Nature

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.

Bulgaria, sadly, is small enough to provide any true dark sky location like Norway, Scotland or the American Southwest. Wherever you travel in the Bulgarian mountains or along the Black Sea coast you will never be sufficiently removed from a city or town to be able to see all of the stars twinkling in a genuinely "black" sky. However, with a bit of research you will be able to at least observe the seasonal meteorite showers over the northern hemisphere. And with the right approach you will capture fantastic images that will stun friends and families back home.

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.

The human penchant for spotting visual patterns in seemingly chaotic landscapes, preferring false positives to false negatives, has been crucial for survival. For thousands of years, the ones who lived long enough to pass their genes to the next generation were the ones able to spot the lion hidden in the bush. Even when there was no lion at all.

Several large rivers define Bulgaria's geography and historical landscape. The mighty Danube has constituted the northern border of the Bulgarian territories for centuries. The Iskar bypasses Sofia (locals still jokingly declare it to be the deepest river in the world) and then carves its way into the Stara Planina gorge, oft-described in the late-19th century Bulgarian literature. The Maritsa flows through the Thracian Plain: an ancient route used by generations of invaders, merchants, emissaries and empires. Today, the international route E80 runs along much of its course.

With the exception of some pockets of overdevelopment, the northern Bulgarian Black Sea coast remains a place of relatively unspoiled nature, picturesque beaches and cliffs, historical sites and landscapes to remember. It is the home of rare ecosystems, like the easternmost edges of the great Eurasian steppes. Its location on the Via Pontica migratory route is why in spring and autumn its skies are full with birds, many of them endangered species.

Bulgaria claims the highest waterfall in the Balkans, the 124.5-metre Rayskoto Praskalo, or Heavens' Sprinkler, in the Stara Planina mountains. In addition to it, this country has some famous waterfalls: in Boyana, just south of Sofia, the Borov Kamak near Vratsa and the Rilska Skakavitsa in the Rila, to name but a few. However, there are plenty of other less-known waterfalls waiting to be discovered. Finding them is a delight in the heat of summer, and you do not need to hike for hours to reach them.

However, as so often happens in Bulgaria, appearances are deceiving. Leave the main road and you will discover that the rolling hills hide intriguing natural phenomena.

The Krushuna Waterfalls is one of the best known. Located by the eponymous village, near the town of Letnitsa, the waterfalls started to attract visitors in the 2000s, when an eco trail was built around them.

The Krushuna Waterfalls is a cascade carved by the Proynovska River into the soft travertine rock, the largest formation of this sort in Bulgaria.

The old woman looks bewildered.

"Where is what?," she asks.

"Emen!" we repeat, raising our voices, as we now suspect that she is hard of hearing. "Where the waterfall is."

"A-a-ah! You mean Yemen!," the lady beams and then embarks on one of those elaborate explanations of directions that inhabitants in small-town Bulgaria are so prone to.

Go to Tyulenovo.

Even before the day trippers have started their descent to Byala Reka, or White River, their uneven melody precedes them. After a while the singers themselves appear, hikers whose tiredness testifies that they have seen much more than just the Byala Reka Eco-Path.

However, when travelling in this region, you should not forego the opportunity to peer into the dark, mysterious underground.

Magurata Cave, about 18km northwest of Belogradchik, is a place that takes you not only far from the sun, but also far back into the past.

Growing in fields that often look endless, they raise their large heads in rows, inspiring the traveller to stop and to release for a minute their inner Van Gogh: photos are taken, bouquets are made and brought home.

Sunflowers have covered Bulgaria for such a long time, and are so ubiquitous, that without them the countryside in early summer would look strange and bereft.

Sinemorets, one of the last Bulgarian villages before the border with Turkey, is one of those places.

The village has its fair share of ugly hotels destroying the view and the tranquility, but as it is far from the main hubs of tourist activities on the coast, these abominations are small in scale and leave enough space for true nature to survive, and for you to enjoy it.

It is easy to see why people gave such a name to the two stone arches spanning the small brook, and the series of caves near Vratsa. Even when you know in advance that the main stone arch is 20m high, 25m wide and 125m long, you only appreciate the magnitude of the place when you see it with your own eyes.

This corner of Bulgaria is a protected area where wildlife cohabits with ancient ruins, and the southernmost corner of the great Eurasian steppes reaches a rugged seacoast full of coves and caves. Located about a couple of kilometres from the nondescript village of Kamen Bryag, Yaylata remains one of the last refuges of nature, history and landscape undisturbed by human presence in Bulgaria. Most tourists come here to take photos, and then rush away to more comfortable places.

Through the 1970s and 1980s Alexander Ivanov was one of this country's most innovative photographers. He was the mastermind of the association of photographers in his native Kazanlak, and his experiments in colour photography at the time brought him prestigious national and international photography awards.

Since 1988 Alexander Ivanov has been a freelance photographer based in Kazanlak.

The first place of interest after Lakatnik might look strange to a foreigner: a five-metre statue of an old man apparently staring into the gorge, at Ochindol village. The 2005 monument represents one of the best known literary characters in Bulgaria, the Dyado, or Grandpa, Yotso from the short story Dyado Yotso is Looking On by Ivan Vazov. The story is about a blind octogenarian from an isolated hamlet in the Iskar Gorge who is fascinated by every single sign of Bulgaria's independence from the Ottomans; from the uniforms of an official and a soldier to the newly-built railway.

So far, more than 4,500 have been discovered and mapped. The number is so high because 22 percent of the country is covered with karst, a topography created when water soaks, dissolves and carves sedimentary rocks, mainly limestone, dolomite, and marble. Over millennia, the water shapes the karst into a variety of forms both on the ground and deep below. Caves are some of the most spectacular results of this activity.
