About
Spend the day cracking open 500-million-year-old rock to find Herkimer diamonds... double-pointed quartz crystals so naturally clear they look just like real diamonds. Hammer and bags are included, and you keep everything you find. Closed-toe shoes required. Open daily 9am-5pm, mid-April through October. One of our favorite Things to do Upstate New York...
