Pazin Zip Line. The Pazinčica River flows through a canyon in Pazin, formed by land erosion millions of years ago. The zip line crosses the canyon twice, offering spectacular views and is also suitable for adventurous families, as children can make the crossing in tandem with a climbing equestrian. 100 meters below the surface, at the bottom of the canyon, lies a cave called "Pazin Cave," which can be explored with a guide. Part of the water flows through this cave and forms it. During rainy seasons, the canyon can fill with 80 meters of water.

At the foot of the northern ramparts of Pazin Castle there is an extremely valuable sequence of residential buildings in the late Gothic and Renaissance styles. These were the houses of the officials of the Pazin and Istria County who performed their duties within the castle itself, and therefore these buildings should be considered an integral part of Pazin Castle and treated accordingly. These buildings were built within the former walled suburb of the castle, and the remains of the ramparts are hidden within the structures of the eastern row of buildings. The architectural elements visible today were mostly built in the 16th century, but closer analysis would certainly reveal older structures given the earlier construction of the suburban ramparts. Some of the buildings were also rebuilt several times in later centuries.

The fort houses a local museum with 4 permanent exhibitions. Some descriptions are also in German. The entrance fee of €3.32 per adult can only be paid in cash. One may have doubts as to whether this is justified.

. The inhabitants of Pazin had great independence and freedom for that time, which made them very different from their neighbors, the serfs. In the 17th century the Marquis Montecuccoli of Modena bought the castle, which owned it until the mid-19th century. Having been used for more than a thousand years, the building has constantly changed its appearance; for example, the semicircular tower was added after 1463. In the literature, the first fortress was described as a long, two-storey building with a tower and a small church with a belfry next to it. Over time, the castle developed into a mighty walled fortress, which various owners expanded and rebuilt throughout the Middle Ages and modern times. Below its walls, which were accessed by a drawbridge, yawns the abyss of the Pazin Gorge;

In any case, the sanctuary of the parish church of St. Nikola in Pazin, which is decorated with frescoes. The Pazin Castle is a well-protected fortress on the cliff of the Pazinčica River Canyon, and it is also the largest and best-preserved medieval fortress in Istria. It was first mentioned in 983 in Emperor Otto II's deed of donation, in which he donated the castle to the Bishop of Poreč. The castle changed hands many times over the next two hundred years, to come into their possession by the marriage of the daughter of Menhard of Schwarzenburg to a member of the noble family of Gorica by 1374. In the same year it was taken over by the Habsburgs, and behind its mighty walls they ruled over the whole area of central Istria, or the County of Pazin; The castle proved its strength and power by not falling victim to the conquest in the war with Venice.
