Published on April 23, 2026 and written by Cyril Jarnias

Located at the western edge of Europe, the island of Ireland majestically spans approximately 84,421 square kilometers, offering a rich mosaic of varied and breathtaking landscapes.

Covered in lush green hills, fertile plains, and crisscrossed by a network of winding rivers, Ireland is often called the “Emerald Isle” due to its luxuriant greenery.

Bathed by the Atlantic Ocean to the west, it is sculpted by a multitude of spectacular cliffs, notably the Cliffs of Moher, and dotted with sparkling lakes like Lough Corrib.

This captivating island nation also reveals a fascinating geological history that includes karst formations in the Burren and imposing mountains such as the MacGillycuddy’s Reeks.

Add to this a mild yet unpredictable oceanic climate, and you get a picture of striking contrasts that continually attracts nature lovers and seekers of stunning panoramas.
