Bottrop, Germany
Longest indoor ski slope in the world, 640 m (Guinness World Records)
Built on a former mining spoil heap in the Ruhr, Bottrop's 640 m curving tube holds the Guinness record for the longest indoor slope. Its all-inclusive tickets with food and drink are unusual, but check dates: the hall closes in the warm months.
Pros
- The Guinness-listed longest indoor slope at 640 m
- The only indoor run with a real bend
- All-inclusive tickets cover equipment, food and drink
Cons
- No chairlift: you ride long conveyor belts back up
- Closed in summer (4 May to 30 September 2026 for renovation)
- Only 30 m wide, so it feels crowded when busy
