Treasures of the Earth is a private mineral and fossil museum in Corpach, just outside Fort William. The displays are dense with crystals, gemstones, fossils, fluorescent minerals, and geological curiosities, making it a useful wet-weather stop in a town where most plans depend on mountains and views. Children tend to enjoy the color and sparkle; geology-minded adults will find enough detail to linger.
It is not a substitute for Ben Nevis, Glen Nevis, or the West Highland scenery, but it fills a different niche. Keep it in mind for a spare hour, a family break, or a day when the cloud has swallowed the hills. The location also pairs neatly with a look at the Caledonian Canal around Corpach.
