Eirinikos Glassbottom Daily & Private Cruises operates from Ouranoupoli, Greece, offering glass-bottom boat excursions along the Mount Athos coast and surrounding Halkidiki islands. The company runs daily and private cruises aboard the Eirinikos glass-bottom vessel, providing passengers with above-water panoramas and direct views of underwater life through the vessel’s glass panels.
Trip options include the Back to 80's Disco Cruise from Ouranoupoli, a 2.5-hour evening cruise with nostalgic music, cocktails, visits to the Drenia islets, and illuminated seabed views at sunset; the Mount Athos Sightseeing Cruise, a three-hour journey showcasing the Holy Monasteries and Ouranoupoli’s reef; the Mount Athos & Ammouliani Island cruise, a five-hour trip featuring views of the Holy Monasteries and a 1.5-hour stop at Ammouliani for swimming or dining; and the Blue Lagoon - Vourvourou Lunch Cruise, a swimming and lunch cruise with two stops in crystal-clear waters and a barbecue lunch near Alikes beach.
Eirinikos focuses on combining natural scenery, cultural heritage, and marine observation in a single outing. The glass-bottom design allows families, women, and other travelers to observe underwater life without diving. Operations depart from Ouranoupoli and serve the proximate attractions of Mount Athos, Ammouliani, the Drenia islets, and Vourvourou. The company offers both scheduled daily sailings and private charters suitable for groups seeking customizable itineraries. Information, trip durations, and route details are published for each excursion, enabling travelers to choose cruises that match their interests and schedules.
