The Swam Lake runs along the Singapore Botanic Gardens. All you have to do is head to the Botanic Gardens Tanglin Core, located at the Tyersall Avenue entrance, to witness this magnificent lake. Earlier on, the lake was named and known as the FIrst Lake or the Main Lake and was constructed in 1866. Therefore, Swan Lake is the country's oldest water body. Also, make sure not to miss out on the bronze sculptures that depict the Flight of the Swans. This sculpture was installed back in 2006 and is located right at the heart of the Swan Lake.
