There is a little dive base with OK equipment (no computers, octopus poor, little free flow on valve) offering beach dives, which are probably not worth the effort, as visibility will be limited and the instruction is poor. If you have your certification though, and are confident that you can handle standard situations on your own, you can borrow equipment there, and go - together with the divemaster - to the shipwreck which lies about 150 m off shore from -10 to +5 m. The lifesavers on duty will row you there. The wreck should not be entered, but going around is quite an experience - for one dive - and you have better visibility there. As the Black Sea is not a prime dive area, you can not expect to see anything spectacular of course.
