Piski – The Istrian Desert

An unexpected landscape in the Heart of Istria

Imagine stumbling upon a landscape that feels like another world, not in some far-flung corner of the globe, but nestled within the familiar beauty of Europe. Croatia, often envisioned with its sun-drenched coastlines and ancient walled cities, holds a secret inland – a place known as Piski, or Kalanki, often referred to as the Istrian Desert. This isn’t your typical sandy expanse, but a unique natural phenomenon that offers a surprising and captivating experience for those who venture to discover it. Amidst the picturesque Istrian scenery lies Piski, a testament to the diverse and sometimes surprising natural wonders that Croatia holds. This intriguing location, also called the Šterna desert or Calanchi di Sterna, is situated in the eastern part of Upper Bujština. What makes Piski so remarkable is its composition: it’s not a traditional desert of sand dunes, but rather a wavy, barren area formed from marl, a fine-grained sedimentary rock with a distinctive gray-blue hue, known locally as tašelac or tašel.

The Marl “Dunes”

The landscape of Piski visually resembles a small desert with its undulating “dunes” stretching across more than 10 hectares, with the largest section located west of Šterna. While seemingly an anomaly in the verdant Istrian landscape, such marl formations, locally called “peski,” are not entirely uncommon in the central and northern parts of the peninsula. However, the concentration of these formations in one area is what truly distinguishes Piski. This prevalence of marl also explains why the central region of Istria is often referred to as Gray Istria. Evidence of this geological influence extends to other nearby locations, such as the areas around Hum and below Roč. Even the name of the Piskovica cave near Gologorica, the longest cave in Croatia formed in flysch, hints at the impact of this “pisak” (sand/marl) on the surrounding terrain.

A Budding Tourist Attraction with Future Thrills

The Istrian Desert, or Piski, stands out as a remarkable natural phenomenon in Croatia, captivating visitors with its otherworldly appearance that evokes the feeling of walking on another planet. Over time, this unique landscape has naturally drawn the attention of those seeking unusual and intriguing sights, gradually establishing itself as a noteworthy tourist attraction. The very name “desert” piques curiosity, enticing visitors to explore this unexpected terrain and witness its stark beauty firsthand. Looking ahead, Piski is poised to offer an even more thrilling experience with additions such as a zip line. This feature is also considered a responsible approach to tourism, providing an alternative for experiencing the area without directly impacting the delicate marl formations. The Istrian Desert presents an opportunity to witness a geological wonder that challenges typical European expectations, solidifying its place as a truly remarkable destination to explore.
