Allas Sea Pool
Finland's love affair with the sauna—one of the very few originally Finnish words that are internationally recognizable—has never diminished, but this very traditional national pursuit has been enjoying a resurgence in popularity, not least with a younger crowd. You are not obliged to sample this most Finnish of activities at the hugely popular Allas Sea Pool in the South Harbour, but a dip in one of the year-round pools built into the sea—one of which is heated—wouldn't really be complete without a visit to the mixed sauna (swimsuits and towels are available for rent). The Allas concept also embraces events and concerts and has food and drinks available from the separately managed Allas Cafe and Terrace (a prime harborside sun-trap), which serves breakfast to prework bathers and wholesome lunches.
