Siem Reap FAQ

Is Siem Reap worth visiting?

Its primary draw is the magnificent Angkor archaeological complex, a UNESCO World Heritage site boasting hundreds of ancient temples that offer immense historical and cultural significance. Beyond the temples, Siem Reap provides excellent value for money with affordable food, drinks, and accommodation. You can also immerse yourself in local life through experiences like visiting floating villages on Tonle Sap Lake, enjoying performances at Phare the Cambodian Circus, or exploring bustling local markets.
What is the best month to visit Siem Reap?
The ideal time to visit Siem Reap is during the dry season, from November to April. While it remains warm, the temperatures are generally more pleasant than during the monsoon months. December to February typically offers the best weather conditions. By late April and May, the heat intensifies, and from May to October, it is the monsoon season.
What should I be cautious of in Siem Reap?
When in Siem Reap, it is advisable to be aware of your surroundings, especially in crowded temples and markets, to avoid pickpocketing. Utilize hotel safes for your passport, excess cash, and valuables. When using transportation, opt for tuk-tuks and taxis from reputable providers, particularly at night. Stick to well-lit roads after dark, and consider traveling in a group whenever possible for added safety.

Immersing yourself in local life by visiting the floating villages on Tonle Sap Lake or exploring the vibrant Old Market and Night Market are also essential activities for a comprehensive Siem Reap experience.
