Wide enough for one boat, and with a towpath all the way through, the Whitehouse tunnel lies between Pontcysyllte Aqueduct and Chirk. It is an impressive 175 metres long and was completed between 1795 and 1802. It was designed by Thomas Telford and William Jessop.

With the aid of a torch, navigate yourself through this 18th century tunnel, under the traffic of the A5. It’s quite an adventure, be sure to go steadily and be aware of others on foot, or on boats!
Please dismount and use you headlight to see the path in front.
