I went there yesterday. The temperature was perfect, I didn’t see any litter (apart from some tea lights under the overhang where people had apparently been having a candlelit swim), nobody else was swimming there, although we passed a lot of friendly people on the way there who looked like they’d just been swimming. Nothing was stolen and I have not died of amoebic meningitis (I didn’t put my head under water because I know there are such dangers in all hot pools.) Maybe we were just lucky.
