On a clear day, is it possible to see France from anywhere in Devon or Cornwall?

Yes, of course. On a clear day...

Well, technically speaking, this is France:

Nice try David, but still no twinklies!

Dang! I want those twinklies!!!
How about this, then:
Distance to Horizon
Closest spot in France looks to be about 70 miles away, so if you can get up 3,000 feet or so, you have a shot at it (on a *really* clear day, of course). And if something big and very tall like Mt Everest happens to relocate to France, you won't need nearly as much altitude on your end.
So ribuck, just how high are you allowed to be in the UK?
P.S. And tell us about your interesting user name. What's the back story on ribuck?

I was briefly very excited by the radio masts at Beacon Hill and Stockland Hill, but even from the top of those, you'd need there to be an even taller radio mast on the Normandy clifftops to have a chance of seeing all the way across the Channel.

What we need is a Celtic solidarity project: twin lighthouses the size of the Shanghai Tower on Ushant and one of the Scillys.

Thanks Daniel, that's the definitive answer. Please post.
The highest place in Cornwall is 621 metres, and the highest place in Normandy is 417 metres, which gives a sight distance of 161 km (100 miles). Unfortunately, those high points are both inland, over 200 km from each other. So my next project needs to be to build twin lighthouses the size of the Shanghai Tower.
David, as for the meaning of ribuck, see:

Merriam-Webster says it's often used interjectionally, so I guess I'd better sign off with
