Romania, land of eerie mountains and Vlad the Impaler 鈥� or so the stereotypes say. But the southeast of the country cradles a pristine wilderness of wetlands, forests and rocky steppe. As you bat away emperor dragonflies bigger than your hand, or watch tortoises lumber past to a deafening chorus of croaking frogs, you鈥檇 be forgiven for mistaking your surroundings for a tropical rainforest.

In this nature reserve unlike anywhere else in Europe, there鈥檚 only one impaler you鈥檒l hear about 鈥� and that鈥檚 the shrike, a bird that skewers insects on thorns.

Welcome to the Black Sea Borneo

This is the place where the Danube River completes its 2850km-long meander from Germany鈥檚 Black Forest through 10 European countries, ending in the Black Sea. A patchwork of habitats, from reed beds and marshes to forests and rocky steppe, nurture an astonishing range of wildlife.

搁辞尘补苍颈补鈥檚 is pinched between Ukraine to the north and Bulgaria in the south. Dobrogea, the region hugging the coast and , is something of a Borneo by the Balkans. The biosphere reserve, whose wetlands melt into the yawning Black Sea, is home to 300-plus bird species, more than half of which breed here.

Even non-twitchers can appreciate Dobrogea鈥檚 colourful birdlife: bee-eaters volley from cliffside nesting places in a flash of powder blue and peach, while a glimpse of green gives away the bright European roller. Inland, birds of prey circle Dobrogea鈥檚 rocky steppe. Just south in Babadag, wildflower meadows and forests unfurl, inhabited by tortoises and 2m-long whipsnakes.

Cruising the Danube Delta

Bird migrations bring impressive feeding frenzies to the delta. From June to mid-September, white pelicans arrive in huge numbers; winter brings almost the entire global population of red-breasted geese to careen around the reserve鈥檚 teal waters.

The large ships that sometimes thunder through the delta send wildlife fleeing. But on a small boat it鈥檚 possible to glide close to flocks of birds, as well as enter narrower channels where the atmosphere is most enchanting.

Along the channels snaking around the delta, ash branches sag into the water. Dragonflies alight in dozens on vast tree roots gnarling the riverbanks. Rays of sunlight pierce the leaves, spotlighting shy ibis.

When a boat snaps off its engine to sidle towards the wildlife, only the rush of water and cooing bullfinch break the silence.

Nature hikes from forest to steppe

Back on dry land, Dobrogea鈥檚 forests and rocky steppe also teem with natural beauty 鈥� if you know where to look.

South of Tulcea lies Babadag and its forest of ash and lime trees. Beneath the shade, wildlife guide Daniel Petrescu is holding up his hand for quiet. There鈥檚 a rapid trill floating in the air. 鈥楢n icterine warbler鈥�, he nods. 鈥極ne of the greatest singers of this forest.鈥�

For more than 20 years, wildlife expert Daniel has been leading boat tours and nature walks around Dobrogea. In the time it takes the rest of our group to fumble for binoculars, Daniel has described the species, imitated its mating call and zoomed in with a super-strength telescope.

There鈥檚 much to observe. Within this glade, tortoises laze in long grass and rare orchids burst from the ground. There鈥檚 birdsong and a staccato of woodpeckers.

Northwest of Babadag, we trail across rocky steppe, the M膬cin Mountains grumbling above us. Ground squirrels scamper across the arid land, with birds of prey in pursuit. Red-footed falcons are found in entire flocks here, while the white-tailed eagle 鈥� Europe鈥檚 largest 鈥� creates an impressive silhouette. Passing shepherds regard our merry band of birdwatchers with some bemusement.

Where nature meets Soviet history

Skeletons of industrial buildings are a peculiar setting for a nature reserve. But some of the region鈥檚 Soviet-era factories, empty and overgrown since the 1989 revolution, overlook ravishing natural sights. Brutalist architecture and natural beauty are strangely in sync.

At Caraorman in the centre of the biosphere reserve, sandpipers strut in the shadow of an old factory. Just before the Romanian revolution overthrew communist rule, this was destined to process glass, fuelled by a nearby sand dune. After everything of value was torn away, wildlife began to encroach into its very walls. Creepers thread the derelict buildings. Rusty shacks along the waterfront are now the backdrop to long-legged spoonbills feeding in the marshes.

The same is true in Vadu, south of Dobrogea near the Black Sea shore. At the Soviet factory here, buzzards perch on concrete columns and smashed windows are passageways for somersaulting larks.

At first it鈥檚 surreal to see flowers soften the edges of scaffolds, with farmers herding cattle in the surrounds. But after a while, foraging sandpipers and swarms of butterflies seem like the most fitting inhabitants for this lonely, beautiful place.
