After several hundred meters, you will see on the left side the sign for Kotisina botanical garden )listed here at the TA among Things to do)
Then you will come to Old Tucepi (with one of the best restaurants & with a splendid view - the Konoba Opacak tavern, also listed at the TA)
Then you come to this intersection:
To the left goes the narrower road to old Podgora:
which at the end joins Adriatic Coastal Road (D8) in new Podgora. If you go straight you would come to the entrance to Mt Biokovo Nature park:
If you continue by 512 a few hundred meter, after short tunnel you have to a beautiful view point:
Thank you very much!
After you climb the serpentines in Mt Biokovo Nature Park, there is the Vrata Biokova (Gates of Biokovo) restaurant with excellent lamb on a spin. Behind it, there is a WW II monument with sillhouetes of all islands carved in marble - using it you can actually recognise which islands you can see.
(notice that many pics are mine :-)
At this place, when driving towards the Sv. Jure (St. George) peak, you have a road leading few hundred meters to a mountaneer home "Vosac" (now closed, I think it's being reconstructed):
From there you can climb to Vosac peak with the old TV transmitter, from which you have a splendid view over Makarska:
it's actually the initial picture here - https://makarska-info.hr/en (check What to see at this page too)
