Transition Tube is located at the end of Cliff Passage, Speedwell Mine. At the very end, a bouldery slope rises upwards to the left, that eventually reach the base of Cliff Cavern.  The tube can be entered either from the very end of Cliff Passage or from a platform part way up the bouldery slope, both passages eventually meet and the tube continues.

The tube has been dug actively for the last few years, a substantial amount of spoil as been removed to make the passage bigger, rather than rabbit holing. Some bones have been found in the passage that are being dated. There is evidence that in wet weather a substantial stream enters from here so its a promising lead and actively being pushed.

For more information on the dig or to get involved, contact Dave (Moose) Nixon.

Victoria Aven Safety Notice - 26/09/2022

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!
