I did my second Camino in 2015 from Lourdes, to SJPdP, then onto SdC. I plan to do my next, in the Fall, from Lourdes through the Somport Pass, onto Puenta De la Reina, etc.
My second, from Lourdes, was very quiet. I also started in May. There were VERY few pilgrims - I usually had entire albergues to myself. Some of the locals were a bit, shall I say, quirky? I traveled solo. It was a great adventure, very different from the Frances. I am glad it wasn't my first Camino and that my first was the Frances (also solo) because I had a better idea of what to expect, how to arrange my time, my efforts, etc.
I know that doesn't make sense.
Anyway, my experience was that I was much more on my own if problems arose - when problems arose - because there simply weren't as many pilgrims along that route and there weren't as many services. It was challenging but quite doable. Just be prepared. The route was more rustic in many places and I depended often on my common sense and ability to read maps in French (YIKES!) rather than on signs and symbols. Be on your toes. I'm sure much has changed since 2015 and the route has become more pilgrim friendly - most of the people couldn't have been nicer!!
I'm very excited for you!! Buen Camino!!
