Ullung is one of the most eastern islands of Korea, 120km away from mainland. It's a volcanic island, very rocky with steep hills. Takes 3.5 hours by fairy from Pohang city (Kyungbuk province). The island has several ports: even it's a small island, you can move from one port to another to make routes around. However, it's also fun to take local buses to make random trips around. Don't expect anyone you meet to speak any word of English, but there's no need to worry. It's too small to get lost.
