I´ve ridden the southern section of this route and it´s excellent; especially the D918 west from Arreau. Arreau itself is a pleasant spot for a teabreak before you set off. There´s also a restaurant on the Col de Tourmalet. A few warnings: There´s a lot of two-wheel folk around, so be aware; keep an eye out for gravel wash in road on the Arreau-Col d´Aspin section and remember to check the cols are open before you set out. Other than that this is an unmissable ride if you´re in the area.
trail guruI more or less am living in that area.I did the Cols dAspin and Tourmalet many times by car and bike. The views from those cols are great ! This is a classic tour trip in the area which is really worth it !
