My costs

I wrote down all the expenses in my cell phone. I'll post the list too, even if it's partly cryptic.

That's why I'll briefly give you the most important numbers for the entire trip without equipment:

In total, I paid around €1,150 for the 29 days with all costs, which corresponds to around €40 per day. For all accommodations I paid around €480, which corresponds to €16.50 per day (There were days where I paid nothing at all or €5 until the first night in France, where I paid €67.50 for the single room paid for one night).

I paid €133 for the outward journey with Flixbus and the train in France and only €48 for the return flight with Ryanair, so a total of €181. I have booked a few bus trips that I hadn't included here. I was hiking for exactly 3 weeks, then 2 days in Muxia, 1 day in Santiago and the remaining days in Oviedo.

I would say that I took care of myself more, i.e. I shopped in supermarkets. I didn't plan a budget for every day but always decided spontaneously.
