for a portion of your 48 hours in the city, it's not all you should do. Siem Reap has blossomed into so much more than the "Gateway to Angkor Wat," and this is how you can fill 48 hours with adventure, delicious eats, nightlife and even a little Cambodian-style relaxation.
