Örö is in a large island in the Archipelago Sea national park in Finland. It is quite easily reachable – a one hour ferry trip from Kasnäs in Kimitoön through the inner archipelago – but still more or less by the open sea, and its sandy shores and meadows provide biotops seldom found in the rest of Finland. The landscapes are nice and there are smooth cliffs and beaches with fine sand. Many of the visitors also come for the military history.

Understand

While most services in Finnish national parks are handled by Metsähallitus, in Örö they are left to private partners. Seeing the sights and walking around are still free also on Örö, and camping with a tent is cheap.

History

Military infrastructure remain.

The island used to be a commons pasture for the villages of Hitis-Rosala. There were huts used as a base for fishing expeditions and other overnight stays. The sheltered waters were also used as temporary anchorages for naval vessels.

This changed when the Russians built a fort on the island 1910–1915, as part of the "Peter the Great" chain of fortifications defending the Gulf of Finland and thereby Saint Petersburg (similar forts where built at Russarö and Utö, and in Estonia). When Finland became independent in 1917 it became part of the Finnish defense and construction works continued.

The fort was modernized in the 1930s. In the Continuation War 1941–1944 the Soviet marin base in Hanko (leased as part of the Winter War peace treaty 1940) was within range for the heavy batteries. Örö also provided supporting fire in the battle of Bengtskär.

The coastal forts, and their artillery, long had an important role in Finnish coastal defence, but finally they were decommissioned. The island still remained a military area, used for training and supervision, until 2015, when it became part of the national park and opened for tourism. A few houses have been rented for year-round living, attracting mainly artists and authors. Some military installations are still in use and off limits for visitors.

Being off limits for the public and used for military purposes has protected many otherwise threatened natural features. As a former training area for conscripts, it also has nostalgic value.

Landscape

View to the archipelago.

The large island (200 ha, 1.5 km·3 km), surrounded by smooth cliffs, is a mostly forested sandy reef with low bedrock hills. The most precious habitats on Örö are the scorched heathlands and the sandy beaches.

In season there are several daily ferry connections from Kasnäs in the south-west end of Kimitoön.

With private vessels the guest harbour, where also the ferry quay is situated, is the only allowed entry point, unless the harbour master assigns other moorings (as sometimes in peek season). If you arrive by canoe or kayak, there is also a landing spot on the south shore, near the camping site. Anchoring is forbidden (there are lots of unmarked cables).
