Have done this three times now, Into the Midnight Sun, Iceland, Australia/New Zealand last month. Go into the sauna for several minutes, then the ice room for as long as you can stand it (you are so hot form sauna it feels good). Back to the Sauna. Do this three times in each then into the heated pool. You can wear you clothes to the locker room and change in there. They have robes and slippers and locker and a centrifuge to dry out your suit. There is an ice bath and sauna in the male and female locker rooms. Some folks use these to go without clothes, not me. This is a hidden gem, so never crowded. No reservation, no charge. Everyone so friendly.
