Francois, Paulo, Kers - thank you.
Kers - yes, Svartafell is seen from Bakkagerði, as the village in Borgarfjörður Eystri is called.
I was there in the year 2000... and did the round trip with my old car...
But as you show me there is a lot to see outside this basic route, so there is still a chance to escape from the (other) tourists...
In the year 2000 only the geyser was crowded ... with see 'europe in one week' travelers.
Would like to go there with snow... and then see some of the large waterfalls...
