This is a really good walk with superb views of the Atlantic Ocean to the West and Smerwick Harbour to the East.
View SW from the Three Sisters to Sybil Head: Smerwick Harbour (L) and Atlantic (R)There are sections where the exposure is severe/thrilling/a hoot (delete as appropriate) and I would recommend saving it for a day with great visibility and as windless a day as possible.
On the day in question, I had 35-45 kph winds and gusts from the SE which meant I kept dropping down into the fields from the cliffs at several points!
