City Hall is much closer. The entry to NGS is only 150m from the subway exit and you can then walk in A/C comfort to the main entrance point. The Information Desk at NGS is excellent for directions and keeping you out of the heat and humidity.

City hall mrt. Walk down north bridge road then turn left at Coleman st then keep walking cross over street then you will see the entrance at the side of building.

Be aware they are doing parade rehearsal on saturdays up to the 9 August in that area.

I regret using the word "route".

Which MRT station would have the easier WALK to the entrance of the Gallery?
