Great road indeed, I’ve done it a few times. I usually use a slightly different route on the way going and use this exact route on the way back (as it is a dead-end and not to do the exact same route twice all the way). Gorgeous scenery thru amazing vineyards, sea and great road: Take the road to Zujana (after Dubrava), then small road coastal road to Trstenik, again small coastal road to Dingac and back to the main road thru a tunnel that gets you to Potomje.
