Monday to Friday are usually calmer than Saturday and Sunday, with mornings generally the best time to visit if you want more space in the museum’s narrow corridors. Reviews most often recommend going earlier in the day, especially for families using strollers or visitors who prefer a quieter walk-through.
Saturday and Sunday can feel busier, and rainy afternoons are the most commonly mentioned pinch point because more families switch to indoor plans. If you visit on a weekend, aim to go close to opening rather than later in the day, when the compact rooms and small play area can feel crowded.

Summer can bring heavier general tourist traffic in central Prague, and summer weekends may feel busier inside this small museum. Rainy days at any time of year also increase demand because the museum is fully indoors, so those are the times when visiting earlier in the day is most useful.
Winter is a practical season for a visit because the museum works well as a cold-weather stop and can be easily added to a central Prague itinerary. The trade-off is that bad weather also pushes more families indoors, so dry days and earlier visits usually feel more comfortable than rainy afternoons.
