Past the beautiful town of Sozopol and the glorious sand dunes of Primorsko, we come to the most south-eastern corner of Bulgaria, covered by the forests of the Strandja mountain - an endless chain of mild crests and folding wood-covered tops. Small villages with their pastures, meadows and fields lie dispersed on the mountain slopes between the meanders of several picturesque rivers.

The Strandja occupies one of the first places  in Europe in terms of biological diversity. Its forests are representative of the typical temperate broad-leaved deciduous forest composed by Fagus orientalis, Quercus polycarpa and Quercus hartwissiana with laurel undergrowth, featuring the beautiful Rododendron ponticum.

Other botanical specialities in the Strandja would be the Verbascum bugilifolium, Cistus salvifolius, Cistis incanus, Iris sintenisii, Geranium asphodeloides, Daphne pontica, Epimedium pubigerum, Ilex colchica, Mespilus germanica, Pyracantha coccinea, Stachys thracica.

The Strandja provides shelter to the Booted Eagle, the Masked Shrike, the Olive-tree Warbler, the Semi-collared Flycatcher, etc.. The roadsides dazzle with Rollers, Bee-eaters, Hoopoes and Black-headed Buntings.

The ancient human civilizations have left a number of original cultural monuments in these lands: dolmens, Thracian sanctuaries and altars, burial tombs and necropolises, many chapels and other sacred places. The traditional Strandja architecture, preserved in many settlements is also interesting. The rich folklore traditions, the original rituals and habits of the local people, like the fire- dancing ritual practiced on St. Konstantine and Helen's Day, have preserved pagan elements from the remotest past.
