Tunnel Tour Season 2026
Tunnel Tours in 2026
The Rhydymwyn Site is now open again.
Access
The latest update that we have from DEFRA is that The full site is now accessible with the exception of the few areas with barriers, notably the areas of the DA and the Bird Hide platform.
The keys for Buildings P5 and P6 also available & we will keep you up-dated.
Tunnels
When the remaining works are completed, we will be informed, and a revised Induction Procedure will be issued.
We understand that tunnel remediation will improve our frequency of visits, and the underground areas that we are able to visit. Details should be available from May onwards, but we cannot plan or train for any tunnel tours until the new rules and configuration are defined to us.
As soon as all of this is in place we will be able to proceed with training and visits."
We have not been able to reply to your recent messages because we were unsure of the future ourselves, but this is now mainly resolved, so we will clear our backlog.
These major changes mean we will need to restructure, re-organise and expand our current organisation.
We will contact you shortly
