The sauna is the epitome of Finnish culture, and in Rovaniemi you can experience it the traditional way: a wood-fired sauna by a frozen lake, followed by a bracing plunge through a hole in the ice beneath a sky full of stars.
How the ritual works
You heat up in a hot (70–90°C) sauna, then step out and lower yourself into the icy lake (or roll in the snow) for a few seconds, then return to the warmth. The hot-cold contrast is invigorating and, many say, addictive.
Why Finns love it
Sauna is a place of relaxation, socialising and ritual in Finland — there are more saunas than cars in the country. The ice dip is believed to boost circulation, mood and resilience.
Is it safe?
For most healthy people, yes — the dip is brief and supervised. Listen to your body, don't stay in the cold water long, and warm up properly afterwards. Skip the ice plunge if you have heart or circulation issues.
Pair it with the aurora
A lakeside sauna is the perfect way to warm up before or after a Northern Lights tour — and on clear nights, the aurora may appear over the lake as you soak.
