Portugal's vulnerability atm is that it has only one land border, and that's with Spain! When I was at the Portuguese/Spanish border mid June, trying to travel back overland to UK, it was to have been closed until 1 July - but all other borders were to have opened on the 21st (land border with France and all visitors by air from Schengen countries).
I ended up crossing on 17 June with a 'transit document' after being turned back twice at a different crossing point. Just mentioning this as policy seemed to be subject to whimsical positioning and shifting goalposts.
Other than that, I think Portugal is a great place to be. Out in the Algarve hills, the coronadrama was very distant and the land provided deliciously :).
I'm just hoping the border is open, it is ATM at least, and once I get there I'm fully anticipating there to be very little Covid drama!
The pandemic definitely isn't a help, not a lot I can do!
