Most of the attractions on this itinerary are located in the center of Cork city and can be reached on foot from your hotel. If you're planning to visit Blarney Castle, you can take a bus from the city center which will take approximately 30-45 minutes and costs around $7.
If you have more time, consider a walk along the River Lee or a visit to the Cork City Gaol for a glimpse of Cork's dark past. If you have less time, you may want to skip the Kerrygold Experience or the Oliver Plunkett Street and spend more time at the other attractions.
