Discover the historic Örö Fortress Island on a 5-7 hour guided tour featuring a boat ride, military sites, nature walks, and a relaxing lunch by the sea.


The tour starts in Kasnäs, where a boat departs for a 40-minute cruise across the Turku archipelago. We appreciate how the vessel glides through the crystal-clear waters, offering views of skerries and the open horizon – an ideal way to unwind before arriving at the island. The boat schedule is fixed, so timely arrival is important, and the last 20 kilometers feature winding, narrow roads, which may require some patience.
Once on Örö, the first highlight is a 30-minute audiovisual introduction. Available in multiple languages, this multimedia presentation offers a rundown of the island’s military history, its rare ecosystems, and key landmarks. It sets the context for the day, making the subsequent explorations more meaningful.

Following the introduction, visitors explore the Obuhov coastal artillery casemate in a 30-minute guided visit. The 12-inch artillery piece is a striking remnant of the island’s military significance and offers insight into the dramatic history of coastal defense during wartime. The guides are knowledgeable, explaining the role of the fortifications and how they relate to the island’s long military past.
After the military sites, a 45-minute lunch provides a relaxing moment. The meal is served either in the local island restaurant or as an outdoor packed meal, depending on weather and preference. The focus on fresh, local ingredients and the sea breeze enhances the experience, allowing visitors to savor the scents of pine forests and sea air.

The core of the trip is a 2-hour guided tour that can be experienced either on foot or by bike. The guides lead visitors along historic cobblestone roads and through 1920s fortifications, revealing scenic viewpoints and hidden military structures. The tour also highlights Örö’s diverse flora, including open coastal meadows, rare insects, and dune habitats, all shaped by both military activity and conservation efforts.
Alternatively, visitors can opt for a Finnish sauna experience or purchase the sauna separately. This flexibility allows guests to tailor their day to their interests, whether they prefer active exploration or relaxing wellness.
