The Haute Randonnée Pyrénéenne (HRP) is a high-level long-distance trail in the Pyrenees joining the Atlantic and Mediterranean.
However, where the GR 10 and GR 11 stick mainly to lower routes and mountain passes on the French and Spanish sides of the border respectively, the HRP follows a high course through the mountains and cols, frequently crossing the border to follow the highest walkable route.
Many variations on the original route proposed by Georges Veron are possible and described in the guidebook, as well as some easy summits (Aneto, Vignemale).
Joosten's published version of the route deviates substantially from Véron's and both offer variants to their main itineraries.
A digital (gpx) version of Joosten's guide, improved and expanded, can be obtained from www.hrpguide.org with all proceeds going to a Himalayan earthquake relief fund.
