They sound like something out of Game of Thrones but VIVA the Danube’s Iron Gates are all too real and more dramatic than anything in George RR Martin’s world.
An 83-mile route, with the last barrier, the Kazan (Great Boiler) gorge being the narrowest and most breathtaking at just 15om just beyond the Romanian city of Orsova.
The side of the gorge in Romania constitutes the Iron Gates Natural Park, and the Serbian Đerdap National Park.
And what’s more Lepenski Vir in Serbia in the gorge and on the banks of the Danube is mooted as being the oldest planned settlement in Europe at 13,000 years ago.
Long before we’d hazard those Starks and their dragons were around.
Move aside Winterfell

Now all this will naturally pull in any of us who have enjoyed the charms of the Danube.
And even more so with VIVA Cruises tempting us with a gentle amble through its waters.
The 11-night ‘The Danube’s Iron Gates’, sailing on VIVA TWO departs Passau on September 6.
With ports of call including Bratislava, Belgrade, Donji Milanovac, Novi Sad and an overnight in Ilok.
Many of those stop-offs sounding like they’ve come straight out of Winterfell.
