How to do and what to expect if travel to Cambodia in October

Rainy season is coming to its end with rainfall decrease on all part of the country making October a rather pleasant month to travel in Cambodia. 
The weather is now changing to dry season with cooler weather and the country nature is so fresh with lush greenery.  Lakes, mangroves and forest are now full of life. Cruises on rivers and lakes, particularly the Tonle Sap, at their full level along luxuriant nature proved to be an outstanding experience. The low number of visitors at sites is also an advantage for those who want to escape from the crowds.
October is more suitable for easy and comfort travel rather than big adventure since remote rural areas, the northeast in particular, though quite dry now but after few months rainy condition have not recovered yet especially roads and can make your travel slowed considerably. Of course, you still be able to travel about anywhere, it just take longer and sometimes a bit difficult.
Beaches on the south coast now start to get back to their favorable condition especially from the second half of the month.
