Our two boys have decided that every holiday must include a mine tour and Sierra Silver Mine did not disappoint. The trolley ride was a bit short and light on town sites but I guess thats not what we came for. Our guide Bob was very knowledgable, funny, humour for adults without being over the top and treated out two boys like VIPs. Provided an in depth tour with engaging highlights and interactives but not so much as to bore. Was impressed with his knowledge of mining all the way to Canada (Saskatoon to be exact). Absolutely worth the $45.00 for the 90 minutes or so. Will probably have to do it again the next time we are in the valley. Our boys say we have to come back.
