• Book a time slot online before you go, since free skiing needs a reservation and the desk takes debit cards only, no cash
• Rental skis and snowboards can be added when you book, so kids can come without their own equipment
• Lessons from age 3 for skiing and age 4 for snowboarding on the 3-week course, with 55-minute sessions for ages 3 to 6

SnowWorld Zoetermeer is an indoor ski center on real snow, kept at -5 degrees all year. It has four slopes: two 140-meter blue runs for beginners, a 300-meter red run that is the steepest indoor slope in Europe, and Kinderland, a 30-meter green slope with a belt lift for the youngest skiers.

Next door, Adventure Valley adds climbing routes, zip lines and a 17-meter indoor climbing wall.
