Getting There

Ryanair and Wizz Air cover Helsinki, but getting there is more expensive than to an average European airport, it’s hard to get one way flights below €50. Check Skyscanner with flexible dates.

If you’re coming from Tallinn, you can take the ferry. There are three main lines: Viking Line, Eckerö Line and Tallink Silja Line. Check both Omio and direct, prices vary. For our way in (Tallinn-Helsinki) we found the cheapest rate on Viking Line, but had to book through Omio to get €17/person.

On the way back (Helsinki-Tallinn) we found a promo for a return day trip at €10/person. We just used the first leg. Important: don’t skip the first leg of a return ferry booking. If you miss the outbound, the operator cancels your return automatically.

Here’s the full report of our Baltic trip: Lithuania, Latvia and Estonia on €18.40/Day.

Getting Around

FlixBus: Helsinki to Rovaniemi and back. We used a 25% promo code and paid €35/person for a return trip (€20 outbound and €15 return). We took the overnight bus both ways to save on one night’s accommodation each time.

Helsinki city transport: Trams and the city ferry run on the same system. The ticket is valid for 80 minutes, it costs €3.50, but it starts running the moment you purchase it at the machine – plan accordingly. We used one ticket to get to the Suomenlinna island, then we purchased another one to get back and take a tram to Sibelius Monument. After that we just walked.

Accommodation

Rovaniemi: 3 nights in an apartment, €45.40/night for two. We found it through Booking.com – it was a new listing with just a few reviews. New hosts price low to get their first reviews. Still double the Baltic prices, but reasonable for Finland.

Helsinki was a day trip – no accommodation needed.

Booking.com: Sort by “Price (lowest first)” and filter to 7.0+. For Finland especially, new listings are worth checking – the first-review discount is significant.

---

Food

€7/day per person. We shopped at Lidl and cooked in the apartment. Surprisingly, Lidl in Finland was very cheap, standard European Lidl prices – we were expecting much higher.

Route

Helsinki

We arrived on the morning ferry from Tallinn and left on the overnight bus to Rovaniemi – one full day in the city. Tallinn’s ice was already almost gone, but arriving in Helsinki we were pretty much in a field of ice floes – a special sight. Bags stored through Nannybag.

First stop after dropping the bags: a city ferry to Suomenlinna, a sea fortress built during the Swedish Empire period (UNESCO World Heritage Site). We spent around 2 hours walking around. The ferry ticket is valid for 80 minutes from purchase. On the way back, we used the same ticket to take a tram to Sibelius Monument afterwards and walked back to the city center from there.

Helsinki Cathedral is the main landmark – impressive Neoclassical Lutheran architecture. Uspenski Cathedral is the Orthodox counterpart, a short walk away.

The Helsinki Central Library Oodi is a very interesting place – opened in 2018, a community hub with games, facilities and activity throughout. Modern, very alive.

Rovaniemi

We took the overnight FlixBus from Helsinki to Rovaniemi to save on a night’s accommodation. After passing through Rovaniemi’s center, the bus ends its course at Santa Claus Village – we got off there. It’s a bit of a tourist trap, but we wanted to see it since it’s why most people come visit. It was pretty dead at early morning in March, but the 10km hike back to Rovaniemi through the snowy suburbs was very interesting. Our apartment was around 3km from the center.

Northern Lights

The northern lights were the main reason we went to Rovaniemi. They ended up being very active every night of our stay – only the last night the clouds prevented us from seeing them.

The timing was ideal. The spring equinox – around March 21 – creates peak geomagnetic activity. This trip also took place near the top of the current 11-year solar cycle.

We used Organic Maps and Google Maps satellite view to identify potential spots with low light pollution for aurora watching – it worked out very well. The first night, we walked to a spot about 40 minutes’ walk from the apartment and we saw a great northern lights show.

The second night we went to a popular spot close to the Arctic Garden in Rovaniemi. It was another great show. The first two nights had very little cloud cover. The third night the clouds came in and blocked the view entirely, even though aurora was active.

This is the system that worked for us to track the activity:

1. My Aurora Forecast & Alerts app (Android / iOS) – location-based percentage probability for the next 30 minutes. I like to just have it installed on my phone, it notifies me based on my location whenever aurora chance is at 1% or above, regardless of where in the world I am. It takes into account all the factors: solar activity, darkness and cloud cover.

2. Finnish Meteorological Institute – rwc-finland.fmi.fi – official real-time aurora activity data for Finland, updated once every 10 minutes.

3. Space Weather Live – spaceweatherlive.com – satellite data provided by NASA. This is how you read it:

The gray line on the graph is solar wind currently hitting Earth. The data to the right is what the satellite already measured that hasn’t reached Earth yet – roughly an hour of incoming data. Two numbers matter:

• Bt: should be high. Above 10 nT is good. Above 30 nT is very strong.
• Bz: should be negative. Any negative value works if you’re far enough north (Rovaniemi qualifies). At –10 nT or lower, aurora goes further south. On our first night, Bz was actually too low, below –10 nT – we saw aurora far to the south of us, not overhead. We waited – when Bz moved to around –2 nT, the aurora came back directly above us. It was amazing.

Negative Bz is required for both northern and southern lights. It doesn’t change at the poles, contrary to the common misconception.

4. Rovaniemi aurora webcam – aurorawebcams.com/webcam/finland/rovaniemi – live view of the sky above Rovaniemi. Useful for a quick check before committing to the walk.

More in Rovaniemi

We hiked the Ounasvaara Winter Trail – forest still full of snow, very quiet. We spotted mountain hares that had turned white for winter. We looked for reindeer but didn’t find any. Apparently most get herded into enclosures by local herders at this time of year.

Season

March is great timing for aurora. The spring equinox maximizes geomagnetic activity. Rovaniemi still had full snow cover when we were there – the forest and hiking trails were completely white. You can still get very cold stretches, but just as likely it can be well above 0°C.

Another high aurora activity period is the other equinox – September. Warmer than March, no snow.

December is peak season in Rovaniemi – everything’s very expensive then.

Practical

Currency

Finland uses the euro. We didn’t need to carry cash at all, our accommodation was prepaid online through Booking.com. Revolut card works fine if you’re coming from a non-euro country. Note the 1% weekend markup on currency conversion.

SIM

Finland is an EU member – if you have a EU-based SIM card, you will have data under Roam Like at Home scheme without roaming charges. Otherwise check eSIMDB for eSIM deals, sort by country, amount of data and duration of your trip.

Language

Finnish is a Finno-Ugric language – structurally unrelated to any other European language except Estonian and Hungarian. In practice, English is widely spoken everywhere in Finland, even among the older generations.

I still like to learn a few basic words to be polite: kiitos – thank you, hei / moi – hello.
