To answer the original poster, I would advise taking a phone at the very least. Personally, I would not dream of putting myself out of touch with my immediate family. I don't actually use my phone much for keeping in touch with friends so I don't get many, if any calls other than from my daughters and my partner. Because I kept in daily contact with my partner during my recent camino, he felt much more part of the experience and didn't miss me as much as he would otherwise have done. I think it is rather selfish to cut yourself off from those who love and worry about you. Most of us who have partners who stay at home whilst we walk are extremely lucky for the support they give us. I know my partner misses me terribly when I am away, but he has never, even for a moment, done anything but encourage me to follow my heart.
Moving on to other comments on this thread, I don't understand why people who don't have the desire to keep in touch, should wish to belittle or 'feel sorry' for those that do, by whatever means they choose. I started a blog to record my
camino Frances last year. I expected my family and maybe a couple of friends to look at it occasionally, but the main reason for writing it was to have a record of my adventure. I have an appalling memory and knew that I would forget all sorts of details if I did not record them on a daily basis. As it happens, I was very surprised and absolutely delighted when I found that not only friends and family were following my progress but also many other people from all over the world were reading and commenting on the blog, giving me encouragement. In turn I have also been told that the blog has inspired people to consider the camino for themselves.
This year I have walked the camino Portuguese, from Lisbon. The stretch from Lisbon to Porto is not very well documented by bloggers, and the majority of those I did find were rather negative and didn't include much useful information. So I have tried hard this year to give details of where I have stayed, what the ambience of the hostels was like, how stages can be split up to be more manageable, and document by words and photos what sort of countryside I have passed through, what the road surfaces are like, how scary it is to walk on and cross some of the roads. It is not at all like a travel guide, just a personal experience of my walk, the amazing and lovely people that I met, and, yes, even a few shots of very good meals I ate along the way.
During my 27 days walking the Portuguese route I received an incredible 26,000 views on the blog, with the most wonderful comments from people from all over the world and close to home, I feel I have a whole new bunch of friends, although I will never meet most of them.
Blogging is a discipline, it is an effort to write an interesting account of your day and upload photos to accompany your story, after walking 30+ km's in the pouring rain, or the blistering sun. I still maintain that I have written it for myself, but if anyone else finds it useful then that pleases me more than I can say. I think I have written a useful personal view of a camino where personal views are few and far between. I admit that I have spent many hours sitting in bars, drinking wine and enjoying tapas whilst I write and upload my blog. But, hey, I am a woman, I can multi-task, I can communicate with others whilst getting on with the job, and even had assistance from one charming Portuguese 6 year old girl who pressed the button for every photo upload one evening.
I don't need anyone to feel sorry for me for choosing to write an informative blog and for allowing my family to contact me if they want to hear my voice. I love them - I don't want to shut them out. I am already experiencing a huge change to my normal daily life by embarking upon a such an amazing adventure and don't feel the need to cut myself off. Technology is here for us all to use if we wish, or not if we don't. Why is it necessary for people to put others down because they make different choices that do not impact negatively on others.
To each their own - and long may it last!
