When is the best time of the year to visit Guilin and how do you get there from Hong Kong?

The optimum time to travel in Guilin is from April to October. However, try to avoid the two golden weeks, namely May Day (1 May to 7 May) and National Day (1 October to 7 October), when all the people in China seem to move around. The best way is by air from Hong Kong to Guilin.
