Moving along Cherry Blossom Road, one arrives at Penshan Fifth Tunnel. The vein of ore excavated by this tunnel was called the Penshan Vein. Because this area in the mountains once showed exposed mineral veins in a way that made it resemble a pumpkin, it gradually came to be known as Chinkuashih, which in Taiwanese translates as "pumpkin stone."
沿著櫻花道，便抵達「本山五坑」，此坑道所挖掘的礦脈為「本山礦脈」，因所處的山區過去曾有露天礦脈形似金瓜（南瓜），當地人遂以「金瓜石」稱之，久而久之就形成金瓜石地名的由來。
