Backwater Aven is located at the western end of the Long Bypass, in area surrounded by The Bung and the Far Canal. This was first dug in 1992 for a short while before leaving for grander projects. A return in July 2011, resulted in a new extension. The story about the dig can be found in Issue 154 of The Derbyshire Caver, published Feb 2020.
It had been reported to the Peak Cavern keyholders that there is a damaged section of rope in Victoria Aven - this whole area has now been completely re-rigged and the very large boulder assessed and can now again be included in the list of possible trips within the system.
However, there are still loose rocks of varying sizes which could easily be displaced and could cause serious damage/harm so please exercise extreme caution!
