The Wormhole (中文版：蚯蚓坑) is slot canyon in New Taipei City, Shiding District. The canyon is 120 meters long, and deep the entire way, so to get from one side to the other you have to swim the entire way. There is a waterfall on the south end. Upstream from the Wormhole are several smaller canyons and deep swimming holes. The walls are lined with interesting rock formations.
