I love your question because I have never considered “gold prospecting” but how fun that would be. I found this awesome site about Oregon Gold for you to check out! It looks like so much family fun so if you go, please let us know how it goes! Also checked this site out gold panning website. It looks like it gives some gold panning info on the “how to” and “where to go!”
I have to say that I am not a camper but my son is and he loves Foster Lake in Sweet Home, Oregon. Also, if you go to the Ranger Station in Sweet Home, they are always helpful and full of information for camping, hiking and many more outdoor activities in that area.
