Just checked the location and found it (I think...).
Please see the attached pics.
In one of them you'll see a line with an end at my location and the other ot O Grove.
It looks like you're heading to a small peninsula seaside edge.
It looks almost like an island.
In fact there are a lot in this coast area.
I know very well the whole Galicia province but never been in this particular O Grove place.

Along the Route Plan you can click the various maps for the locations.
Let me check which dates I may be available and we will arrange something including a short trip to Portugal to show you around.
All this on my SVX, I hope.
