We went to Rudas baths on our first visit. We'll be in Budapest end of this month and need some information on the logistics of visiting the outside pools at Szechenyi in January.

How exactly does one do this? Get locker, change, then dash outside and jump in before you freeze?

Are you given a robe or something or does one just change and put on your winter coat to go outside?

Anyone done this that might offer advice, including whether it's a really dumb idea. Greatly appreciated.
