Lonna Sauna
A Seasonal Public Sauna Overlooking Helsinki’s Coast
Situated just off the coast of central Helsinki, this contemporary public sauna is open exclusively during the summer months. Built entirely from hand-carved natural logs, the facility features two loft-style saunas heated by traditional wood-burning stoves, offering an authentic Finnish sauna experience. A generous outdoor terrace overlooks the surrounding archipelago, providing a peaceful retreat where guests can step away from the pace of everyday life.
