In reply to PaulTclimbing:
To be honest, I think your main problem is travel restrictions. If you can get to France, you'll probably be alright. They are saying they want to avoid any other national lockdown and have previously said they don't want to put restrictions on internal travel.
They could reverse it of course but hopefully once the vaccine (eventually) gets rolled out, things will start getting better.
But all countries are very keen to avoid new strains and imported cases, so while the internal measures will start to get lifted, border and travel restrictions are likely to be maintained or strengthened. Might be ok if you can quarantine and so on but, again, could be different rules for countries outside Schengen.
I mean you can go climbing in France as it is and I don't really see that changing as we get into the spring and summer, although there is the possibility of another local or national confinement. If the curfew remains in place and the lifts/huts closed, it will restrict what you can do though.
The rules here have been pretty straight forward, it's either confinement or more recently a curfew. None of this you can meet outside with less than 6 other people (unless they are children or have a dog) or 8 if you have a bubble and as long as it's a full moon and you're in your own council area, but are exercising and not having a coffee business.
