We had a great time exploring these tunnels in wet weather! I suggest you keep the torch in the dark so you feel safe. It was a fairly steep climb on the tracks. The staff were very friendly and helpful, they would do everything we could to meet. It was quick and easy to move on (just watch the oncoming car). It's full of history, it's very interesting to come here, it's full of fun. Don't forget to watch the scenery on top of the stone building so you can get an overview of it. It's great for a family to have a picnic here. Good idea!
