The Marina Bay Sands area has tons of activities and attractions at night. 1 of the most popular attractions is the Gardens by the Bay, a nature park featuring lush green spaces, lakes, fountains, and winding pedestrian pathways. This park also boasts art sculptures and children's playgrounds, providing free entertainment for visitors of all ages. (Some parts of the park are ticketed, but the free ones are well worth visiting too.) Another of my favorite things to do is to walk around the waterfront, where you get a spectacular view of Singapore's skyline- there are usually buskers singing on the promenade!
