Top Things to Do in Siem Reap in January

Recommendation Rate of Travel:

In January, the most important thing to do in Siem Reap must be visiting the magnificent Angkor temple complex, the planet’s largest religious monument. However, before visiting the temple complex, it is advised to stop by the Angkor National Museum first. The museum displays some treasures of Angkor Wat, and tells the historical background, civilization, art, science and other knowledge of the giant complex, to lay the foundation for your Angkor Wat tour. Then spend at least 2-3 days exploring the mysterious ruins of sprawling Khmer Empire. Among them, the Angkor Wat Temple, Bayon Temple, Banteay Srei, and Ta Prohm are unmissable highlights. Apart from majestic temple ruins, take a stroll around the Angkor Night Market where you can find most kinds of handicrafts and hand-carved jewelry. The pub street is also a great place for you to experience the vibrant nightlife.  


1. As January is one of the peak months of the year in Siem Reap, it is suggested to book hotels and tickets as early as possible. The prices of accommodation and flight may soar up.  
2. Though it is mild this month, the sunlight could be strong at noon and protecting your skin from sunshine is very necessary.
