• Summer season only, since these are outdoor pools that close outside the warm months, so check the season has started before you go
• Avoid noon to 5pm on very hot days: the institute that runs the pool flags that stretch as the riskiest, so mornings or late afternoons suit small kids better
• Lifeguards and a doctor from the institute are on duty at the pool whenever it is open to visitors

An open-air summer pool complex at the Sports Center Košutnjak, run by Serbia's Institute for Sport and Sports Medicine. The headline pool is the Olympic one.

The complex sits inside Košutnjak, a park-forest that belongs to the largest stretch of green right next to the built-up city.
