From May 14th through October 9th, we will keep the gate open for you seven days a week, from 9:00 am until 5:00 p.m (from Memorial Day to LaborDay, we extend our evening hours until 7 pm). We don't charge admission to visit; you only pay if you play at Gem Mountain. We have three digging options. You can purchase a single gravel bucket ($14 each). Or, try our Lucky Seven Deal (buy six for $84 and get one FREE). Our Dirty Dozen Deal is even richer--buy 10 for $140 and you'll get two FREE.   You can also purchase a variety of gravel products guaranteed to contain rough Montana sapphires year-round.
