Crossing the Arctic Circle: what the line is

Two weathered wooden fence posts capped with thick pads of snow, strands of barbed wire running between them, above a snow-covered slope and a distant blue horizon

The short answer

A latitude, not a place. The circle runs at 66°33′45.9″ north, and in Rovaniemi it crosses Santa Claus Village, eight kilometres north of the centre, where it is painted across the central square and free to walk over. What it marks is the southern limit of the area where the sun stays below the horizon for at least one full day in winter and above it for at least one in summer. At the line that day is a technicality: the Meteorological Institute notes that at the Arctic Circle the length of the day never reaches zero even at midwinter. Cross it in five minutes, and spend the planning on what lies north of it instead.

People arrange a day around this, and it is worth being clear about what is there: a painted line across a square, and a definition.

Where it is

The Arctic Circle runs at 66°33′45.9″ north of the equator, and in Rovaniemi it crosses Santa Claus Village, eight kilometres north of the city centre, where it is clearly marked in the central square.1

Getting there is a bus. The practicalities of the day – the storage, the hours, what is free once you are on the site – are on luggage storage and practicalities at Santa Claus Village, and the crossing itself takes about as long as it takes to hand somebody your phone.

What it marks

The Meteorological Institute’s definition is the plain one: the polar circle is the 66.5-degree parallel in each hemisphere, inside which the sun does not set for a period around midsummer and does not rise for a period around midwinter.2

So the circle is the southern limit of that behaviour. It is the line where the effect begins, which means that at the line the effect is at its weakest – one day of it, and barely that.

The institute makes the second half of the point elsewhere, and it is the fact that surprises almost everyone: at the Arctic Circle the length of the day never falls to zero, and even at its shortest it is a couple of hours. In midwinter there are still a few hours of twilight around midday.3

Rovaniemi is not inside the polar night. It is standing at the edge of it, looking in. That is the whole reason the town has usable daylight in December and the far north does not, and which month to come for the northern lights works through what that means for a trip.

Why it is not a place

A latitude is an agreement about numbers, and this one moves. The circle is defined by the tilt of the Earth’s axis, and the tilt changes slowly, so the latitude that satisfies the definition is not permanently the same line. There is no ridge, no river and no change in the forest.

That is not a reason to skip it. A line that only exists because of the angle of a planet is a genuinely good thing to stand on for a minute, particularly with a child who has just been told why. It is a reason not to build an afternoon around it.

What to do with the visit instead

Go early. The square is the same square at nine in the morning and at two in the afternoon; the crowd is not.

Do the free things. The crossing, the Santa Claus Office, the post office. Who runs the Santa visits sets out which meetings cost nothing and which are separate businesses – there is more that is free on that site than most visitors realise.

Treat the certificate as a souvenir. It is a nice one. It is not a document.

Plan the real trip around latitude rather than the line. If what you actually want is the polar night, the aurora odds or the long spring snow, the page you need is where else in Finland to see the northern lights or what changes on a tour further north. Both of them are about the consequences of latitude, which is what the line is a marker for and what the marker itself cannot give you.

This page is an independent guide. We have no connection to Santa Claus Village or the businesses on it.

Questions people ask

Does crossing it cost anything?

No. The line is marked across the central square at Santa Claus Village, the village charges nothing to walk into, and nobody stops you standing on it or photographing it. What costs money is the certificate, which is a souvenir of having done something free, and the various attractions on the same site. That is worth knowing in advance because the crossing is often sold inside a package as though it were an admission, and it is not one.

Is the painted line in exactly the right place?

It is a marker of a latitude rather than a survey monument, and the circle itself is not a fixed physical feature – it is defined by the tilt of the Earth's axis, which changes slowly, so the latitude that satisfies the definition is not the same line for ever. For the purpose of standing on it and taking a photograph none of that matters. For the purpose of believing you have stepped over a physical boundary, it is worth knowing that there is no boundary to step over.

Will we see the polar night if we go north of it?

Only a little way north, and only in the right weeks. The polar night lengthens quickly with latitude: a handful of days around Christmas at Sodankylä, and close to two months at the very top of the country. At Rovaniemi itself there is no polar night worth the name, which is why the town is usually the wrong place to go looking for one and a good place to go looking for daylight in December.
