Whale Cave, Natural arch and cave in Xiyu Township, Taiwan
Whale Cave is a natural arch and cave formation along the coast of Xiyu, with an opening that rises from black columnar basalt cliffs and cuts through the rock wall. The structure creates a distinctive passageway along the coastline where water flows through during certain tidal conditions.
Over centuries, monsoon winds and seawater continuously eroded the black basalt cliffs, slowly creating this natural arch and cave formation. This ongoing erosion process shaped the coastline and continues to alter the structure today.
Local fishermen have long told stories about sea creatures living in this cave, making it part of regional maritime folklore that still influences how visitors experience the place today.
Access to this formation is best during low tide, so visitors should check tide schedules before planning their visit and timing their arrival accordingly. Comfortable footwear and careful footing on the uneven rocks are important for safety.
When viewed from certain angles, the rock opening resembles the silhouette of a whale, which is how this formation earned its distinctive name. This striking resemblance becomes immediately apparent to many visitors upon first viewing the shape.
