Walking is one of the best ways to keep fit and reduce your not-so-lovely love handles, but in the city you have to compete with prams, dog-walkers, other pedestrians and joggers. Experienced hikers who've exhausted the Dragon's Back and would like to find new terrain to challenge them in Hong Kong, might be interested in a discovery along the Peak to Waterfall Bay hike. A barely trodden trail, which starts outside Pokfulam park and heads through dense jungle to Waterfall Bay, is being opened up. There is a free leaflet on the existing trail, available from the Hong Kong Tourism Board, which highlights 20 geological, geographical and cultural points of significance along the way. The new option has not yet been mapped out and is not part of the official Peak to Waterfall Bay hike. However, it presents a challenge for those who prefer wandering off the beaten track and who want to experience a little of Hong Kong's wilderness: a sweaty 11.5km of it to be exact. Waterfall Bay is home to a preserved second world war bunker and a freshwater waterfall that pours straight into the ocean. So bring your bathers to cool yourself off as a reward.
