Winter warmers: 10 of Britain's best heated lidos - AOL

A UK travel guide highlights heated outdoor lidos that keep swimmers in the water during colder months, including Portavadie on Scotland’s Loch Fyne. Originally earmarked as an oil rig, the site is now a marina with holiday homes and a leisure centre, featuring what the article calls Scotland’s biggest heated outdoor infinity pool. Facilities include outdoor spa pools, sauna, indoor pool and treatments like massages and facials, powered by a woodchip biomass generator. Other stops include Beccles Lido in Suffolk, which will heat its main pool to 28C in winter for the first time starting this year until early January and potentially through March, plus Hathersage Swimming Pool in Derbyshire with a renewed renewable heating system and Thames Lido in Reading reopened after restoration in 2017 with year-round heating.
