Tickets may be purchased months ahead online. The "I Amsterdam City Card" is valid at the Van Gogh Museum, but a time slot must be booked via the "I Amsterdam" website beforehand. Also, if you want to take a guided family tour of the museum, be sure to book the tour ahead of time.
The Van Gogh Museum is open daily. The busiest hours are from 11 a.m. to 3 p.m.
We visited during Amsterdam's high tourism season in the month of August. Even though we booked as much as possible online, there were crowds and lines everywhere. The museum was no exception. We were told April, May and July are equally busy.
Admission to the Van Gogh Museum is free for children under the age of 18. Also, anyone who is unable to navigate his/her way through the museum independently may bring a companion for free.
