In Spring 2016 a group of 8 professional Canyoneers from around the world gathered in Taiwan to set a new milestone in expedition canyoning. After a disappointing start because of unfavourable weather-conditions the team set out for their goal. With very view information from satelite pictures, a rarely updated map and some local spouts the adventure began. After an epic 8 day mission the team successfully returned being the first who have ever achieved an descent that long in their sport. This is their story.
