Wow there are so many options when it comes to walking the
camino de santiago. How do you pick an option or where to start? I am from Australia and looking to come for my 40th birthday November 2021 for around 30 days. I want to have time to explore villages, have rest days or short days walking if wanted. I definitely don't want to feel rushed. I will be a female walking on my own. I have just started researching, but I am finding all the different routes confusing. Is there somewhere to go that compares the different routes in regard to scenery, distance etc? Thank you in advance.
As others have said, it all depends on what is important to you and how much time you have. You have given us some information. You are walking in November. You have 30 days and don't want to feel rushed but have lots of time with the option of taking rest days or short days. You will be a female walking on your own.
I'm going to make some assumptions here and provide a bit of advice based on those assumptions. If my assumptions are off, feel free to adjust the recommendations (or, of course, you are always free to ignore them!).
I'm going to assume that this is your first Camino and that, as a solo peregrina, you'd rather be in the company of other pilgrims rather than walking truly by yourself for great stretches. (Sure, you may want the opportunity to walk by yourself when desired, but you don't want to be forced into it.) Also, that you don't want to be forced into longer days because places to stay are 30+ km apart.
Right away, this eliminates a lot of options. You probably don't want to start on the Camino Levante or Mozarabe or the Ruta de la Lana, etc.
In general, for a first time pilgrim, I would recommend the
Camino Frances or the Camino Portugues. These have the best infrastructure. If you are walking in November (post season) and want the flexibility to do shorter days, these might be your best bets.
I'm also assuming that you want to get to Santiago (and perhaps beyond to Finisterre). Both of these routes can be done from "the beginning", in theory, in 30 days. You will note that "the beginning" is in quotes. Any starting place for a pilgrimage other than your front door is something of an artificial construct. There is no rule that says you have to start the Frances in St. Jean Pied de Port or the Portugues in Lisbon. Actually, the minority of pilgrims on both those routes start in both those places. And I don't think starting in either with 30 days for a first time pilgrim is going to make you feel like you have plenty of time.
So I would be looking at something like the Frances from Logroño or even Burgos or the Portugues from somewhere between Lisbon and Porto (maybe Coimbra?).
The Frances will give you a more "traditional" pilgrimage, through places that may be familiar from books and movies. You will get a variety of regions in Spain including the wide high plains of the meseta where much wheat is grown, wine regions, mountainous regions and the wet, green, cattle region of Galicia.
The Portugues will give you the option of seeing another country (Portugal) with its unique history and architecture, its own farming regions. You won't get much in the way of mountains but you will get the option of seeing seashores. You also get to walk up through Galicia, but coming from the south rather than the east, you get to see wine regions there rather than cattle regions, so the smell is better.
Both routes have a solid history, with many documented pilgrims back to the middle ages. Both have good systems of albergues and charming villages and towns and fellow pilgrims to form community with (although somewhat fewer fellow pilgrims on the Portugues between Lisbon and Porto, I'm told).
To get a better idea of the scenery, distances, etc. there are good guidebooks and apps (the apps are cheaper) or you could look at some YouTube vlogs of people who have walked them.
