What about crowds and costs?

December marks the start of Cambodia's high tourist season due to attractive dry weather and warm temperatures. As a consequence, the flow of tourists increases, especially around popular tourist sites.

The increase in the number of tourists leads to an increase in prices, especially for accommodation and tour services, as demand rises. Despite this, Cambodia remains an affordable destination even during peak periods, but it is worth reservation accommodation and experiences in advance to ensure availability and possibly get the best prices.

If you prefer more seclusion and potentially lower prices, however, you may find it advantageous to visit during shoulder seasons, such as late October or April, despite the greater likelihood of rain and humidity. Although December offers optimal weather, visiting Cambodia in other months can also be an enjoyable experience, especially if you are prepared for variable conditions and can put up with more unpredictable weather.
