Hi Celine, If I may give you my opinion. First I would go to this website and download this app called Alert Cops. I have it on my telephone. If you have an emergency. If you are really completely lost, or injured or feeling completely alone or unsafe you can turn this app on and you will be put in touch with an English speaking person who can guide you or send you help quickly. There is a GPS on the app so the Police can find you in an emergency. The app is free and was developed by the Spanish government.
I believe that you will need to have a cell phone and internet connection that is active in Spain to use this app. I always get a Spanish SIM card before I go. I use the Mobil company called Orange because their plan works best for me. I think in 2019 it was $20 Euros for a month. It has to be renewed every month. The three biggest companies are Vodafone, Orange and Movistar. I would go with either Vodafone or Orange, because they are the biggest and have the best coverage and also have the most locations if you need help or need to recharge.
I think as a first time pilgrim and because you have doubts and fears you should walk on The
Camino Frances. It has the best infrastructure. There are many, many places and choices of where to sleep and how you want to sleep. There are the most people so you will have a much greater opportunity to meet your fellow pilgrims. The choice between going alone or on a tour is difficult and can only be made by you,
But remember EVERYONE HAS ANXIETY AND FEAR before their first camino. I have some and I am going to walk my 6th Camino in October. You will be amazed at how quickly your fears will get less and less as you take each step. The biggest advantage of walking alone is you can walk your own camino without anyone telling you when to start or stop, where to sleep and where to eat. Believe me on the first day with just the smallest amount of effort you will meet other pilgrims who need compassion, love and encouragement just like you. There will even be more pilgrims ready to share these things with you.
If you are alone and are worried about your safety or you have a feeling something is wrong. Stop and wait and walk with other pilgrims. On The
Camino Frances another pilgrim to help you feel more secure is probably just a few moments away.
Read and learn and focus on the excitement and let the experience just happen. The more expectations you have the more stress you will put yourself under. Just take the first step and go.
