Every day when I commute to work I have the pleasure of taking this scenic railway line which spans between Greystones and Bray in Co Wicklow. The Bray Head Cliffs are not only beautiful to look at but is also great for bird watching.
You can see Shags/Cormorants and even Razorbills all along the waters edge and even the odd Seal lounging about on the rocks. The only downside is that it can be fairly tricky to get down to a safe area to view them.
The Cliffs also have a deep railway history and you can see evidence of its forgotten past such as the abandoned Brabazon Tunnel and the remains of the Brandy Hole viaduct.
