Cliffs of Moher, Ireland

The Cliffs of Moher are one of Ireland’s most lauded sights, drawing tourists to drink in the dramatic scenery, enjoy the abundant birdlife and peer across to the rocky Aran Islands on a clear day. The cliffs’ weathered expanse unfolds for five miles (8km), reaching more than 700 feet (213m) at its highest point.

But with great height comes great danger and the clifftop’s dramatic brink has caught explorers off guard before. More than 60 accidental deaths have occurred here since the early 1990s, including a student falling to his death in 2019 after taking selfies near the cliff's edge. Portions of the cliff are also liable to collapse, so it’s wise to heed those signs urging you to stay back.
