If you’re starting from Cork City, you can easily walk to Rochestown through the old Cork City to Crosshaven railway line in less than an hour. There is the alternative path of walking around Mahon, past Blackrock castle, alongside the estuary and adding another 45 minutes to your journey rather than cutting through Mahon itself. I took this photo shortly before joining the old railway track again and continuing on down to Monkstown.
