The bay is not a true fjord because it was formed by the erosion of the Pazinčica River, not glacial activity.
The brackish water makes the bay an ideal environment for commercial mussel and oyster farming.
Romualdo's Cave, located near the top of the canyon, was inhabited by St. Romuald in the 11th century.
The bay serves as a natural boundary separating the regions of Poreč and Rovinj.
The water temperature in the bay is typically lower than the surrounding Adriatic Sea due to numerous submarine freshwater springs.
Archaeological excavations have uncovered remains from the Neolithic, Bronze, and Iron Ages within the bay's vicinity.
The canyon walls are a popular site for sport climbing, though activities are restricted to protect local nesting birds.
Lim Bay, often referred to as Lim Fjord, is a 10-kilometer-long submerged karst valley canyon located on the western coast of the Istrian peninsula. Despite its name, it is a ria—a drowned river valley—rather than a true glacial fjord. The canyon walls rise up to 100 meters above sea level and are covered in dense Mediterranean maquis vegetation. The brackish water composition, resulting from the mixture of sea water and subterranean freshwater springs, creates a unique ecosystem ideal for bivalve cultivation. It serves as a protected marine reserve and a geomorphological site of scientific interest. The area is part of a larger protected landscape extending between the towns of Vrsar and Rovinj. Historic remnants, including the Romualdo's Cave, are situated on the northern side of the bay. The site is a significant habitat for various bird species and protected flora.

Bring binoculars to observe the nesting birds on the high canyon cliffs.
The most comprehensive views are found from the designated lookout points on the northern road approach.
Wear sturdy footwear if planning to hike the trails leading toward the cave entrance.
Do not attempt to swim or moor boats in areas explicitly marked as protected zones for mussel farming.
Boat tours operate primarily from spring through early autumn; cave access is often restricted outside of guided tour seasons.
Maintain silence near the cliff sides to avoid disturbing local wildlife; observe all posted signs regarding protected cave access.
