El Cami dels Bons Homes / Trail of the Cathars GR107 (Senderos GR)

I haven’t tested this by actually walking the route yet but it’s a decent quality product if you’re thinking of walking the GR107 - breaks it down into a series of day stages with winter alternative routes, distance and elevation gain/loss per each stage. I think it’s counter intuitive (certainly counter historical) to walk this route from South to North (as this set of maps do) rather than North to South replicating the flight of Cathars from persecution in France - but that’s not a big deal. The maps lack detail if you were used to the UK Ordnance Survey 1:25000 style - it’s when you appreciate just how good those maps are……. But overall looks useful with basic information about the services available in the various villages along the route and so on.
