Legend has it that this was the first known Irish home of Saint Patrick. The Mountain juts out of the surrounding plain, and is visible for miles around. The dramatic Slemish is actually the central core of a long extinct volcano. The legend goes that following his capture and being brought as a slave to Ireland, St Patrick worked as a shepherd at Slemish Mountain for about six years.

Affectionately known as ‘The Pencil’ The granite tower was built in 1887 as a memorial to James Chaine, the Harbour's developer. It's an accurate replica of an Irish Round Tower and was converted into a lighthouse by the Commissioners of Irish Lights in 1899. Has stood like a sentinel over the Lough ever since.

Wonderfully expansive forest and the lovely Glenwhirry river as a bonus. Apparently this place is well known for having been haunted by an ancient apparition! Always the same four Druids appear. To observe, then vanish.

The Queen of the Antrim Glens. Part of the Glenariff Glen has been designated as a National Nature Reserve. The timber boardwalk that winds through the glen and alongside the river gorge was first built about 100 years ago and has been carefully reconstructed to provide one of several spectacular walks. These include Rainbow Trail, Scenic Trail, Viewpoint Trail, and Waterfall Walk Trail...Yes there's a lovely Waterfall.

If you cycle along the beautiful coast road you will inevitably come through Carnlough. Carnlough Harbor is also central to the filming of Game of Thrones. On the screen, it turned into the free city of Braavos.
