YACHT TRIP from St. PetersburgVlasa - this week we stand in the Dinevi marina and go out to sea for daytime walks every day. Those who wish to assemble a group or write to me personally and I will do this myself, and so write, call book an excellent boat Sun Odessey - 40, which will comfortably take you to the mussel farm, where the purest sea water is waiting for you to swim!
