Hi Jay, as JohnnieWalker and Pieces have said you can walk on your own, of course. However despite the fact that a minority of people get help organising their Camino or go on organised walks I think you should consider one or the other in your planning, even if you discard the idea later.
I guess it depends on your reasons for walking and what you expect to get out of the experience.
Some people take an attitude that struggling through the Camino with as few modern day conveniences as possible is closer to the historical experience and therefore a more credible/legitimate way of doing the Camino. While I understand and respect that attitude, I don't subscribe to it.
I know that I have a less positive experience when I am tired and stressed and so I do everything I can to plan ahead and remove the sources of annoyance and I embrace sources of convenience where they are available. I suspect that there are people through the ages who have also done this.
While I accept others will have a different view, for me the biggest impediments to an enjoyable Camino are:
- injuries and blisters,
the language barrier,
stress about finding somewhere to sleep,
being over tired and not enjoying the experience, and therefore
a limited ability to socialise and meet other people.
There are a number of things you can do in advance of your trip to manage these issues, such as training, breaking in boots, learning some Spanish, etc. There are a number of things I think you can do to manage these issues while on the Camino, such as: getting your heavier pack transferred each day and just carrying a light day pack instead, using walking poles, getting accommodation pre-booked, having someone that speaks English and Spanish fluently who you can call to help if you encounter a problem that you can't solve with English/limited Spanish etc.
Either getting someone who can provide these services or walking with a group can assist with overcoming these issues is definitely worth considering in my view. I certainly will be when we do our next Camino from St Jean next year.
If you have a personality that would enjoy it more if you just did it all yourself and are happy to experience the highs, lows and discomforts as they happen then perhaps just go for it.
There is no right or wrong way, just do it.
All the best with your Camino.
Jason.
