The museum is extremely popular with tour groups and you will often see hordes descend and disappear as quickly as they arrived.
If you can fit yourself in between the groups or visit closer to the 17:00 closing time, it is a peaceful place to wander from pavilion to pavilion taking in the different styles over the past century.
Art buffs could easily spend a couple of hours here while those with only a casual interest could spin through in 20 minutes.
If you only have a passing interest in Balinese art, it might be better to visit the Puri Lukisan Museum in the centre of town instead of this one. If you have a keen interest in Balinese art, go to both.
