• Closures for competitions: the pool or the diving pool shuts on some weekends for water polo, canoe polo and diving events, so check the city's page before you go
• Last entry 30 minutes early: entry stops half an hour before closing, and everyone has to be out of the water by closing time
• Swim gear for rent or to buy on site from Sauna im Norden, which also runs the bistro

Hallenbad Oerlikon is a city-run indoor pool by the Hallenstadion and the open-air velodrome. An eight-lane, 50-meter pool sits next to a diving pool with boards at 1, 3, 5, 7.5 and 10 meters.

Younger kids get a learner pool and a paddling pool with water toys, both kept at 30°C, plus an outdoor paddling pool in summer. On dry land there's a playground, a foosball table and a lawn.
