If you are looking for a 100km route that is not too demanding and offers spectacular scenery the ride to Sellaño should suit you well. The only hard part of the ride is the 5km climb of Collada Moandi. On paper the climb seems quite hard but because it’s gradient is so consistent, once you get into a rhythm it doesn’t seem that bad. The only downside to the route is that a significant part of it is on the main road N634 but since the motorway was built there is a lot less traffic. I rode it on a Sunday morning so there was very little traffic.
As is typical in Asturias a large part of the ride on the main road will follow the meandering rivers, firstly the River Piloña and then, from Arriondas, the lovely River Sella. From Arriondas the traffic should die down somewhat as the road heads toward Cangas de Onis.
Cangas Onis is a nice little Town and is most famous for its spectacular Medieval bridge that fords the River Sella.
As soon as you pass the bridge you turn right and continue on the N625. You will soon come to Caño and If you aren’t in any hurry and it’s the right time of year it would be worth stopping to see if you can see any Salmon jumping, as this is a Salmon control station. You can see them in this Youtube link: http://www.youtube.com/watch?v=Sn35LJTgFLI.
From Caño you continue on until you get to a right hand turn onto the AS-361 to Sellaño where the road starts to run along the river Ponga. This whole area is very beautiful and as you head on you are actually entering the National Park of Redes. The area is extremely peaceful with virtually no traffic and the roads are in pretty good condition. When you arrive at Sellaño you bear right onto the AS-839. This is where the only real climb starts, so it’s head down for the next 5 km. That said, as it’s so pretty here you would probably want to keep your head up but if not you have some great views to look forward to when you reach the summit.
You should take some care on the way down as if I remember correctly the descent is quite curvey. When you finally reach the bottom you will find yourself back at Sevares and on the N-634 again. From here it’s a straight and not too hard ride back to Nava where there are many nice bars and Sidrerias where you can relax and recover.
