Pack non-slip socks for indoor playgrounds – and a water bottle for yourself. It gets warm in there!

Haltern am See: indoors and out

How to keep a rainy day relaxed

  • Start early: when it rains, everyone heads indoors. Arrive at opening time and you'll have more space for the first few hours.
  • Book a time slot: at SEA LIFE and LEGOLAND Discovery Centre an online ticket saves queueing.
  • Spare clothes: after a ball pit or water park, everyone appreciates dry clothes for the drive home.
  • Snacks: check in advance whether you may bring your own food – many indoor playgrounds don't allow it.
