A ruined Napoleonic-era signal tower perched on Hag's Head at the southern tip of the Cliffs of Moher — the free, crowd-free way to experience Ireland's most famous cliffs, with panoramic views south to Loop Head and north along the full sweep of the 8 km cliff line.
This square stone ruin, built around 1808, stands on the site of the ancient promontory fort Mothar — the fortification that gave the Cliffs of Moher their name. The roofless tower still has visible fireplaces and bartizans (corner turrets), and in summer it hosts nesting choughs. You can walk right up to and inside the ruin.
From the tower, look north and you'll see the entire 8 km sweep of the Cliffs of Moher stretching towards O'Brien's Tower and beyond to Doolin. On a clear day the Aran Islands, Galway Bay, the Twelve Pins and Maum Turk mountains in Connemara are all visible.
From Liscannor village, it's roughly a 1 km walk out to Moher Tower along a gravel road. The approach gives you building anticipation as the tower and cliffs reveal themselves. About 15–20 minutes on foot from the trailhead. Note: the cliff-edge path north to the Visitor Centre has been closed since August 2024 for safety works.
Walk around the point to catch the rock formation that resembles a woman's head staring out to sea — the 'witch' Mal of local legend, who supposedly chased the hero Cú Chulainn and fell to her death here. There's also a natural sea arch carved into the headland.
The light comes from the west, straight onto the cliff faces, turning the rock golden. With no visitor-centre crowds, you'll likely have the headland almost to yourself — a genuinely magical end to the day.
