Hampstead Heath's Bathing Ponds are iconic. The Ladies' Pond and Men's Pond are the UK's only lifeguarded open water swimming facilities that are open to the public every day. There's a Mixed Pond that's open to the public in the Summer (and swimming club members in the Winter).

In the Lake District, Shap Swimming Pool sits nearly 1,000 feet above sea level, so it's thought to be the country's highest heated outdoor pool. Run by volunteers, the pool is heated to 26 degrees, and there's a baby pool as well as picnic tables and benches, plus a small shop for refreshments.

The river-fed Chagfood Swimmin Pool sits within Dartmoor National Park on the banks of the Teign.

If you want to swim in the sea but not be in the open water, then the part-natural, part man-made Bude Sea Pool in Cornwall is for you. The Atlantic tops it up twice a day. It's free to visit, but is run by a local charity that relies on donations to keep it open.

Many of the UK's lidos date back to the 1930s, but Lymington Sea Water Baths goes all the way back to 1833. The 110-metre open-air sea water bath is the oldest in the UK, and is also one of the largest of its kind.

Dating back to the 1930s, the lido closed for several years, before being restored in 2007, along with the original Art Deco building.

The water is heated to 23 degrees, and in addition to the 40 metre pool there's a wet play area for kids, a cafe, and a sun terrace.

Dating back all the way to the 1860s, Pells Pool has the distinction of being the oldest freshwater public pool in the country.
