On a recent trip to Mt. Ida area, stopped in at one of the many different locations for participating in gem and crystal digs. The area is full of different options. We opted to go in to Wegner Crystal Mines, but we did not have time to do a full blown dig. We did have a wonderful time exploring the shop full of gemstones from all over the world. Prices are largely marked wholesale, so for retail, a 33% or so charge is added. I did buy a bucket of goodies to take home so that we could dig through later (comprised of a minimum number of certain types of gemstones - kinda like a grab bag). Even if you don't do the digging, worth a stop.
Mt Ida Cafe
Good, cheap breakfast while waiting on crystal shop to open. Basic, but nicely done.
Wegner Crystal Ranch Rd
If you don't have time for dig, still great place to stop and look through the shop.
