one of the delights of hanging around in iceland. nice free geo-thermal heated bathing pools! everywhere! but there is one important role, esp. for visitors. you must wash yourself before NAKED (if possible) before entering the pools, cause there is no chlorides eg inside.
must be even gorgeous in wintertime. and remember u don’t swim in pools, you let yourself soak in and talk, while having a cold beer!
