Rainy Day Rescue Plan

Zero umbrellas needed: science hall, indoor play city, real snow, an underground boat ride and a thermal bath finale.

When the Heuvelland drizzles, go indoors — spectacularly. Start at the Discovery Museum's hands-on science floors, let smaller kids burn energy in Kinderstad's indoor play city, then swap rain for real snow on SnowWorld's pistes. The caves of Valkenburg don't care about the weather (always 11°C), and the day ends best in warm thermal water while the rain hits the glass.
