About Saaremaa

Saaremaa is Estonia’s largest island, located in the Baltic Sea and known for its rural landscapes, well-preserved medieval architecture and geological features such as the Kaali meteorite craters. The island has long been a cultural and economic centre in western Estonia.

Principal attractions include Kuressaare Castle, a 14th-century episcopal fortress on the harbour that now houses a museum, and the Kaali craters, a cluster of impact sites visited for their geological interest. Saaremaa also features traditional windmills, coastal meadows and small fishing villages, and it is used for birdwatching, cycling and local festivals.

Historically the island was contested between Teutonic, Danish and Swedish powers and later integrated into the modern Estonian state; many historic buildings and rural traditions reflect this layered past. The island developed small-scale agriculture, seafaring and services for resident communities.

Saaremaa lies off Estonia’s west coast in the Baltic Sea, separated from the mainland by straits and smaller islands such as Hiiumaa, and is reached by ferry services from the Estonian mainland and seasonal flights.

  • Kuressaare Castle: Kuressaare Castle dates to the 14th century and is one of the best-preserved medieval castles in Estonia, now functioning as a museum and cultural venue.
  • Kaali craters: The Kaali meteorite craters are a conspicuous geological feature and accessible by short local roads and trails from Kuressaare.

Getting There & Around

Tips for Visiting Saaremaa

  • If visiting in summer, catch a ferry to the small islands (e.g., Vilsandi) for birdwatching and seal colonies.

  • Explore Ring Tower (Paks Margareeta) in Kuressaare early in the day to avoid school groups.
