The figure has doubled as of August 22 to 200,000. In years past, there were that many pilgrims but 9 days later and three weeks later. So, bottom line, not that many, considering. Historically, there are less foreigners - in July and August only.
What is most encouraging for those who've "been there, done that" is that in July 2017, the Frances counted for 57% of camino choices with the Portuguese "only" 18% (met less than a dozen pilgrims), the Norte 8% (saw 6 pilgrims in 40 days), the Ingles 5%, the Via de la Plata 3,5% (12 pilgrims max), the Portuguese by the Coast 2% with others less than one percent.
For those who care to discover other itineraries off-season, far from the maddening crowds, not included in official stats (less than half of one percent) is the
Ruta de la Lana from Alicante to Burgos via Cuenca, which looks quite attractive.
Yet another, truly off the map, not yet recognized by the Obispado in Santiago is
The Way of Saint James through Eastern Portugal, from the most beautiful village of the Algarve, Tavira.
