Leave Niš around 08:00, taking the E80/A1 toward Prokuplje and then Route 35 toward Kuršumlija and Prolom Banja. The drive to the spa is usually about 1 hour 45 minutes to 2 hours, but go first to Đavolja Varoš, allowing roughly another 30–40 minutes from Prolom Banja. Roads become narrower and more winding near the site, so fill up in Niš or Kuršumlija and carry some cash. At Đavolja Varoš, expect around two hours for the visitor area and marked forest paths; the earth pyramids are best in the cooler morning, and sturdy shoes are worthwhile. Entry is generally modest—roughly €3–5, though seasonal prices can change—and the site typically operates from morning through late afternoon in summer.
Return to the spa complex for a relaxed lunch at Prolom Banja Restaurant, where regional dishes such as grilled meat, soups, kajmak, and seasonal salads make sense after the walk. Allow about an hour and budget approximately €8–15 per person. Then spend two to three unhurried hours at the Prolom Banja Spa & Wellness Centre: use the thermal pools and sauna facilities, and book any massage or treatment in advance if possible. Spa access is commonly around €10–20, while treatments may bring the total closer to €35; confirm the day’s timetable and pool-only admission at reception, as hours can vary.
After the spa, sample the mineral water at the Prolom mineral-water spring and follow the easy park paths into the surrounding greenery. This is a gentle, pleasantly quiet hour rather than a major hike, so keep it slow and bring a refillable bottle. Walk or drive back to your accommodation in the central spa area in about 15 minutes, then leave the car parked and have a restful dinner nearby. If returning to Niš the same day, depart by about 18:00 via Route 35 toward Prokuplje and the A1/E80; allow roughly two hours, with the final stretch easiest in daylight.
