West Lake (Vietnamese: Hồ Tây) is a freshwater lake in the center of Hanoi, Vietnam. With a shore length of 17 km (about 10.6 miles), this is the largest lake of the capital and a popular place for recreation with many surrounding gardens, hotels and villas. A small part of West Lake is divided by Thanh Nien road to form Truc Bach Lake. One district of Hanoi is named after the lake, Tay Ho district.
