How can you get to Schiphol using public transport at 5 a.m.? I understand public transport starts at 6 am.
I heard about some night buses but can't find their routes or which to take. I'm leaving from inside Amsterdam.
There are hourly trains from Amsterdam Centraal station to Schiphol all night long, every day of the week.
Alternatively, http://9292.nl/en# is the public transport journey planner for Netherlands, which should have all the options.
