I grew up over there and the coastal paths are pretty hairy at times – i rode around the South of the Island over Xmas and scared myself silly
The coastal path is called ‘The Way of the Gull’
I’m not sure if your allowed to ride the coastal path legally, but no one has ever given me a hard time when i’ve met them
I rode the coastal path about 17 years ago and it took us about 18 hours. There is one bit where the coastal path goes across a beach, so you need to get your timings right or they’ll be no path
The roads are relatively quiet, but why go on tarmac when you’ve got some of the best biking trails in the country there??
Enjoy!! 😆
