I am starting my fourth Camino when I leave for the airport today to fly to Madrid. I will walk to Santiago from there, starting Thursday.
On my past three Caminos, I averaged €56 per day. BUT, I regularly stay in hostals or small hotels, not albergues. So, my daily spend is higher.
If you stay almost totally in albergues, except the occasional treat or splurge on a private room with a private bathroom, you can likely cut this comfortably to about €30 per day. Remember, individual performance and spending rates may vary...
BTW, I have used
www.booking.com for four years successfully, to secure lodging. Other than this, I use lodging web sites if they exist, e-mail, and in extremis ask someone who speaks better Spanish than me to call ahead to secure or confirm lodging, using my mobile phone.
I get bronchitis easily, and attract every foot fungus known to man if I stay in albergues, it's not personal vis-a-vis other pilgrims. I love to be around others. I just do not want their germs. Plus, I know that I snore and have to use the toilet at least four times each sleep cycle.
So, as suffering is not voluntarily in my remit, as as I am blessed to be able to afford it, I choose to stay in private accommodations, for the benefit of all pilgrims near me.
Also, allow enough money for emergency clothing buys. Everything costs more in Spain. If you find you need an additional fleece layer, for example, expect to pay a good USD 100 for a decent one. (BTW - sizes run about two smaller as marked than in the US - my US male XL is a XXL or even a XXXL in Spain). Also, have an allowance for equipment or clothing that gets lost, broken, misplaced, etc. Life happens...
The Camino does provide...but there are occasionally, gaps in coverage...
Again thanks for this. Love this Forum!!! Is that 56 euros a day including accommodation costs? Like you I will not be staying in albergues and for very much the same reasons (apart from the fungus - poor you!). I do love the company of others but I also love the peaceful time after a shower in privacy in quiet with my journal or smartphone. I am trying here to separate out the costs that I can accurately predict by booking from home and those that are how things pan out on the way. This way I feel I can work out how long I can go for and therefore what journey I can do. Emergencies are another matter - and another budget heading. If they take me over budget well so be it! I will round up all the figures anyway!
I hope this helps.
