Kärdla is located on the north-eastern coast of Hiiumaa, by the Tareste Bay. Southeast of the town is the Kärdla meteorite crater, which is 455 million years old. Several small rivers flow through the town. There are also artesian wells in Kärdla.
Kärdla was first mentioned in 1564 as a village inhabited by Swedes. Its growth was greatly influenced by the cloth factory founded in 1830. A port was built in 1849. Both the port and the factory were destroyed in World War II.
