One such section is that from Gavarnie to Biados. Here Joosten will send you all the way down to Heas with a road walk to the Auberge and camping that in high season is often full. Following the climb out to Hourquette Heas, Hourquette Chermentas and Barroude you descend once more through the Cirque de Barrosa to a very busy road to follow towards Parzan before which you turn up a dirt road for the long climb up to Collado de Urdiceto. In effect you have traversed through a wild, high section of the Pyrenees mostly on road and track and to a large extent low down, not very Haute Route.
There is an alternative, not for bad weather, but certainly far more interesting and within the spirit of the HRP, this would be the George Veron route.
Follow the HRP from Gavarnie through the Hourquette d'Alans and head down the Cirque d'Estaube to Lac des Gloriettes. At the southern end of the lake a bridge leads to a rising path heading East, follow this as the way becomes clearer and eventually a broad grass track that intersects the road leading to the Cirque de Troumouse, follow the road to Auberge du Maillet.
From here you will have to follow the road and/or take the paths between the hairpins until picking up the path leading to the Cabane de la Vierge. Paths abound, some human some animal but it is fairly easy to follow the curve of the Cirque in order to reach the Cabane des Aires.

Veron now takes you South on a very pleasant hike to Port de Urdiceto where we can rejoin the GR11 to Camping Forcallo or Refugio de Biados. There is also Port de Plan which will also lead on down to the GR11 and Port de la Madera which catches up with the GR11 beyond both the camping and Refugio.
