To the east of Sha Tin, Sai Kung Peninsula has a few small towns and Hong Kong's most beloved nature preserve. The hikes through the hills surrounding High Island Reservoir are spectacular, and the beaches are among the territory's cleanest. Seafood restaurants dot the waterfront at Sai Kung town as well as the tiny fishing village of Po Toi O in Clear Water Bay. Take the MTR to Choi Hung and then Bus 92 or 96R, or Minibus 1 to Sai Kung Town. Instead of taking the bus, you can also catch a taxi along Clearwater Bay Road, which will take you into forested areas and land that's only partially developed with Spanish-style villas overlooking the sea. At Sai Kung town, you can rent a sampan that will take you to one of the many islands in the area for a day at the beach. Sai Kung Country Park has several hiking trails that wind through majestic hills overlooking the water. This excursion will take a full day, and you should only go if it's sunny.
