I will list down the things which you must do if you are in or planning to visit Singapore. Every single place is accessible via MRT ( Singapore Metro ) and local buses:
1. Universal Studios:
This place is the most fun-loving place on earth. This place has everything you can possibly imagine. Crazy rides, people walking around in costumes, delicious food and my favourite the Shrek Castle. It is on Sentosa Island which is a 15-20 minutes ride from the major MRT Stations. Cost: Full-Day Pass: S$(Singapore Dollar) 79
Tips: Book your entry ticket for the Universal Studios online, also reach there as early as possible to enjoy the queue-less rides.
2. Minion Mart:
If you are a Minion lover like me, you have one more reason to visit Universal Studios. It is a great place to buy souvenirs for your loved ones. I loved everything even when everything was super expensive there, so carry enough cash for that. Tip: It is inside the Universal Studios so I would suggest you purchase the souvenirs after you are done enjoying at the Studios. That way you won't have to carry anything and you can enjoy there freely.
3. Buddha Tooth Relic Temple:
This majestic place is a place of worship, a repository of Buddhist wisdom and relics. It has a museum too which has a very special artifact.
That artifact is an artifact of religious reverence and to honour it, they named this temple after that artifact.
That artifact is what Buddhists say is the left canine tooth of Buddha, which has been recovered from the remaining after Buddha's funeral in Kushinagar, India and is displayed within the temple. Cost : Free
4. Gardens by the Bay:
Singapore knows that it doesn't have a lot of Land so they are increasing their forest cover by making new forest within the building. Singapore is using modern architecture to make things beautiful in a natural way possible. (Fees: S$ - 28) Gardens by the Bay has two main attractions: (i) Cloud Forest Dome (ii) Flower Dome
5. National Gallery Singapore:
The National Gallery Singapore is an art museum located in the Downtown Core of Singapore. It is the most centrally located property of Singapore and it is situated right next to the Parliament house. It also has a very big soccer field in front of it. I went there in the evening and loved how everything was lit. Cost: (Fees: S$ - 20)
6. Singapore Flyer:
The Singapore Flyer is a giant observation wheel at Downtown, Singapore. It opened in 2008, it took them about 2½ years to build it up but since then it is one of the major attractions of Singapore. It is also known as giant Ferris Wheel. It has 28 air-conditioned capsules, each able to accommodate 28 passengers. Cost: (Fees: S$ - 33)
Tip: It is usually very crowded so keep plenty of time for it.
7. China Town:
China town is really an important part of Singapore's experience because Singapore mainly have Chinese population (76.2 %). If you want to experience authentic Asian vibe then you have to visit China town.
You can visit temples, buy souvenirs and try various authentic Asian and typical Chinese dishes. It becomes really beautiful in the evening when they turn on those red, orange and yellow lights.
8. Little India:
If you ever wanted to visit India, you have more reason to go and experience Indian vibe. Consider it as a crash course of India culture.
You can try Indian dishes mainly south Indian dishes and also there are many beautiful Temples in little India which you must not miss. (Free)
