The operator will offer two new itineraries; a three-day cruise, which starts in Athens before sailing to Santorini and Mykonos, and a four-day itinerary, which will follow the same initial route but also take in Rhodes.
Michael Vinales, managing director of Olympic Holidays, said: "Following the successful launch and huge appetite we’re seeing for our island-hopping experiences, our two new cruise itineraries offer guests an alternative way to set sail and explore.
"With bespoke itineraries to accommodate varying requests around length of stay and budget, all guests have the option to extend their stay in Athens or add on another island or two."
Olympic offers a seven-night Cruise and Stay holiday from £1,415pp based on two people travelling.
