In the heart of the municipality of Sveta Nedelja, there is a unique hiking trail that runs through a fascinating area of ??marl dunes. This route offers a unique experience where nature and history merge, giving nature lovers the opportunity to explore rare geological phenomena and enjoy the untouched landscape.
Marl dunes, formed by the erosion of a specific sedimentary rock known as marl, make this area special. These natural forms can rarely be seen in such a pronounced form, which makes them a real attraction for all those who want to experience something different from the typical karst phenomena prevalent in Istria. Unlike classic sand dunes, which are usually formed from fine sand in desert or coastal areas, marl dunes are formed from fine particles of marl. Due to its specific mineral composition, marl has unique properties – it is soft and easily worn down by weather conditions, but at the same time retains the strength that allows it to create stable shapes. The erosion process here works in such a way that it creates structures that resemble dunes, although they are much harder and more stable than sand dunes. Their beauty lies in the unusual, almost abstract forms they create in the landscape. Combined with the natural environment, they provide a unique experience for all visitors who love nature and exploration.
This phenomenon is not only geologically significant, but also aesthetically appealing. The undulating formations that erosion creates look almost like sculptures shaped by nature, which contributes to a sense of peace and connection with the environment. Marl dunes also play an important role in the ecosystem, as they support specific plant species that have adapted to this type of soil.
These dunes are a testament to the long-term and constant work of natural forces, which have shaped the landscape over millennia. As a natural phenomenon, they are an invaluable geological treasure that offers insight into the dynamics of the earth's surface and the process of soil formation. For all those who want to better understand nature and enjoy its charms, marl dunes provide an extraordinary experience.
The local population, especially those living near the dunes, has adapted their way of life to the natural environment. As marl dunes are sensitive to erosion and climate change, the locals have learned how to manage the land around them, taking care not to disturb the natural balance. This includes controlling grazing, agricultural activities and protecting vegetation that helps stabilize the soil.
This trail also offers a visit to two sacred buildings. The cemetery houses the church of St. Quirinus from the 16th century. The most important church in Šumberšćina is the church of the Blessed Virgin Mary of Dren, to which the biggest local holiday Petangošt is linked. The church has preserved one of the oldest and most valuable books of the Labin region, a lectionary of church songs from the early 18th century, popularly known as Šćavet; it contains a recording of the song V see vrime godischa.
The trail is ideal for hikers, recreationalists, but also families looking for an easier trip into nature. A walk along this path provides an opportunity to get acquainted with interesting relief forms, where marl has been shaped over time, under the influence of wind and water, into formations that resemble dunes. In addition to geological features, the trail also offers beautiful views, forest areas, and rich flora and fauna.
