Saaremaa is large enough that you will need a car to see it properly. The highlights beyond Kuressaare include a meteorite crater, a windmill hill, and the island's wild western coast.
Kaali crater is about 18 kilometres northeast of Kuressaare — a meteorite impact site dating to around 1500–1000 BCE, making it one of the youngest confirmed impact craters in Europe. The main crater, 110 metres across and 22 metres deep, has filled with water to form a lake. The site includes a small museum. The impact was violent enough to enter Estonian mythology: the medieval legends of the Sun falling to Earth may refer to the actual event.
Angla windmill hill, about 40 kilometres north of Kuressaare near Leisi, is the only windmill hill in Estonia that still retains its original character. Five windmills stand together on a ridge — four traditional trestle windmills and one Dutch-style mill built in 1927. The setting is unusual and the views across the Saaremaa farmland are good.
Vilsandi National Park protects the island's wild western coast, a landscape of juniper meadows, small islands, and grey seal colonies. The park headquarters are near Kihelkonna, about 55 kilometres from Kuressaare.
