Ayu-dag offers a combination of reef and cave diving along the Southern Coast of Ukraine. Divers can explore depths between 15 and 25 metres, where visibility typically ranges from 10 to 20 metres. The site is characterised by moderate currents and distinct thermoclines, with water temperatures fluctuating between 9C and 16C. Due to these conditions, a 7mm wetsuit or drysuit is recommended. Access to the site is by boat only. Divers should remain vigilant regarding boat traffic during ascents and safety stops. The reef and cave systems support a variety of regional marine life, including invertebrates and reef fish.

The Black Sea Coast Wreck in the Sevastopol Area offers a varied underwater landscape featuring a combination of natural reef, wreck, and artificial reef structures. Spanning depths from 5 to 30 metres, the site is suited for intermediate divers. Shore entry requires careful timing due to surf conditions. Divers should be prepared for cold water temperatures ranging from 9 to 15 degrees Celsius, with thermoclines common throughout the water column. Visibility is highly variable, fluctuating between 2 and 15 metres. Due to the potential for entanglement within the wreck structure and changing visibility, maintaining close proximity to your dive team is essential. A drysuit or thick wetsuit with a hood is recommended.
