One of my favorite local hikes. Between the abandoned mine, old mining relics, and a backcountry cabin, it feels like stepping into a forgotten chapter of Whatcom County history. Gold Mine Trail – Sumas Mountain This forest trail leads to the remains of a late-1800s mining operation, where you'll find old mine entrances, rusted equipment, stone foundations, and other relics from an ambitious gold-mining venture that never struck it rich. For those who continue farther, the trail also passes a rustic backcountry cabin maintained by volunteers
