Amongst the best things to do in Singapore at night is to take in the sound and light spectacular known as the Garden Rhapsody. This free show which is held at 7:45pm and 8:45pm daily can be enjoyed at the Supertree Grove of Gardens by the Bay, close to hotels like Grand Park City Hall. The stars of the show are the illuminated Supertrees that change colour in sync to a musical soundtrack. What's more, the music played (can be classical, movie soundtracks, retro, etc.) changes from time to time so you can enjoy different experiences depending on when you visit.
