Pula is quiet and safe. During the tourist season, however, the city is flooded with visitors, including, of course, those looking for easy money.
So keep valuables and jewelry in a hotel safe (from 20 NRK per day), don't carry money in the back pocket of your pants and bags on one shoulder when walking around the city, don't hang cameras and bags on the backs of chairs in cafes and restaurants, and don't leave things in the car.
The biggest dangers of the Croatian resort are related to the fauna of the Adriatic. Sea urchins may be waiting for you in the water, especially on "wild" beaches. The presence of these sea creatures indicates that the water area is impeccably clean. But a meeting with them may not end very pleasantly. Therefore, do not forget to bring special bathing slippers. If you still step on a hedgehog, dip your foot in hot water and treat the wound with antiseptic. The second danger of beaches is rocks formed by dead corals. It's easy to cut yourself on their sharp edges (slippers come to mind).
In Croatia's nature reserves and forests, don't stray too far from the hiking trails. There are poisonous vipers in the green thickets.
