The valley is colloquially referred to as 'Wangyougu' because its tranquil environment is said to make visitors 'forget their worries'.
The trail directly overlooks Keelung Islet, a volcanic island located approximately 4 kilometers offshore.
The valley terrain was shaped by marine erosion acting on sandstone and shale deposits characteristic of Northern Taiwan's coast.
The area serves as a natural transition zone between the bustling Badouzi fishing port and the more secluded coastal cliffs.
Wangyougu Coastal Trail, also known as the Valley of Forgetfulness, is a V-shaped verdant coastal valley situated between Badouzi and Changtanli in Keelung. The area features a network of paved paths and staircases winding through lush grassy hillsides with direct views of the East China Sea and Keelung Islet. Visitors can observe significant geological formations, including layered sedimentary rock and coastal erosion features. The trail connects high-altitude ridge paths with lower coastal boardwalks. Its strategic location offers panoramic vantages of the nearby fishing ports and maritime shipping lanes. Vegetation in the valley primarily consists of hardy coastal grasses and shrubs adapted to the salt-laden environment.

The coastal location experiences high wind speeds; bring a light windbreaker even in warmer months.
Bring sun protection as the trail is almost entirely exposed with almost no shade along the ridges.
Carry sufficient water as there are no convenience facilities once you begin the descent into the valley floor.
Attempting the trail during heavy rain or typhoons, as the exposed stairs become extremely slippery and wind gusts are hazardous.
Wear sturdy, non-slip walking shoes to navigate steep staircases and uneven grass surfaces; stay strictly on marked paths to prevent erosion.
