The name 'Tiaoshi' originates from the historical necessity for travelers to jump between stones to traverse the coastline before modern roads were constructed.
The coastline's massive andesite boulders originated from the collapse of volcanic cliffs centuries ago.
The region is part of the North Coast and Guanyinshan National Scenic Area, which spans over 12,000 hectares of diverse coastal landscapes.
The boulders act as a natural barrier, protecting the base of the steep mountain slopes from direct high-energy wave impacts.
The intertidal zone here is a habitat for various marine algae and mollusks, thriving on the volcanic substrate.
Tiaoshi Coasts is a unique geological site in the Jinshan District characterized by a narrow strip of coastal land squeezed between the volcanic Tatun Mountains and the East China Sea. The landscape was formed by volcanic eruptions from the Datun Volcano Group, which resulted in the accumulation of massive igneous boulders at the base of steep cliffs. Historically, the area was impassable by land, forcing travelers to wait for low tide to cross the rocky shore, a phenomenon that gave the area its name, 'Jump Stone' (Tiaoshi). Today, the Provincial Highway 2 runs directly alongside these boulders, serving as a primary transit corridor. The site is a key feature of the North Coast and Guanyinshan National Scenic Area, offering evidence of long-term coastal erosion and landform evolution. Its terrain is defined by rugged, moss-covered volcanic rocks that extend into the intertidal zone.

Wear sturdy, non-slip footwear as the volcanic rocks near the water line are often covered in slippery seaweed and moss.
Check tide tables before visiting if you intend to explore the intertidal zone, as high tide significantly reduces accessible area.
Stay alert to traffic, as the road is narrow and frequented by large trucks and buses.
Attempting to walk along the shoreline during high tide or heavy storm surges, as the water level can rise quickly.
Avoid climbing on unstable boulders or venturing too far into the surf; respect the natural ecosystem by not removing shells or rocks.
