Pasir Ris station how far is this station from marinabay area?
According to an app I have about 35-40 minutes on the MRT
Why don't you just check Google maps and see for yourself.
Pasir Ris is the easternmost station on the east-west line (green). you will need to transfer between lines.
there is an express bus from marina bay to pasir ris it will take longer and is more expensive but 0 transfers.
