The islets were originally part of a cape that was eroded by seawater, eventually detaching to form isolated pillars.
Local folklore refers to the rocks as 'Husband and Wife Rocks,' inspired by a legend of a couple turned into stone.
The rock composition consists of volcanic tuff, which is susceptible to the weathering patterns seen in the islets.
The islets are situated at the end of a coastal geological trail that follows the topography of the Jinshan shoreline.
The Twin Candlestick Islets are two distinct geological rock pillars rising vertically from the sea off the north coast of Taiwan. Formed by the erosion of the cape, these columns are remnants of a former mainland headland that became detached through wave action. They are located within the Jinshan District and serve as a prominent natural feature of the coastal landscape. Visitors access them via a paved trail system that runs through the surrounding park area. The site provides elevated vantage points for observing the volcanic tuff formations common to this region of the North Coast and Guanyinshan National Scenic Area. The islets stand approximately 60 meters tall above the water surface.
The viewing platform at the end of the Shitoushan Park trail provides a direct, elevated frame of both islets.
Bring a wide-brimmed hat and sunscreen as there is minimal shade along the coastal hiking trails.
Wear sturdy walking shoes with good grip, as the terrain can be uneven near the clifftop viewing platforms.
Visit during low tide to see more of the surrounding coastal rock formations clearly.
Do not attempt to descend the cliffs to the shoreline, as the rocks are unstable and the currents are dangerous.
Stay within the designated fenced trails and viewing platforms for safety and environmental protection.
