This is a tacky tourist trap. But if you know that from the start, you can still have a nice visit gold-panning. We'd seen other gold-panning establishments where the dirt you buy is 'seeded' with gems from around the world. We hoped this might be a little more authentic.
You have to pay $1 each for visiting the 'museum mine' - a clear rip off as the 'museum' comprises a shed with unidentified old tools in it. The information boards are illegible, and I left no wiser about gold-panning from the museum than when I arrived.
However, we decided to do the gold-panning experience since we were in Alaska. The owner demonstrated how to pan and it was good - we enjoyed sifting our dirt over the sluice trough and spotting our grains of gold which we got to keep. He showed us the techniques, it was a lovely sunny day, and we enjoyed ourselves.
We wish the experience had ended there, but a younger woman got talking to us and the conversation revealed a level of racial and religious bigotry I have never before experienced. We felt really uncomfortable, and being handed a handwritten tract from the Koran as we left to 'prove' her bigoted opinions against Moslems did nothing to endear the place to us.
So, despite the fun gold-panning, give this place a wide berth. Hence my very low rating.
