O Poio is the longest climb in the classic route of the Camino de Santiago trail. For cyclists looking for a real high mountain challenge it is probably too easy; but, when on a loaded touring bike, the gentle gradients and abundant downhill sections can be very welcome.
The first part of the climb is mostly in trees, running close to the Lamas River. However, after turning left at Piedrafita, the scenery really opens up and there are beautiful views into the rolling Galician countryside. The village of O'Cebreiro itself is very popular with travellers on the Camino de Santiago - the Santa María church here was allegedly the one time home of the Holy Grail. You almost certainly won't need any miracles or divine intervention to help you up this gentle climb, but it is an enjoyable ride and good to include as part of a longer route.
O Poio is open throughout the year, but short term closures are not uncommon in winter during periods of bad weather. Heavy fog is also common on the upper part of the climb, so it is a good idea to bring some lights and reflective clothing with you.

Roads & Traffic
The road is in very good condition throughout.
There is little traffic on the climb. The first part of the ascent to Piedrafita do Cebreiro used to be the main road through the region and was very busy. However, a motorway has since been built which has taken nearly all of the traffic, and now it is quiet throughout the climb.

Alternative Routes
O Poio can also be climbed from Triacastela in the west. This is a much shorter and steeper climb, and is usually descended on the Camino.
