The only positive thing about this pass is its relatively moderate gradient. The traffic (until the road to Andorra turns off) is horrific. Hordes of motorcyclists, trucks, cars... If you can, you should avoid this pass.

Very steep. Only the last few kilometers flatten out a bit. Moderate view at the col. Lots of pro cyclists spotted along the way.

Although limited to 70 km/h, the tunnel is not passable by bicycle. There's even an electronic toll system.

For me, Encamp is my favourite training pass. It is demanding at first but then it becomes more bearable.
