Last updated: 23 May 2026

Overview

Cape Clear Island (Oileán Cléire) sits twelve kilometres off the rugged West Cork coast and serves as the gateway to one of Ireland’s most striking maritime icons – Fastnet Rock Lighthouse. Operated by Cape Clear Ferries, the combined Cape Clear & Fastnet Rock tours run from April to October, offering visitors a chance to step aboard a modern ferry, explore the island’s Gaelic heritage, and circle the famed “Teardrop” lighthouse at close range. The lighthouse, perched on an isolated rock eight miles out to sea, is celebrated as the tallest and widest rock lighthouse ever built in Ireland and the United Kingdom.

The Original Cape Clear Lighthouse

The original Cape Clear Lighthouse was established in 1818 on the southern side of the island. Designed by the eminent engineer George Halpin, it originally displayed a revolving light with twelve Argand burners and reflectors. The tower – now a stone ruin beside a Napoleonic-era signal tower – was once linked to the signal tower by a covered walkway that has since been removed. In the 1840s, Trinity House criticised the site for being too high and often shrouded in mist. After the tragic sinking of the American liner Stephen Whitney in 1847 – a disaster that prompted urgent calls for a more reliable navigational aid – Fastnet Rock Lighthouse was commissioned. Cape Clear Lighthouse was officially discontinued on 1 January 1854.

Fastnet Rock Lighthouse – Engineering & History

Fastnet Rock Lighthouse, often called the “Teardrop of Ireland”, was rebuilt in granite between 1899 and 1904 after the earlier cast-iron tower proved vulnerable to Atlantic storms. The structure consists of 2,074 interlocking stones, weighing up to three tonnes each, sourced from Cornwall. The tower stands 54 m tall (about 49 m above mean high water) and its white flashing light, visible every five seconds, has a range of 27 nautical miles (50 km). The light originally used a biform four-sided dioptric apparatus delivering roughly 750,000 candlepower. Inside, seven floors house a storeroom, oil room, spare bedroom, kitchen, keeper’s bedroom, and a service room with a rain-water tank and telegraph equipment. The lighthouse was automated in March 1989 and remains unmanned today.

Tour Options & What to Expect

Day Tour: Cape Clear & Fastnet Rock

The highlight of the day itinerary is a close-quarter circumnavigation of Fastnet Rock. The ferry approaches the rock twice, giving passengers unrivalled photographic opportunities of the tower against the Atlantic horizon. Throughout the journey, knowledgeable guides provide a concise history of the lighthouse, its engineering feats, and anecdotes about the lives of its keepers. Short video clips are also shown on the vessel’s screens.

After a 45-minute ferry crossing, the tour stops for two hours on Cape Clear Island. Walk the harbour, soak up the island’s lush fields, and discover ancient megalithic standing stones, a 5,000-year-old passage grave, and a memorial to the 1979 Fastnet Race tragedy. The island’s Gaeltacht status means you’ll hear Irish spoken in cafés and may pick up a few “cúpla focal”. The itinerary includes free time for a leisurely lunch at the island’s harbour café, followed by ample moments to capture the dramatic coastline and the ever-changing Atlantic light.

The tour offers free cancellation up to two days before departure and will reschedule, issue a voucher, or provide a full refund if weather forces a cancellation.

Wildlife & Photography

The waters around Fastnet and Cape Clear are a hotspot for marine mammals. Regular sightings include dolphins, porpoises and, in summer, basking sharks. Seabirds such as gannets and puffins nest on the surrounding cliffs. Photographers will find the Atlantic light constantly shifting, offering dramatic contrasts between the granite rock, the white tower, and the deep blue sea.
