Top Things to Do in Siem Reap in August

Recommendation Rate of Travel:

Visiting Siem Reap in August, the first draw is still the world-famous Angkor Wat Temples. However, before going sightseeing in the giant Khmer Empire ruins, it is recommended to visit Angkor National Museum first, which collects many artifacts of the Angkor Wat Temple complex. Here you can not only learn about the Khmer culture but also know about the origins and backgrounds of the large temple complex. You’d better spend 1-3 days visiting the temple complex. You will be amazed at the sunset views at the hilltop temple of Phnom Bakheng. Banteay Kdei combining two different styles is also unmissable. August is also a perfect time to explore the Tonle Sap Lake and visit the floating villages. Also, take a stroll around the old market in Siem Reap to purchase some cheap and fine souvenirs.  


1. It is suggested to take a tuk-tuk or a car to travel among the masses of temples of the Angkor Wat. 
2. Always take an umbrella or a raincoat when exploring outside.
