Overview
Perched on the western edge of the Burren in County Clare, the Cliffs of Moher stretch for about 13 km along the Atlantic coastline. At their highest point, just north of O’Brien’s Tower, the limestone face rises 214 m (702 ft) above the sea, offering sweeping views of the Aran Islands, Galway Bay, the Maumturks, the Twelve Pins and, on clear days, the Loop Head peninsula. The southernmost promontory, known as Hag’s Head, forms the striking “witch’s head” silhouette and drops 120 m (394 ft) to the ocean, providing an immediate sense of height before the cliffs continue northwards.
History & Background
The name Moher comes from the ancient promontory fort Mothar that once stood on Hag’s Head; the fort was demolished in 1808 to supply stone for a Napoleonic‑era signal tower, later called Moher Tower. In 1835 Sir Cornelius O’Brien erected the round stone O’Brien’s Tower as an observation point for early tourists. The cliffs themselves are composed of Upper Carboniferous shale and sandstone laid down around 320 million years ago, later sculpted by relentless Atlantic wave action into the dramatic vertical faces seen today.
In the 1990s Clare County Council commissioned the purpose‑built Cliffs of Moher Visitor Experience, which opened in February 2007 after a €32 million investment. The eco‑friendly centre uses geothermal heating, solar panels and grey‑water recycling and houses interactive exhibits on geology, flora, fauna and human history.
What to See & Do
- O’Brien’s Tower – Climb the 1835 stone tower for 360° panoramas of the Aran Islands, Galway Bay and five Irish counties on a clear day.
- Visitor Centre Exhibits – Interactive displays explore 300‑million‑year‑old sedimentary rocks, river‑channel fossils and the modern wildlife that inhabits the cliffs.
- Hag’s Head & Moher Tower – Walk the southern headland to view the “witch’s head” rock formation, a natural arch and the ruined Napoleonic‑era Moher Tower, perfect for photography.
- Wildlife Watching – The cliffs form an Important Bird Area supporting ~30,000 birds of more than 20 species, including puffins, razorbills, kittiwakes, guillemots and occasional peregrine falcons. Grey seals, dolphins, minke whales and basking sharks are often seen from the sea.
