About Guilin

Guilin sits among limestone karst towers, with the Li river cruises to Yangshuo passing the most famous peaks. The Reed Flute cave, the Elephant Trunk hill and the Longji rice terraces fill the days, and the Two Rivers and Four Lakes area handles the evenings. April to May and September to October are the best months; summer is hot and wet, and the cruise boats are busiest in the golden weeks.
