Discover the charm of Tankar Lighthouse Island, off the Finnish coast

Tankar Lighthouse Island, off the western seaboard of Finland, blends centuries of maritime history with pristine nature, welcoming visitors to explore trails, wildlife and seafaring heritage.

There it stands, a distant silhouette on the horizon.

A gentle breeze stirs as the ferry pulls away from the shore and heads out into the open sea. We’ve just left Kokkola, a vivid town about 500 kilometres (300 miles) north of Helsinki, on the shores of the Bay of Bothnia. If we sailed far enough, we’d eventually reach Sweden.

But today, our destination lies closer, less than 20 kilometres (12 miles) from the harbour: the enchanting Tankar Lighthouse Island.

From rocky islet to lively community

A red wooden chapel with a bell tower sits on a rocky outcrop as two people stand nearby viewing the scenery.

In the summer, the Tankar church holds services, wedding ceremonies and other events, such as concerts.

As the ferry docks, we step ashore and meet our guide, Hugo Lund, who begins the tour with a visit to the island’s small, atmospheric wooden church.

Built in 1754, it once held around 100 worshippers at a time, back when the law required weekly church attendance. A priest would row from the mainland to hold services, ensuring the island’s fishing and pilot families could meet their obligations.

Tankar’s lighthouse was first lit on October 15, 1889.

Life on Tankar in the 1800s was demanding. Seasonal populations of fishermen, seal hunters and pilots reached into the hundreds. Soil was carried over by boat to create small potato plots, and the island produced barely enough hay to feed a cow.

Seal hunting was then a crucial livelihood. Today, the island’s small museum preserves this chapter of history.

Hugo Lund works as a deckhand on M/S Jenny and as a guide on Tankar.

Lund knows the stories well. He first came to Tankar as a baby, and this summer marks his 20th on the island.

“When you get to Tankar, you know summer has truly begun,” he says.

Tankar’s iconic lighthouse

From the chapel, the path finally leads to the island’s most striking landmark: the lighthouse. Before its construction, sailors relied on a stone cairn and a beacon pole, but dangerous waters required a better solution.

Completed in 1889, Tankar’s lighthouse carries a touch of mystery about its design. Some sources suggest involvement from the same firm that built the Eiffel Tower, and the spiral staircase inside bears a strong resemblance to the style of the Paris landmark.

Originally equipped with powerful optics reaching 13 nautical miles (24 kilometres/15 miles), the lighthouse has since been electrified and is now fully automated, with a beam visible for 27.5 nautical miles (51 kilometres/32 miles). That makes it one of the brightest lighthouses in Finland.

On selected days, visitors can climb all 122 steps to the top of the lighthouse for a small fee.

From the top, the views stretch out over the sea all the way to Kokkola’s skyline.

The vast sky and endless water seem to meet, while swallows dart playfully around the beacon.

Nature and wildlife

Tankar is located just under 20 kilometres (12 miles) from Kokkola city centre. The island measures 750 metres (820 yards) in length.

Tankar isn’t just historical – it’s also home to stunning natural splendour.

A 1.5-kilometre (0.9-mile) trail circles the island, winding through juniper bushes, lush groves and rocky terrain. Straying off the path is prohibited in order to protect fragile ecosystems, as Tankar is a protected nature reserve.

In summer, sheep graze the island, helping maintain open meadows and prevent overgrowth.

More than 260 bird species have been spotted here, particularly during migration season, when the lighthouse’s beam can attract them on misty nights.

Island life today

Two people relax in chairs on a grassy yard near a weathered wooden cabin under a bright sky.

The island’s oldest cottage, known as Sjöblom’s Sauna, dates back to 1768. Originally a fisherman’s hut, it is now summer home to Brage and Nanna-Lisa Finskas.

Tankar remains a seasonal community. The oldest building, Sjöblom’s Sauna (1768), now serves as a private summer cottage, while some other historic houses, such as lighthouse keeper’s residence, have been converted into guest accommodation.

And when hunger hits, the café provides delicious fish soup and sweet cinnamon rolls.

For many, the day ends with a sauna session followed by a swim in the sea, a tradition that connects today’s visitors with generations of island life.

Leaving the island feels like leaving a piece of your heart behind.

Tankar is a place you must return to.
