An engineering marvel I’m not sure any written review will ever do justice to the experience of actually setting foot in the Williamson tunnels. From the enormity of the vast tunnels to the enthusiastic and infectious commentary of the knowledgeable guide Mandy. It was all unmissable. My wife and I both live in Liverpool, and now we are retired we have more time to visit our city and a visit to Williamson tunnels was always on our list. We are so glad we have done it now. My only disappointment is that such a wonderful treasure in our city is not funded by the council or some sort of trust. It is all down to donations. Mandy passed on her local knowledge of the area and the tunnels making the trip even more enjoyable.
