Camino Frances 8-10 days- where suggest start?

Hola Pilgrims,
Have opportunity to sneak a few days on the Camino. Only have two days to get logistics together. :?

Where do you suggest to start with about 8-10 days to walk? This is my 3rd Camino, but have not trained like in previous two. Definitely do not want to climb O'Cebereiro.

I depart to Germany in two days! Then later, flying to Barcelona and taking train (??) to the Camino on Apr 17th. So transportation needs to be considered.

I don't want to miss an opportunity to be on the Camino one more time, even though it's just a few days. Appreciate your input. And as always,

!Buen Camino!

Bus/transport from Ponferrada to Samos or Sarria

Hola,
Got train schedule from Barcelona to Ponferrada. Does anyone knows bus/local train from Ponferrada to O'Cebereiro and or Samos?
Tried monbus website, but it doesn't appear to be the one.

Thanks!
