I found a really great website the other day called Abraham's Path that I think is quite interesting. I first heard about it through a TED video by William Ury titled "The walk from No to Yes".
I think it's a great idea and it's definitely something I would love to go on one day.
It also reminds me of The Way of St James, a religious pilgrimage that takes place in Northern Spain, the route of which has been adopted by people of all sorts of religious and spiritual backgrounds.
There seems to be something about walking along a certain path that connects you with history and takes you on your very own quest for meaning.
