Admission covers the science centre, a self-guided tour of the castle, and the Star Show under the dome. Walk-ins are welcome and no booking is required. It opens every day from 10:00 to 20:00, with last entry at 19:00.
A castle and an observatory on one ticket, with no booking needed. It stays open until 20:00, so it works as an evening trip rather than a daytime one.
