I'm pretty sure a friend of mine was up at Eldon Hole this week without any issue.
I'm sure you've seen the closure list on the DCA website / Facebook. We'll try to chase up all the landowners this week and see if anything has changed. I hear P8 is okay again, despite the rope still being across the car park, but DCA will need to confirm this.
There are lots of other places which are not closed as far as we know, but the selection of a trip that avoids having to go to a farm house for a key or permission might still be a good move for the time being.
Eldon, Hillocks, Knotlow all good options for SRT. But with venues limited and number of cavers increasing, expect to have to change your plan if a venue is already occupied and it won't be possible to social distance.
For anyone reading who has not seen it, the DCA's current guidance is here: https://www.thedca.org.uk/
The current closure list is:
Ashford Black Marble Mine
Bagshawe Cavern
Devonshire Mine
All sites on Peakshill Farm (Giant's/Snelslow)
All sites on Perryfoot Farm (P8 etc...)
Peak/Speedwell system, including JH & Titan.
Best thing to do is check the DCA cave registry and social media before you go on a trip to see if there is a covid-19 closure in place.
