Tucked between two goliath fourteeners, Mount Massive and Mount Elbert, Halfmoon Creek is a popular trail with abundant camping, great water crossings, epic views, and an amazing reward at its finish line. This seasonal Colorado trail winds through dense forests and open meadows, gradually increasing in difficulty as it follows Halfmoon Creek to the edge of the treeline, where you can explore the historic Champion Mill, a silver ore processing mill from the late 19th century. This amazingly well-preserved mill is a fascinating glimpse into Colorado's mining history that Mother Nature is slowly reclaiming.
