This was the second most impressive thing I experienced in Singapore. Although food can be expensive, at the attractions, Marina Bay Sands and Universal Studios, there are many things you can do free of charge in Singapore.
Almost every night there is the light display on large electronic trees at the Gardens by the Bay. Two times a night, at 19:45 and 20:45, the trees come alive and you can sit down on a meadow or under them and enjoy the show. There is also an elevated walkway to get close to the trees for about $8 Singaporean dollars. Classical music booms through the park and the lights run synchronously with the music. This night it was Singaporean music in appreciation of Singapore’s birthday.
