Dadia – Lefkimi – Soufli
Pine and oak hills above the Evros in Greece's far north-east — thirty-six of Europe's thirty-eight diurnal raptor species have been recorded here, including the Balkans' only surviving black vulture colony.
The Εθνικό Πάρκο Δάσους Δαδιάς – Λευκίμης – Σουφλίου covers four hundred and twenty-eight square kilometres of low forested hills in the Evros regional unit, the last corner of Greece before Turkey, and it exists for one reason: birds of prey. Thirty-six of the thirty-eight diurnal raptor species recorded in Europe occur here, a concentration no other single site on the continent matches. Protection began in 1980 with two strict core zones totalling seventy-two point nine square kilometres; the national park proper, with its wider buffer, was declared by joint ministerial decision 35633 of 30 August 2006, published in gazette issue 911/D. It is managed as IUCN category VI, sits in the Natura 2000 network, and went onto Greece's UNESCO tentative list in 2014 under criterion x — the biodiversity criterion, not a scenic one.
The park lies at the south-eastern end of the Rhodope massif, and the ground reflects it: Tertiary volcanic and sedimentary rocks across the south, ophiolite complexes in the north, weathered into rolling hills rather than mountains. Mount Kapsalo, the high point, reaches only six hundred and twenty metres, and the marked red trail from the village climbs to a viewpoint at Gibrena at five hundred and twenty. That modest relief is part of the point. Calabrian and black pine hold the central and eastern hills, oak — Quercus frainetto, Q. cerris, Q. pubescens — the north and south-west, and between the stands lies a worn-in patchwork of grazing land, streambeds and small cultivated plots. Raptors need two things that rarely sit close together: undisturbed mature trees to nest in, and open ground to hunt over. Dadia keeps them a few hundred metres apart. The free-ranging livestock on that open ground supplies carrion, which is why the decline of traditional herding counts as a conservation threat here rather than a pastoral footnote. Rainfall averages around seven hundred and thirty millimetres a year, with cold winters and hot dry summers.
Three of Europe's four vulture species breed in the park. The griffon stopped nesting in 1995 and returned in 2007, when three pairs took up the traditional breeding rocks again; the Egyptian vulture has slipped from eight to ten pairs to four or five, which still makes Dadia the species' stronghold in Greece. The one that matters most is the cinereous, or black, vulture — Aegypius monachus — which nests not on cliffs but in the flat crowns of old pines, and whose Dadia population is the only naturally surviving colony left in the Balkans, every other having gone during the twentieth century. It came close to going too: twenty-five birds in 1985. A supplementary feeding programme began in 1987 and still runs weekly, year-round; WWF Greece put a permanent field unit on the ground in 1992; by 2002 the population was back to around a hundred.
Then, in August 2023, the fire that began near Alexandroupoli burned some seventy-three thousand hectares — the largest single wildfire recorded in the European Union — and took more than half the park with it, including much of the old pine the vultures nested in. Since then, staff have been bolting wooden platforms into the young regrowth, because a tree that has had two years to grow cannot carry a black vulture's nest, which can reach three metres across. The first chicks hatched in those artificial nests in 2026. The colony did not leave: thirty-six pairs before the fire, a record forty-seven in 2025, forty-four in 2026. Soufli, the third name on the sign, is a separate kind of survival — a silk town whose population peaked around 1908 at some twelve thousand on the strength of mulberry groves and cocoon rearing, and whose tall shuttered koukoulospita now house a silk museum instead of silkworms.
What's worth knowing before you go
The gateway is Alexandroupoli, which has an airport and is the hub for KTEL Evrou buses up the Evros valley; they run to Soufli roughly hourly. Dadia village is sixty-five kilometres north of the city, about an hour by car, and a short taxi ride from Soufli if you are not driving. The information centre in the village opens daily from eight to four — closed only on 1 January, Easter Sunday and Christmas Day — and runs a fifteen-seat minibus to the raptor observatory two kilometres away at 8.30, 10.00, 11.30 and 13.00. It fills, so book. Waymarked trails leave from the centre, including the red route up Gibrena, about two and a half hours at a moderate grade. Come in spring, when the migrants are back and the ground is green. Late summer is hot, hazy and unrewarding for anything that soars, and it is also the season the fires come; winter is cold but concentrates vultures at the feeding site, when carrion is scarcest elsewhere.
The detail worth acting on is the time of the first minibus. Vultures cannot soar until the ground has warmed enough to throw up thermals, so at half past eight the birds are still perched or beating low across the ridge — close enough to separate a black vulture, uniformly dark with a wedge-shaped tail, from a griffon's sandy plumage, white ruff and short square tail with the naked eye. By mid-morning they are a thousand metres up and both are specks. Ask at the centre which day of the week the feeding site is stocked, and go on that one.
