The Portuguese route is difficult going from Lisbon and in places dangerous as you have to walk along the
highway (like on the breakdown lane!) Also there are other stretches where accommodations are too far apart
for me anyway like 30 km. It is also not as well marked as the
Camino Frances. That is why many pilgrims
start in Porto. If I did it again I would spend more time in Lisbon...Stay at the Poet's Inn in the trendy Chiado district.
(Above the famous Café A Brazileira) go to the Tile Museum and the Calouste Gilbenkian Museum with the best collection
in the World of Portuguese Art. I did not even go to a Fado Music bar.. and I would if I spent some more time in Lisbon.
Then take the train from Lisbon to Tomar (missing the worst of the Portuguese Camino)
and spend time checking out the Templar Castle there in Tomar --very cool town! Since your Camino will now be 500 km
instead of 628 km, you can also spend two or three days in Porto (there is also a Poet's Inn in Porto). Porto is fabulous.
My first day I thought the walking from just after the Vasco de Gamma bridge for 10 km to Alpriate is terrible
It is in the river valley and is muddy and hilly and slippery and wet...plus hardly any yellow arrows to follow.
The food on the Portuguese Camino is way better than the French Route and the people are nicer.
