Five of the best outdoor swimming pools in Scotland
Opened in 1909, this is the oldest heated pool in Scotland, and the only open-air municipal pool that’s still open, other than Stonehaven. It was recently refurbished but still has historic 1950s-style leisure vibes. Heated to 29C, so it doesn’t need to be a scorcher (brilliant, but can get chock-a-block). Also has a diving board and kiddies’ pool. Open May to October, and like Stonehaven has 10pm-midnight on Wednesdays in summer, right up until the end of September.
