Elected the main road for the walk over, as the back trail was terra incognita, and when carrying the full knapsack, I prefer the better-trod paths. (Though I did walk across a very narrow top of a dam once on Holy Thurday in a park in Budapest, similarly laden, in-between the Szecheny baths and the Basilica for Mass.)
Specatacular scenery hereabouts, but I suspect that vehicle emission standards aren't tooo stringent in these parts.
