Twenty years ago last month I completed the Camino de Santiago. I didn't walk it, I rode it on a mountain bike, using the off-road capability to stick as close as possible to the original route. There was no English language guidebook and I met few English speaking pilgrims en route.
Things have changed. A Hollywood movie called 'The Way' is now out, but perhaps more interesting is this documentary. I've only seen the trailer, but I'm rather surprised at how many people now seem to be following the way. There are numerous guidebooks (a publisher rejected my idea for one as too few people walked it) and even baggage transfer services
And you know what? I didn't choose to do it, it found me. Twenty years on, it hasn't yet let go.
