There is a song written by Rikard Katalinić Jeretov in 1940. About the beautiful pebble beach Sipar in Mošćenilka Draga.
The sand of Sipar beach has been deposited for centuries from the sand of the Draga stream that springs on the slopes of the Učka mountain, and the pebbles of Sipar are formed by sea waves. Its white, clean and smooth pebbles, crystal clear sea entices you to cool off on the beach and relax on hot summer days. The locals call these stone/pebble "sipar".
Draga is a valley open to the sea by the Sutjeska, a narrow area between Solin and Vežica, after which Draga got its name. The most important role in the creation of this gorge was played by Draga stream and its impact on the flysch and limestone soils of the valley bordered by carbonate rocks and deposits. This composition of the soil made it possible to maintain Draga stream, which along with Rječina is the only permanent watercourse in the area of the city of Rijeka.
Due to numerous sources of drinking water (Javor, Vrulja, Vrutak, Jamica and Grmlje), lush vegetation and the picturesque watercourse of Draga stream, Draga has always been attractive location for living and in the past was one of the most populated places in this area.
The canyons of Mošćenička Draga, Medveja and Ika are the three largest and deepest cut canyons formed on the eastern slopes of the Učka mountain. These streams are dry for a good part of the year and larger amounts of water occur in periods with heavy rains or when the snow on Učka melts abruptly, which is why we call such streams torrential.
Draga stream is a deeply incised valley that stretches from its source in the Valbat area below the Učka and Suhi vrh massifs in a southwest-northeast direction and flows into the sea in Mošćenička Draga, creating one of the largest and most beautiful beaches on the northern Adriatic, Sipar beach.
