GRANDE TRAVERSEE DE L'HERAULT - SERVIES/FAGAIROLLES (ITINERAIRE NORD)
Warning: Unsecured hours
Regularly over 1000 metres above sea level, the route crosses many passes. It uses wide forest tracks and stony paths. On the borders of the Hérault department, the route makes a small excursion into Aveyron, in the territory of the Grands Causses Regional Nature Park. Please note: many steep climbs as far as Col de Layrac pass, then as far as the Marcou.
