Singapore is a country that is really clean, happening, and elegant. They have a lot of things and activities to offer. You can go to Sentosa island for a beach-like experience and you can witness a night show and 'Wings of fire' which is mesmerizing. Also, they offer adventure activities.

The main attraction is Universal Studios which is a whole day tour and please carry a raincoat and eatables with you since you will not find a lot of options there to eat. Also, you can visit the Aquarium which is filled with a lot of sea life. Similarly, if you are vegetarian must visit Kailash Parbat which is a good option and must try Mango Lassi. Changi airport is also superb to see and explore if you have time for the same.
