Founded in 1957, Viidumäe Nature Reserve covers an area of 26 sq km, with a 22m observation tower on Saaremaa’s highest point (54m). The tower (about 2km along a dirt road off the Kuressaare–Lümanda road at Viidu) offers a panoramic view of the forest and the wonders of the island itself. The view is particularly memorable at sunset. There are two nature trails (2.2km and 1.5km), marked to highlight the different habitats of the area.
Viidumäe is a botanical reserve, its favourable climate and conditions making it home to rare plant species. At the reserve’s headquarters, near the tower, you can see a small exhibition on the subject.
