Bring a valid ID every day, even if you already have your ticket or wristband. Security checks are standard, and entry procedures can be stricter than some visitors expect. Wear comfortable shoes with good grip: the fortress is beautiful, but it is also uneven, with stone surfaces, stairs, and long walking routes between stages.
July in Serbia is hot, with daytime temperatures often above 30°C, but nights can feel cooler on the fortress, especially after several hours outdoors. A light layer is useful after midnight. During the day, pace yourself: hydrate, eat properly, and avoid spending too long in direct sun before a full night at the festival.
Cashless systems are common inside the festival, but in the city it is still helpful to carry some Serbian dinars for kiosks, bakeries, or small purchases. Card payment is widespread in Novi Sad, though not universal. Mobile internet is generally reliable, but download maps, tickets, and key addresses in advance in case the network slows under heavy festival demand.
