Overview
Opened in 2016, Allas Sea Pool is a floating pool and sauna complex at Helsinki harbor where you can experience Finland's traditional sauna-and-sea ritual in the heart of the city. Heated 27°C main pool, kids' pool, and a sea pool fed directly by the Baltic (about 15°C in summer, 4°C in winter) are open year-round, alongside three traditional Finnish saunas (male, female, mixed). Take the Nordic plunge into the Baltic after sauna, and admire Helsinki Cathedral and harbor views from the rooftop terrace. Admission about EUR 20. Right next to Market Square.
Opening Hours
06:30-21:00 (varies seasonally).
Travel Tips
Winter sauna + icy Baltic dip is the true Finnish experience. Bring your own swimwear and towel (rentals available).
