There's also the option of departing Cork-city centre to Cobh by taking an excursion on the River Lee on the passenger-tender Spirit of the Isles. Sailings depart the city's Penrose Quay, which is on the same side to the railway (Kent) station.

Sailings will operate this Saturday and Sunday and for the remaining weekends throughout September. The boat's Saturday schedule departs the city at 11am and arrives at Cobh's Kennedy Quay at 12.15pm.

In addition there is a Lower harbour tour off Cobh on Saturdays and Sundays, departing Kennedy Pier, Cobh - 12.30pm and returning to Kennedy Pier at 1.45pm. The boat then departs Cobh at 2pm to return to Cork with an arrival time of 3.15pm. For both this Saturday and Sunday sailing schedules, fares and further information go to www.corkharbourcruises.com

In the late 1980's the Spirit of the Isles then named Ingot operated excursions for several seasons from Dun Laoghaire's East Pier to Dalkey Sound and Killiney Bay.

Returning to the third annual Cork Harbour Open Day there will also be a free shuttle-service running in the lower harbour calling at Ringaskiddy, Monkstown, Cobh, Aghada and Crosshaven. The fast-ferry RIB operator 'Whale of a Time' is providing the free service which is sponsored by the Port of Cork Company and National Maritime College of Ireland (NMCI).
