Planning sightseeing around dialysis
Hours are 9:00–17:00, with final admission at 16:15. From December 2026, seasonal closing days and a New Year closure apply. The trolley is used only for the inward journey; visitors leave it about 150 metres inside and walk approximately 300 metres through the exhibits. A temporary entry and exit route is in use, while visitors who have difficulty with stairs are advised that viewing via the regular gate can be arranged. Ask the facility in advance about boarding, alighting and level changes along the underground route.
