Romania's Black Sea Coast is defined by wreck diving. The majority of sites are sunken vessels spread across three sub-areas: Constanța holds the largest concentration, while Mangalia and Eforie & Costinești add pier and reef options closer inshore. Skill levels span beginner to advanced technical, with deep offshore wrecks such as the Moskva Destroyer Wreck and Sc-213 demanding experience, and shallow shore entries like Mangalia Pier suiting newer divers. Water temperatures peak in late summer, making June through September the most comfortable window. Sea Anemone and Common Moon Jellyfish are among the observed species across these sites.

Water temperatures follow a clear seasonal curve, rising from cold winter lows to their warmest in late summer, with September often the peak month. The best diving window runs from June through September, when conditions are most comfortable and the widest range of sites is accessible. Outside this window, cooler temperatures and reduced visibility favour experienced cold-water divers rather than casual visitors.

Across Black Sea Coast's dive sites, June, July, August and September are most often reported as the best months to visit.
Observed species include Sea Anemone, Common Moon Jellyfish, Barrel Jellyfish, and Striped Red Mullet. Sea Anemone is recorded as very common across sites. Jellyfish encounters are occasional, so divers should remain aware of their surroundings, particularly in open water.
Several sites are rated beginner level, including Mangalia Pier, Mangalia Pier 2, Cazino Constanta, and Eforie, all accessible from shore and reaching only shallow depths. The majority of the region's wrecks, however, sit at intermediate to advanced depths and require boat access, so less experienced divers should focus on the inshore options first.
Constanța has the largest number of sites and includes both deep offshore wrecks and the shore-entry Cazino Constanta archaeological site. Mangalia is centred on pier and artificial reef diving, well suited to beginners. Eforie & Costinești offers a small number of sites and rounds out the region's shallower, shore-accessible options.
There are numerous operators active in the region, including ScubaDiver.ro, Nemo Diving Center, Aqua Mar Team, Marine Explorers Dive Center, Scuba Academy, Nautilius-Diving, and Ion Buncea's Diving School, among others. Most concentrate their services around Constanța, which is the logistical hub for boat-based wreck diving.
