That'll be good thanks.
Not sure if we'll just use one place as a base though, more likely to ride & find digs on route.
That's what we did in France & Pyrenees.
Couple of routes, first is a circular route, we took the day to ride it.
Start: Cangas De Onis on N625, follow that route to Riano, there's a large lake and cafe's etc, then take the N621 to return toward the coast, goes through a really nice place called Potes, about halfway back and a good coffee/drinks stop, very picturesque, then continue on the A621 out to the A8/E70 coast road.
You can do this route either way round, great roads, lovely scenery.
Another is back in from the A8/E70 coast road, same way toward Potes on N621, go through Potes then take the CA-185 toward Fuente De. At the end of this road there is a cable car station/cafe etc. You can get a cable car up to the viewpoint, El Portal de Picos, spectacular views across the Picos, good head for heights required
Third: From A8 coast road, head in on the A634 to Coviella, then take the N625 for Cangas De Onis. From Cangas De Onis head toward Soto De Cangas on AS-114, then take the AS-262, then onto the CO-4 toward Lagos De Covadonga, good run up a twisty on good tarmac to a large lake and parking area at Lagos De Covadonga, great views again.
In the main the roads are excellent, good tarmac, great views and some interesting corners, narrow in places with overhanging rock, just keep an eye out for rocks from recent rockfall, not everywhere but the places to be careful will be easily spotted, and goats h1d1ng2, no road sense whatsoever @tu*
