The jetty acts as a critical sediment trap, influencing the sand accumulation patterns that form the popular surfing breaks at Wushi Beach.
The structure provides a direct line of sight toward Guishan Island, a volcanic island located 10 kilometers offshore.
Tetrapods along the jetty are periodically rearranged by the Yilan County government to mitigate coastal erosion caused by northern monsoon currents.
Wushi Harbor's name originates from the large black basalt rocks (Wushi) that once occupied the original natural harbor entrance before modern expansion.
Wushi Harbor North Jetty is a prominent coastal landmark in Toucheng Township, serving as a protective breakwater for the adjacent fishing harbor. The jetty extends into the Pacific Ocean, providing an elevated vantage point to observe the intersection of the harbor's shipping channel and the open sea. It is adjacent to a popular surfing beach, which benefits from the offshore conditions created by the harbor infrastructure. The structure is constructed primarily of reinforced concrete and large tetrapods designed to dissipate wave energy during storm surges. Visitors use the jetty as a promenade to watch incoming and outgoing fishing vessels and ferries headed toward Guishan Island. The area is a key point for monitoring local maritime traffic and surf conditions along the Yilan coast.

Bring polarized sunglasses to reduce the high glare reflecting off the Pacific Ocean surface.
Stay on the designated walkway, as the concrete tetrapods are extremely unstable, slippery, and dangerous to climb.
Check local weather alerts, as this exposed area experiences high wind speeds during typhoons or strong monsoon conditions.
Do not attempt to walk on the tetrapods (the large four-legged concrete wave breakers) to reach the water's edge, as this is a frequent site of maritime rescue incidents.
Access may be restricted by local authorities during extreme weather events or storm surge warnings.
Avoid walking near the edge during high tide or heavy sea swells for personal safety; do not interfere with active fishing gear.
