There is a hot tub that is heated year round...obviously. But the main swimming pools are not heated. I understand one was kept heated through the winter until a year or two ago but there just weren't enough people wanting to swim to make the expense worthwhile.
Yep, last February we stayed there and the Jacuzzi was fine but Brrrrr the pools were chilly and there were still a couple of people doing laps in them! Those people made me jealous how tough they were!
