Visitors enjoy themselves at the geo park in Ma Shi Chau Special Area in Hong Kong, south China, Nov. 27, 2011. The 61-hectare Ma Shi Chau Special Area consists of Ma Shi Chau, Yeung Chau, Center Island and an unnamed islet. Home to well-outcropped rocks, the area is an ideal location for studying strata, rock properties, sedimentation features and different geological compositions. Tourists could visit along a 1.5 kilometers long route to visit attractions which highlight local geological features. [Xinhua/Song Zhenping]
