If you're thinking of exploring the city and its sights on your own, the best way is to go for a walk.
You can walk to, say, the nearby town of Labin, which is home to many monuments. The two towns are connected by a pedestrian path, so it's an easy and even enjoyable walk around Rabac.
Tourist boat trips to the open sea are also popular in Rabac, as well as bicycle tours. Bike rental shops in Rabac are located both on the seafront and near the hotels.
