A photo taken on March 21, 2015 shows cement pipes that are now guest rooms at Tiger Hill in Ruyang county, Luoyang city, central China's Hunan province. Now a popular outdoor sports and camping site among hipsters, Tiger Hill went through a makeover to transform its old houses and discarded grasslands to better use. Visitors now can enjoy rock climbing, fishing, gliding and archery. The site also has fields for racing cars and motorcycles and horseback riding. The country-style bars, music square and unique hotel rooms built on the existing facilities make the destination a more interesting place. [Photo/IC]
