Hi there are so many experiences shared here, it's one of the things I enjoy most about this forum. Let me share some thoughts about walking the CF mid October - end of November -- a very different experience than what I read about summer walks.
I too am an introvert (INTP for the Myers Briggs'y folks out there) I have a small writer's retreat --a Thoreau - esque cabin in rural Iowa. Many writers and artists come to stay saying "I really need the solitude." But what some share with me is after 2 -3 days, the silence and lack of another person is overwhelming. Some even left their week long stay early.
Now for each of those people, I have many who love it so much they return every few months.
So about walking alone. In 2013 I began solo and quickly met groups and individuals and by the 3rd or 4th day, I was walking "with" someone most of the day. Once I reached Finnesterre, I walked solo to Muxia and returned to Santiago on foot - it was the end of October and with fewer pilgrims and even fewer who walk the reverse direction from Muxia, I saw very few pilgrims until I reached an albergue for each night.
This year, in late November, I arrived in Santiago and that day 157 pilgrims registered at the office. That gives you an idea of how few pilgrims there are in November vs July. With the exception of 3 days, I walked alone each day from Logroño to Santiago and much of the day, I did not see other pilgrims ahead or behind me on the trail. I was also very lucky on the days I walked with someone to walk with people who had great stories to share and we walked in a similar style and pace. Walking "together" to me is a bit like dancing, some partners are great together, others stumble over each other. And I'm a lousy dancer.
I did see plenty of pilgrims in bars and in albergues -- so I had a mix of large groups and solitude. And it is usually easy to join a conversation and then walk with group if you choose. And if the bar is empty, wait a bit and someone or group will be along shortly.
My experience walking alone was that I never knew other walker's daily plans. As a result I enjoyed several mini-reunions. The conversations included the sharing you described -- and since we were at the same place on different days, it was a fun to hear about it in a slightly different point of view.
For instance, the Cruz de Fero had snow -- that melted -- two days before arrived there. I really enjoyed hearing about something I hadn't seen but was a familiar place.
In three albergues, I was either alone for the night or there were only 2 or three of us, but each speaking a different language. The hospitaleros and their families were very kind and welcoming. In one albergue, where I was the only pilgrim, the family showed me how to lock the door, and then said good night and left, returning to their home.
Walking alone -- the sound is different -- the only footsteps are your own, the walking stick clatter is either just yours or none at all. The wind makes sounds that imitate music or voices. You can talk or sing to yourself as loud or quiet as you like.
I think the beauty of the
Camino Frances is that in the less traveled seasons, you can enjoy a little or a lot of solitude.
