A challenging two day thruhike in the Double Haven geopark in the far north east New Territories, this one will see you swim and coasteer three remote and beautiful islands - Double Island, Crescent Island and Crooked Island. The risk-reward is high on this thru-hike. With some tough and dangerous terrain to navigate and some swimming through busy channels, injury is almost guaranteed. But you'll be rewarded with some of the most beautiful landscapes in Hong Kong, deserted islands and crystal clear waters unsurpassed in any other part of Hong Kong. Just don't try this one alone.
