Weekdays, especially mornings, are best for fewer crowds. Avoid public holidays and school vacations if possible.
The best time to visit Grand Assen Castle (Drents Museum) for a more relaxed experience is during weekdays, particularly on Tuesday, Wednesday, or Thursday mornings shortly after opening. During these times, the museum generally experiences fewer visitors compared to weekends or afternoon hours.
To avoid the largest crowds, steer clear of public holidays and school vacation periods in the Netherlands, as these times typically see a significant increase in family visitors and tour groups. If visiting during a popular temporary exhibition, arriving early in the day is always a good strategy, regardless of the day of the week. Late afternoons on weekdays can also be less busy as some visitors start to leave.
