Trekking through the mists of the Huangshan mountains , I came upon a young man painting the scenery with traditional brush and ink on rice paper. He smiled proudly as he showed me his work. It was indeed quite beautiful for a painting , but it paled compared to the living scene before my eyes: mountaintops surrounded by light clouds, an endless dance of wind and fog that changes alternately in the dark hills beneath. How futile it must feel for a mere human being to try to capture that , I thought.

Yet for centuries ,these mountains in the heart of China have been a destination for artists and poets , who come to commune with nature in one of its more striking pose-and struggle to replicate its beauty. Along with the artists and poets come lovers ,who grasp locks symbolic of their undying love to the chain fences that protect hikers from the steep cliffs .Seventy miles of trials wind around 72peaks , the two majestic of which are Capital of Heaven and Lotus Flower.

In 1990 ,UNESCO declared Huangshan a Cultural and Natural Property , thereby ensuring that the area’s physical beauty will be preserved forever. Pheasant and deer abound. Hundreds of plants are said to heal the body and the famous hot springs are known for their healing qualities . An hour’s meditation in one of these pools is a great way  to end a day of hiking .

The three staging areas for Huangshan visitors are Jade Screen, the Hot Spring area and the North Sea. The Xi Hai and Bei Hai ,located on different summits are three-star hotels serving Chinese and Western food as well as wine and liquor from East and West.

Huangshan may not be exactly off the beaten path , but it is on a road well worth taking.
