What people ask before booking
How many days do you need in Amsterdam?
Amsterdam needs two days for the centre and one big museum, and four to add a second museum and a day trip. The city is small; the constraint is timed museum tickets, not distance.
What is the best month to visit Amsterdam?
April and May — The best of the year, and the only tulip window. September — Warm enough, and the crowds have gone.
Which months are worth avoiding in Amsterdam?
January and February — Grey, wet and windy, without December's compensations.
