I didn't have much opportunity to prepare, when I decided to go two days later I was in Spain and walking so never really had the opportunity to buy a guide or do much research.
I really did not miss it at all. I had no real idea where I was going, I literally just started following the arrows. Every day was an adventure, I knew nothing about what was coming up, I didn't know if it was going to be climbing, asphalt, forest... There was a surprise every mile. OK, there were a few places where I felt stuck in a landscape that just went on with no escape (I'm thinking about a few of the urban sprawl type places) that may have been made mentally a bit more bearable knowing how much was left but by and large for most of my walk I really did not regret not having a guide.
I met so many people who, when asked their plan for the day, would point to the map from
Brierley and say from the bottom of the page to the top. Fine if that's for them, it's not for me. Everyone is different and if you want a guide then take it. I just used the Godesalco website to print a list of towns along the route (it lists every town, distance between them, distance from the start and what facilities are there: bars, restaurants, albergues, hostals, etc). I'd set out every day with an idea of the distance I wanted to cover and keep going until I found somewhere with a bed.
I honestly don't think a guide would really have made my trip any better, if anything the uncertainty of it all enhanced it for me. It was, like I said, a real adventure into unknown territory. A few people mentioned that the
Brierley guides got a bit too spiritual and preachy in places too and I didn't really want my thoughts getting shaped by what I'd read. It was available in plenty of places and I never felt tempted to buy it although a few walkers seemed rather disturbed that I had no info with me (including a lovely Irish pilgrim who gave me possibly the worst map I've ever seen because she was so concerned
).
If you are taking a smartphone then there is a very good 33 day guide here
http://www.galiciaguide.com/Camino-de-Santiago.html. I just made PDF's of the relevant pages on my PC and copied the PDF's to my phone where you can view them with the Adobe app. Doesn't give maps but it's no real loss for it. It gives a lot of good background on the places you pass through, things to see, etc.
Alternatively, Cicerone do an ebook version of their guide which you could put on a phone:
http://www.cicerone.co.uk/product/detai ... es---spain I don't know what it's like but I have a few Cicerone walking guides for other places and they are all generally very good. Definitely seem to stick to fact and geography rather than straying into mystical rambling territory.
