This exciting tour is led by experienced professional guides from local adventure training company, ‘Howl Bushcraft’, and will last approximately 2 hours. It is a walking tour going underground exploring the hidden rivers of central Sheffield.


Megatron, Sheffield, is a Victorian subterranean storm drain, which was built in the 1800's. The culverts were built for a variety of reasons, some of which are, to build the railway station, as part of the expanding markets and structures, and to hide the open sewers.
We will be wading, crawling, and standing to marvel at the Victorian engineering, learning about the history, biodiversity and future of these mysterious and sometimes unintentionally beautiful places. 

Subject to conditions on the day tours will aim to go as far as the “Megatron” culvert.



Ticket holders must be present at least 10 minutes prior to their tour for their safety briefing and helmet provision (failure to do so may result in not being permitted on the tour without refund or compensation).

You are not required to bring your ticket with you, as we will have a registration list with us.

Safety helmets and lamps will be provided.

You will be walking in the river and water levels can be as high as 30cm in some sections so you should wear full-size wellington boots or waders (hiking boots are acceptable but bear in mind you will have wet feet for the duration), waterproof trousers (optional but ideal as you may get wet) and may wish to bring a walking pole or stick to help with balance. Please bring spare clothes (especially socks) for after the trip as you may get wet.

In view of the environment and safety considerations, participants need to be confident walking on uneven, slippery surfaces with flowing water, and happy to crawl or stoop in certain sections.

Tours may be called off in the event of high-water conditions or forecast of heavy rain. A full refund will be offered in this case or in the case that changes in government rules require the cancelling of the event. Otherwise refunds are not available. You may transfer your ticket to somebody else as long as they too are an RIBA member. You must email us about this change and provide the new participant's name and RIBA membership number.

Important: Please feel free to have a drink and a bite to eat after your tour but please do not drink alcohol or take other drugs prior to your tour. If your guide feels that you are under the influence, have not met any of the conditions mentioned above or are wearing unsuitable footwear (any footwear that is open or does not provide suitable protection or grip will be deemed unsuitable) then you will not be permitted to take part in the tour and will not receive a refund or other compensation.


No smoking or animals are permitted.
