• Entrance is easy to miss: the pool sits behind two tall hotel buildings, and you get in through the outdoor ticket desk in the right-hand building
• Deep basin needs a diploma: the 33 by 25 meter pool is for certified swimmers, so younger kids stay in the shallow basin and toddler pool
• Summer season only: it closes for the year in early September, and recreational swim slots change, so check the pool's schedule before you go

Brediusbad is a heated outdoor pool on the edge of the Spaarndammerbuurt, near Westerpark, set in a quiet green spot behind two tall hotel buildings. It has a 33 by 25 meter deep basin for swimmers with a diploma, a shallow basin for younger children and a round toddler pool with a spray fountain. A lawn beside the pools has room for towels and snacks, and the whole pool is smoke-free.
