The Twin Hearts Stone Weir is one of Penghu’s most recognized landmarks. It consists of two adjacent heart-shaped stone weirs assembled from basalt blocks, representing the traditional Penghu fishing technique known as stone weir fishing (石滬捕魚). Located on the southeastern coast of Qimei Island, the weirs themselves are several centuries old. Their distinctive shape has made them a popular subject for photography in recent years, and the site is now a highlighted area within Penghu Geopark. As an outer island accessible only by boat with distinctive volcanic geology, Qimei attracts both visitors and geology enthusiasts on day excursions.
What to See
Stone weirs are traditional fishing structures built by Penghu’s ancestors, who used the natural shape and properties of basalt blocks to construct traps that guided and confined fish — all without modern fishing equipment. The Twin Hearts Stone Weir earned its name because the two weir pools form a symmetrical heart-shaped outline when viewed from above. At low tide the weirs are fully exposed in the intertidal zone: the interior pools are separated from the open sea by basalt walls, creating a distinct geometric pattern. At high tide the entire structure is submerged beneath the sea. The area is a focal point of Penghu Geopark; the coastline showcases volcanic rock strata and wave-eroded landforms, providing insight into Penghu’s geological history.
Getting There and Nearby Attractions
No bus service is available. Qimei Island is an outer island of Penghu and can only be reached by passenger ferry from Magong Harbor, approximately 50 minutes each way. Allow 3–4 hours for the round trip. For schedules, fares, and ticketing, see the /ferry/ page.
Joining a Qimei Island day tour is a practical option, as tours typically include guided stops at the Twin Hearts Stone Weir, Little Taiwan, Longpi Lake, and Yueli Bay, with round-trip ferry transport included; tours cost around 800–1,100 TWD. If you travel independently by ferry, scooters are available to rent on the island (around 180 TWD), which is recommended as the attractions are spread out across the island.
