For over a century, Bengtskär has guided sailors through these waters. Today, it guides travelers looking for a unique visit in a remote historic destination.
Reachable only by boat of helicopter, the lighthouse is situated on the southernmost island in the Archipelago Sea. The closest village, Rosala, is located 18 kilometers north of Bengtskär.

If you want to experience Bengtskär at its calmest, stay overnight inside the lighthouse itself. The former lighthouse keepers’ rooms have been turned into guest rooms, each with sea views. As the day visitors leave, the island settles down. Dinner and sauna is included in the overnight stay.
Bengtskär is great for animal-spotting. In the spring, eider ducks nest on the island. There were more than 550 nests in 2025. If you’re lucky, you can also spot seals swimming at the edges of the island.
During a strong storm, waves crash over the entire island. The harsh conditions make it difficult for plants or animals to survive, especially in winter, which gives the island a very unique plant and animal life.
