Ice-swimming is something extra-ordinary. Something you should not to skip. It might sound impossible, but once you've done it, you understand why it is so popular. Dip in the cold water gives you great feeling afterwards - you'll feel like superhuman.
In Levi you can go ice-swimming by booking a whole sauna and ice-swimming experience privately or go join in for the public sauna and ice-swimming appointments.
Please remember it is not safe to go swimming in the places you don't know and which are unsupervised.
