However, those of you who have walked in early March - how much trouble did you have finding lodging?
I walked in early March in 2015 on the Frances from SJPP. I was surprised at the end of the first day to arrive and find Roncesvalles almost full (not the main accommodation at that time of year, of course); I had walked form SJ in one day, but could have stopped in Valcarlos, which seemed very quiet. The next day things were full by evening in the albergue in Zubiri too. Zabaldika was closed, but Pamplona was open for business and after that more places were open than not (unfortunately not the albergue in Tosantos).
All the way along at first (before Pamplona) places to eat were thin on the ground, so it pays to be prepared and self-sufficient as far as lunch is concerned.
I wouldn't know about other caminos in March, as these days my schedule requires summer walking.
I'd prefer to walk shorter than usual stages, due to this pesky morton's neuroma.
Suggestions?
The Vasco to Santo Domingo or the Via de Bayona can be done in bite-sized chunks - this year
@SabineP and I walked the later from Irun to Burgos in 12 days (one of those days was a rest day in Haro). It was wonderful walking (and wonderful company)!
Even the Invierno can be done in relatively short stages. I took 13 days for that, not because I had to, but because I
wanted to.
Each of these walks has relatively few albergues, but pensions (which would more likely be open in late winter) were astonishingly cheap especially on the Invierno, sometimes only 20 Euros, not that much more than a private albergue on the Frances.
So...why not Via de Bayona-Frances-Invierno?
