Palace Kämp Day Spa, Helsinki
Finns love sauna; two million citizens have them at home. Now, the new Hotel Glo has created a sauna complex for visitors. Sleek modern design includes dark wood floors, mod cabinets, Asian bamboo decoration, and frosted glass so that the treatment rooms let in natural light. The services are straightforward, with the Golden Caviar Face Treatment ($268) the most indulgent. In the three saunas and steam rooms, a mix of businesspeople and international leisure travelers practice the Finnish sauna ritualmen and women, teens and adults, all wrapped in towels together (massages, $84$141).
