Note that the tour route includes stairs, uneven surfaces, and a good deal of walking. Children under 12 will not be allowed on this tour.
This tour is open to the public and free of charge. Tour group size is limited, so a spot on a tour is not guaranteed, but we will do our best to accommodate all tour requests for that day. Otherwise, you can always sign up for a tour at http://www.madsewer.org/Education/Take-a-Tour.
