The most enjoyable things to do here are watching the harbour scene and tasting local snacks at Miaokou. During the day, you can visit nearby sights such as Xiandong Cave, Shiqiuling Fort, Shibaluohan Cave, Baimiweng Fort and Haimen Tianxian.

Taipei 101
Taipei 101, the world-famous skyscraper in the Xinyi district, is the new landmark of Taipei City. Standing 508 metres tall, it blends classical Eastern culture with Taiwanese characteristics, and its night views are spectacular. Every year on the evening of 31 December, Taipei residents gather here to celebrate. As the countdown reaches zero, fireworks are launched floor by floor from the building, a sight both lively and spectacular.
