- Nantou city lies between the Bagua Mountains and the Maoluo River and is the capital of Nantou County. Freeway No. 3 serves Nantou City. Its name is a transliteration of the Hoanya word Ramtau with the characters chosen to complement Paktaau (北投), a district in Taipei, even though there is no relation between the aboriginal words.
