One follows the CG-2 and CG-1 through Andorra la Vella, Santa Coloma, Sant Julia de Loria and heads south across the border into Spain.
The other follows the CG-3 until Les Escaldes just before Andorra la Vella and then turns north to follow the CG-3 to La Massana, then takes the CG-4 through Erts, Xixerella, Pal and onwards over the Port de Cabus. This would then descend the Port de Cabus to the west into Spain through Tor to Alins on the L-510 in Spain. I am unsure whether the route descending the Port de Cabus to Alins is a properly surfaced road or whether it is an off-road track. I have been able to find out that it certainly was an off-road track until at least a few years ago, but cannot find any recent reference to it and wonder if anyone can tell me whether it has been made into a properly surfaced road recently. We will be on road bikes and we will need to remain on properly surfaced roads, hence my question.
Any help in getting to the answer would be much appreciated.
