Charlton Lido｜Chinese-tested 50m heated outdoor pool

Student noteA 50m heated outdoor pool in the Greenwich area, also with a teaching pool, gym, tennis courts and a 16+ sun terrace. The author found it still gets crowded on hot days and thinks London Fields Lido is more convenient if you're not living nearby. From June to September you must book 50-minute slots in advance via the Better website or app — walk-ins are only possible if spaces remain. The official water temperature is listed as 22°C.
