Avoid this road unless you have a light racing bike and are called Tadej Pogacar. Gradient gets up to 17%. Great view though!

An old-fashioned marina in a fishing village. An idyllic place to stop during the long walk on this stretch of the CCR.

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.
