The 'Yin-Yang Sea' color contrast is caused by iron sulfide minerals reacting with seawater in the adjacent bay.
The trail passes near the remnants of the old Taiwan Metal Mining Corporation infrastructure.
The lookout is part of the larger network of historic mining trails in the Jinguashi area.
Its elevation provides a unique angle looking down upon the abandoned industrial sites and the coastal highway.
Baoshishan Lookout is a clifftop vantage point in Jinguashi offering panoramic views of the Pacific Ocean and the Yin-Yang Sea. The trail consists of a short, well-maintained wooden boardwalk and stair system that terminates at a viewing platform. From the summit, visitors can view the remains of the historic 13-Layer Ruins, a former copper processing plant. The terrain features natural rocky outcrops typical of the Teapot Mountain geological formation. It provides a vantage point for the distinct yellow-hued waters caused by natural mineral deposits near the shore. The site serves as an accessible alternative to the more strenuous hikes in the nearby Ruifang mountain range.

Bring a windbreaker, as the exposed summit is frequently subject to strong coastal gusts.
Carry adequate water, as there are no amenities or vendors located on the trail or at the summit.
Wear closed-toe footwear with good traction, as the wooden stairs can become slippery during frequent coastal mist.
Do not attempt to hike the unofficial social trails branching off the boardwalk, as they are steep and prone to erosion.
Stay within the marked wooden boardwalks to protect the sensitive local soil and rock vegetation.
