As some have said, no it’s not a rule, however…
Way back in 2013, Yeah, the good ol days
my first Camino, I too walked in September from SJPdP. I was so green and thankful for it. Back then not much reserving ahead was done, at least I didn't know it was a thing. I didn't have a cell phone so it never occurred to me, I stayed in municipal albergues and just a few private ones.
SJPdP was full, the volunteers at the pilgrims office did their magic and managed to get all of us that arrived on the late train a bed. Mine was in the attic of an Albergue (see photo) with two twin beds, I shared the space with an Irishman. A great way to start a Camino.
The next day Zubiri was full except for the one bed (my bed) at the first Albergue you come to on the right after you cross the bridge, I was exhausted and thankful for it. Surely one of the benefits of walking solo. A lot of pilgrims walked on or took a taxi to Larrasoaña. I felt bad for them. So, the bed race was on. You will find your rhythm. I quickly learned that leaving early, most times in the dark, suited me. I also learned how to be a ninja on stealth mode while doing so. Yes, I was quite as a mouse. I was so grateful to have gotten a bed every place I stopped, sometimes the last bed, again in Hornillos. I did see mats put down in a few places I believe it was Los Arcos in the gym they laid down mats, and Carrion de los Condes comes to mind. I recall a lot of people in the stairwell. It was crowded then and it is crowded now. In the summer 2019 I did book ahead only after Sarria, it was crazy crowded (see phone), but it was summertime with a lot of locals walking.
Things are changing on the Camino, rapidly. Do what feels natural for you. You’re going to have an amazing time, let go and keep walking.
I’m hoping and praying for another
Camino Frances. But, I’ll definitely try to go when less crowded or is there even such a time anymore?
I’m so excited for you, Buen Camino and God Bless!
