Weekday mornings, soon after opening time, are the best time to visit the museum. This is when the visitor numbers are the lowest, allowing for quieter exploration of Hundertwasser's works. Weekends tend to see higher footfall of visitors, with both tourists and locals flocking to the museum
Vienna's peak season coincides with the summer, so expect larger crowds from June to August. If you visit during the shoulder seasons (spring - April to May, and autumn - September to October), you'll get to enjoy the pleasant weather and avoid the crowds that flock to the museum during the busy summer months.
