Walked the Portuguese four weeks in May - train from Lisbon to Castaneihra di Ribatejo (spelling is off) walked onwards to Azambuja - with the note to self "should have taken train all the way to Azambuja".
The roadside walking was dangerous and unpleasant. Plenty of dead rotting dogs in the wayside ditch that gave their very smelly testimonial to that fact of life.
After Azambuja the walk began without such noisy and fast hazards and was lovely and a delight to me. (one poster from the UK recently aptly described Portuguese drivers having only two speeds: "Fast" and "Bloody Fast". Couldn't agree more)
In Porto, where I stayed two nights, I joined two other pilgrims, and we took the bus #500 to Matasinho (last stop) - crossed the bridge and went along side the Atlantic for much of the days walk. Perfect weather, little wind (but very pesky tiny flies that swarmed about in 'attack mode' ever so often and made me feel i am back in a tropical jungle. not amusing!) and great walking on those boardwalks.
Was a splendid day. We ended up in Vila do Conde - and the next day I went off back inland, overnighted in Rates.
I have spoken to pilgrims who walked from Catedrale Se in Porto ... and were dismayed to experience just how rough, unappealing and dangerous that route was and wished they had known about the option to take the bus or metro out of Porto.
And the ones who knew about bus/metro option and still walked ... was none too pleased with themselves that they put themselves through it and would not do it again.
But of course, I did not speak to all pilgrims, and there probably are pilgrims who did not mind the busy asphalt roads or took it in stride (no pun intended).
You know yourself best and what you are able and willing to handle/endure ...
hint: perhaps you can visualize walking from Pasadena via downtown LA towards the Westside - alongside Wilshire or the I-10. If you are okay with that, while carrying the backpack on a hot day, you perhaps won't mind walking out of Lisboa or Porto.
On the Caminho there is lots of asphalt walking, no doubt. And there are also incredible woodland trails, farm/field tracks and other paths that are a marvel.
You probably enjoy those sights alot!
I took with me two set of insoles: one Montrail and another set of silicone insoles. And alternated those when needed. Thought of it as switching winter tyres and summer tyres
By a host I was told about a pilgrim who had two sets of shoes with him: one for trail walking, and the other for asphalt.
People come up with various solutions to make it work .... good luck in finding yours!
and Bom Caminho !
September is my favorite time in Portogallo --- and the Vinho Verde will taste sooo good and refreshing!
very best wishes,
Claudia
