The Strandzha

A group of barefoot men and women dancing in a large circle of live embers, while hypnotic music beats a rhythm that gets under your skin and into your blood: Firewalker dances in Bulgaria are a spectacular rite to watch. A tradition whose origins are lost in time, the nestinari dances almost disappeared in the 20th century, but were eventually revived, albeit modernised, to appeal to a modern audience hungry for Instagrammable and TikTokable "authentic" experiences.

Bulgaria has its fair share of intriguing caves, from the Devil's Throat underground waterfall to Prohodna's eyes-like openings and the Magura's prehistoric rock art. One of the most interesting of these, however, would not be of much interest to a caver as it is neither large, nor deep or covered in stalactites. This cave is interesting for its role as a sacred place in the lives of generations of people, as well as its remoteness on the Bulgarian-Turkish border.

Men dressed in early 20th century military uniforms, patriotic songs and speeches, lots of banners and grilled meat stalls: if you crave attending a mass event after the end of the Covid-19 travel restrictions, consider visiting Petrova Niva in the third weekend of August.

Marked with a sombre stone monument at a picturesque bend of the Veleka river, Petrova Niva is connected to a heroic and traumatic event in Bulgarian history, the St Elijah-Transfiguration Uprising.

The Strandzha mountains coast, roughly everything along the Black Sea south of Burgas, is about 100 km long as the crow flies. Yet it is very varied. You will discover smaller and bigger bays, old towns and purpose-built modern resorts, a campsite or two, a number of picturesque rivers, inlets and... islands. In fact all of Bulgaria's islands are along the Strandzha coast. You will probably be underwhelmed, however. There are just four of them, not counting the St Kirik Isle north of Sozopol which was appended to the mainland, in the 20th century, with a quay.

Much has been said and written about the beauties of Bulgarian nature and the abundance of its wildlife. Birdwatching, for example, has become a mainstream tourism activity that many travel agents organise for Western visitors. Yet little if anything has been promulgated about another remarkable if not so obvious (for obvious reasons, pun unintended) treasure that Bulgarian forests, meadows and riversides have: the abundance of fireflies.

"I dislike bringing people here." The voice of the guide from the tourist office in Malko Tarnovo drops, as we approach the summit of Golyamo Gradishte, the highest peak in the Bulgarian part of the Strandzha mountains. It is summer. The sun shines through the thick foliage of the oak forest. The only thing negative about this pristine location, in the Strandzha Nature Park, are the midges that swarm around our eyes.

The importance of a plant species can vary according to the ecosystem it is part of. A beautiful plant that grows in a very limited area in Bulgaria is a case in point.

In the past two centuries, geography, politics and moments of national triumph and tragedy have defined the borders of Bulgaria. The current territory of the Bulgarian nation appeared after the Berlin Congress in 1879, stretched and contracted during and after several wars in 1885-1886, 1912-1913 and 1915-1918, and peacefully set into its current shape in 1940.

Kapka Kassabova was born and raised in Bulgaria, spent her late teens and twenties in New Zealand and now lives in the Scottish Highlands. She started writing poetry as a schoolgirl, but turned to fiction and non-fiction many years ago – in English, her adopted language. Her narrative non-fiction books, including Street Without a Name and Twelve Minutes of Love, as well as novels such as Villa Pacifica have earned her an international reputation as being one of the freshest literary voices of her generation.
