I doubt you will find many (or any) people on here who have done that...this is a forum for independent travellers (usually anyway ;-)

Spain and Portugal are two of the easiest countries in the world to travel in on your own,and so few people would consider doing such a tour...which would cost a lot more and leave you with far less freedom than going it alone..

If you can manage the camino,you sure won't need to be herded along with a bunch of other tourists

surely 'adventure tours' is an oxymoron if there ever was one...

There's nothing wrong with taking an organized tour. I've heard mixed reviews about Gap Adventures tours, though I've never taken one myself I've been told it is entirely dependent on your tour guide and group. If you get a great tour guide/group then you'll have a great time :] I would also recommend doing the trip on your own, solely because it will be much much more affordable and flexible. But if you prefer to have the trip pre-planned and already taken care of for you, or if you like to travel with a group, then a tour is for you. Note G Adventures will have a very wide range of age groups, and for some people being with a group of peers is important to them.

Actually,there is a lot 'wrong' with taking a tour ;-)

Particularly in a place that is very,very simple to travel without one...

It will cost more...usually a lot more
You have to go where you are taken...not where you like
You have to go at a speed that your guide/company says..not faster or slower
You can't change your plans when you want
You are stuck with a group of people that you didn't choose.They may be ok,or they may not..
You often have to sleep or eat in places chosen for you..which may be very low quality

etc etc.
