Behind the Po Lin Monastery and the gigantic sitting Buddha statue, in the centre of Lantau Island, Hong Kong, a small path leads up to the burial grounds of some monks and disappears into the distance on the slopes of Lantau Peak (943 m), whose summit panorama invites you to a climb of about 4 km and 400 metres in altitude. The path is part of the 70 km long Lantau Trail, which crosses the entire island. It is just as challenging as the Hong Kong Trail because the path constantly goes up and down over the mountains in the centre; the humid heat doesn’t help. By the way: over the 50 km route and many thousands of metres in altitude of the Hong Kong Trail , an exclusive charity marathon to support autistic children, called the Rainbow Trek, takes place every year, where a group of 4 runners must all reach the finish line and are only allowed a 30-minute break halfway through. If that’s not challenging enough, you can turn to the Maclehose Trail over 100 km in the New Territories .
