Two of us enjoyed a truly wonderful tour of Guilin, Yangshuo and surrounding countryside.    Many thanks to CnAdventures for providing very helpful assistance and our guide, David, who was really terrific, both accommodating and informative.  The trip provided a great deal of variety as we hiked, biked and rafted through some of the most gorgeous countryside I have ever seen.  An unplanned side trip to the Dragon's Backbone Rice Terrace was a most worthwhile addition to our itinerary.  Another nice aspect to the trip was the opportunity to sample some excellent local food along the way--stuffed snails and sticky rice cooked in bamboo were a couple of highlights along with rice wine and osmanthus tea.
