Mineral is a small unincorporated community in Lewis County, Washington just off State Route 7 near the Pierce/Lewis county line. Mineral originally began as a mining town. Prospectors searching the area for gold instead found coal and arsenic. Though the mines failed early in Mineral's history the town found new life as the site of a logging camp and sawmill, both of which are no longer in operation. Today, Mineral's main industry is tourism, primarily through recreational fishing. Mineral has a post office, two churches, one general store, one tavern, a log lodge (in the National Register of Historic Places) a resort with fishing docks and boat/pontoon rentals and two bed and breakfast facilities. Mineral is the location from which the Mt. Rainier Scenic Railroad now operates.
Mineral is most noted as a fishing destination. The lake is stocked yearly with rainbow trout and other fish species. On the opening weekend of Washington's fishing season, the town more than triples in population due to the influx of anglers. As many as 200 boats easily fit on the lake. The local catch-phrase is "Mineral Lake, home of the 10" trouser trout".
Mineral is the location where one of the tallest specimens of Douglas Fir was recorded, measuring at approximately 120 meters (393 ft) high.
