Short walk to decent views

I'll be honest; I had never heard of Knockbrack until it showed up near the tail end of my "Local 100" list. A little bit of research and I came across the fascinating fact that it may be the only place in Ireland that is visible from England. Full story here:

We visited Knockbrack on 5/11/2023. Parked at the recommended spot at the double gate O1526260153 starA. There's plenty of room to park off the road without blocking the gate. Up a path through the first field, taking a left option where the path splits off to the mobile phone mast. Over a gate into the second field which was planted with a young crop.

Keeping to the right edge of this field made for a very mucky and downright unpleasant walk up along a mucky ditch. Fine views opened up towards the coast, Lambay and Howth, but it was hard to appreciate them under the circumstances.

Finally arrived at the gap into the third field where the summit mound and trig point were just a short distance ahead. Beautiful views of the sea and islands to the east, the central plains to the west, Wicklow and the Mournes looking surprisingly close.

A short walk of less than 2 km return, 38 minutes including time at the top. Linkback:
