One of the amazing trip we took while visiting Singapore last year was a boat trip to Kusu Island (Turtle Island). It’s somehow near Indonesia, you can see with your own eyes some Indonesian Islands (small ones). The trip is around 1 hour, takes on a tour around Singapore a lil bit & after that your reach Kusu, where you’ll enjoy 1 hr going through the island! It’s very very small but very beautiful! Many people visit it to enjoy a swim in the sea, too bad we didnt know about that until we saw the people swimming! Maybe oneday 
It’s worth visiting …
