Allas Sea Pool is a very popular spot with tourists and locals right in the heart of Helsinki, next to the Market Square and the harbor. It’s a unique place where you can swim in heated pools or jump straight into the chilly Baltic Sea — yes, even in winter! Plus, there are several saunas with amazing views over the water, perfect for warming up afterward.

The complex has three main pools: a large heated fresh water pool, the cold sea water pool ( perfect for ice swimming in the winter) and a shallow kids’ pool. It’s open year-round, so whether it’s summer or winter, you can enjoy a swim outdoors with the city skyline as your backdrop.

There’s also a café and restaurant where you can grab a coffee, drink, or a meal while soaking in the atmosphere. Allas Sea Pool also hosts events like yoga classes and live music gigs in the summer, making it a lively place to hang out.

It’s easy to get there — just 15 minutes walk from Helsinki Central Station. Opening hours vary by season but generally run from early morning to late evening.

Tickets can be bought online or at the entrance, with options for single visits or season passes.

If you want a refreshing and relaxing experience in Helsinki, Allas Sea Pool is a must-visit.
