Take the MRT train to the Gardens by the Bay. Then walk 5-10 minutes and you will see huge SUPER trees ahead of you connected with bridges. Weekends and nights, these trees light up with a fantastic music shows. Some days of the month the city hosts concerts, dancing, and multiple events for free. You can pay an entrance fee to get up to the top of the trees and walk the skywalk bridges that connect the giant trees throughout the gardens. If you chose to stay on the ground though, there are lovely unique flowers and fish ponds to meander by. There are great views of the Marina Bay Hotel and the giant "Eye" ferris wheel of Singapore. This is a must-see stop in the city!
