The northern end of Sai Kung Peninsula has several wonderful hikes that will take you through some of Hong Kong's most pristine scenery. The breathtaking 12km Tai Long Wan Hiking Trail, which starts from the end of Sai Wan Rd and passes through beautiful coves including Sai Wan, Tai Long Wan and Chek Keng, is a perennially popular option. On weekdays you’re likely to have the trail to yourself. The walk takes five to six hours.
Take the village bus 29R at Chan Man Rd (the stop is in front of McDonald’s), get off at the last stop – Sai Wan Ting (西灣亭), literally West Bay Pagoda – and start the hike there. Departures are more frequent on Sundays and public holidays. A taxi ride will be less than HK$160. The trail ends at Pak Tam Au, from where you can catch a minibus back to Sai Kung town.
