The focal point of the city has to be the serene West Lake. Surrounded by small hills, ancient temples and much of the oldest parts of the city, the lake is extremely large and divided into 5 parts by the causeways. Built in the late 1080s, the Su Causeway is the most popular and important attraction on the lake as it links the northern and southern banks. Rain or shine, cloudy or snow, the West Lake is always an amazing and wondrous sight to behold. The best time to take a boat ride across the lake is during spring when the flowers and peach trees are in full bloom. Other highlights to view are the many bridges, pavilions and little paradise island with its 4 mini-lakes, famous for its stunning water lilies and colourful lotus blossoms.
