Coll de Jau is one of the better 'lesser-known' cycling climbs of the Pyrenees range. Situated in the east of the range, in the Catalan Pyrenees, it is characterized by a narrow road winding through forest.
The climb from Axat is the less spectacular of the two sides, as it lacks the views of the more open southern side. However, it is still a decent climb, with some challenging gradients in the middle part, after passing Sainte-Colombe-sur-Guette.
Coll de Jau can be open throughout the year, but closures (usually short term) are fairly common during winter.
From the top you can descend into the heart of French Catalonia
Roads & Traffic
The road surface is generally in good condition, with no holes or crack, but it is a little bumpy at times - more noticeable when descending than when climbing.
There is very little traffic throughout the climb.
Most of the climb is in forest, but it opens up at the very top
Alternative Routes
Coll de Jau can also be climbed from the south, beginning in the town of Prades.
