Essential information Standard tours take two hours and are not suitable for children under eight years old. (At weekends and during holiday periods we offer one hour tours more suitable for families with younger children but are still not recommended for very young children and babies.) Tours start and finish in the Ouseburn Valley. The Tunnel is a dark, confined space (in most places it is six feet 3 inches high by seven feet wide), so we provide hard hats and torches. The Tunnel is damp and muddy in places. Please wear suitable, closed-toe shoes. High heels are not advisable! The Tunnel has a constant temperature of 12 degrees C. The walls are limewashed in places. We recommend that you wear a washable, warm jacket. No animals are allowed in the Tunnel except trained assistance dogs. Eating, drinking and smoking are not permitted in the Tunnel. We reserve the right not to admit anyone who is under the influence of alcohol. The Victoria Tunnel is an unfunded and not-for-profit project. In order to cover its running costs the following charges apply, Adults £9 (£7 for one-hour tour), Children 8-15 £4. A concessionary charge of £4 for visitors on a low-wage may be available - please phone to arrange. Tours are delivered by a team of Heritage Volunteers. Our guides are all volunteers and without them giving up their time the tours would not be possible. Please treat them with respect.
