In this episode of Erin's Isle we meet a dentist from Drogheda who took a very long walk to school for three very good causes. Cormac McNamara knows how to make a difference.

We also meet Paul Doyle who runs Haper's Boutique B & B in Belfast. It's an amazing turn of the century guest house restored to Victorian splendor. It's a real look into what it takes to run a B&B in Ireland.

And we stroll through the Botanical Gardens at Queen's College.
