Taipei Water Festival fills the school-holiday stretch at Taipei Water Park in Zhongzheng District, from 4 July through 30 August 2026. Temporary water-play kit opens in the Water Country zone, and 2026 also reopens the Aqua-Friendly Experiencing Education Area with a lazy river and large slides, plus opening events, garden parties and interactive shows. The park sits at the end of Lane 160, Section 3, Tingzhou Road, a short walk from Gongguan MRT (Green line) and the Tingzhou campus of National Taiwan University. It is a family day out rather than an evening festival — go in the morning before the August heat peaks. The last days are 24–30 August. Check the Water Park page for same-day weather closures and ticket prices before you travel; weekend queues form at the slides.
