Quick Summary

Knocklayd is a mountain located in County Antrim, Northern Ireland, United Kingdom. It reaches an elevation of 1,695 feet. This region is characterized by the Antrim Mountains, an ancient basalt plateau with moorland and peat bogs, cut by deep valleys known as glens. These mountains tilt upward toward the coast, forming an impressive cliff coastline. Knocklayd is one of several prominent peaks in the Antrim area, alongside Trostan and Slieveanorra. The landscape of Northern Ireland is often described as a saucer centered on Lough Neagh, with highlands forming its rim.12
