The Lackawanna County Tour Mine Tour is a wonderful experience. It is a very educational and fun experience. They have special group tours for schools, homeschool groups, and other groups, as well as those for the general public (they fill in with the general public even on smaller group tours -- our homeschool group was small, and had a lot of others mixed in to fill the tour group openings). They are very affordable as well.
It is a fun, exciting, and educational experience -- we all loved it. You are taken deep within the mine, given a tour of what miners in the area would have seen and done in their daily jobs.
The mine does have a bit of a musty odor to it, which some in the group with respiratory issues found to be a bit irritating, but nothing severe.
It is a wonderful experience!
