The Camino De Santiago is one of the most enjoyable experiences I have had in my entire life. I walked it in October 2012, from St Jean Pied De Port to Santiago Compostela, about 500 miles.
You quickly become very happy walking every day and very soon begin to think about not wanting it to end. You meet fantastic people, have amazing days, walking through beautiful scenery, eating great food and wine and overall have an experience that you will probably never experience again.
If you're looking for a break, a time to reflect, a time to reevaluate, to forget work and think about what's truly important, then this is a journey you will never forget, where you will meet people who will forever remain in your thoughts.
