Built in the 1970's to alleviate issues of water shortage by constructing two dams that to connect High Island to the Sai Kung Peninsula, High Island Reservoir is one of many scenic nature areas within an hour's travel time of bustling Hong Kong. The first section of the Maclehose Trail brings you to the east dam, which is approximate to a handful of sea caves popular with the more adventurous travelers. Also, geo-tourists treasure the unique collection of hexagonal columns of volcanic rock found here, while a selection of quality seafood restaurants beckon travelers to High Island's west end.
Note:Be prepared to make a day of this adventure. Although taxis can bring you pretty close to the reservoir down Man Yee Road on Sai Kung, you'll be doing a good half day's walking if you choose to take the nearest bus route. Then again, that could prove to be the most fun.
