Ada Ciganlija-Smokvica is a freshwater training site on Belgrade's Sava Lake, near the Smokvica side of Ada Ciganlija. It is a shore-entry lake dive with a marked practice area used for guided drills and night work. That makes it a better fit for check-outs, buoyancy practice, and repeat training than for scenery-first diving. Summer bathing traffic can reduce clarity, while cooler months are usually the better window for cleaner water and steadier practice.
