What's the story here?

Lenan Bay is a remote inlet on the eastern shore of Lough Swilly to the south of Lenan Head, about 3 miles south of Dunaff Head and on the Inishowen Peninsula. The cliffs surrounding the bay slope down to a lovely sandy beach and Lenan Head provides partial shelter to the bay which is entered close to the south of it. A small concrete pier, called Lenan Port, is situated on the northern edge of the bay where a landing may be possible and a handful of small local fishing boats have moorings close by. There is no other development here save for a small cluster of cottages at Leenankeel at the southern end of the bay.

Depths of up to 7 metres can be found in the bay which gradually decreases to the drying sands at the head. The bay is open to the west exposing it to the prevailing westerly winds and to the swell which sometimes rolls into the Lough, which can make life uncomfortable when moored. So this is the reserve of some fair summer weather conditions. The pier has about 1 metre of water at its head but is usually subject to a surge or swell, making it impracticable to come alongside and dry out.

How to get in?

Approaches to the Lough Swilly can be found in northwestern Ireland’s coastal overview for Erris Head to Malin Head . A set of waypoints to assist with the run up the lough as far as Fanad can be found in the Lough Swilly route . The entire length of Lough Swilly is marked with various easily identified navigation lights along the main deepwater shipping channel. The fairway is about 3½ miles wide at its entrance from which it gradually narrows to a width of 2½ miles at Lenan Bay opposite Crabbin Point.

Drift netting for salmon takes place throughout the summer months within the lough particularly in Lenan Bay and together with several other marine farms care should be taken to avoid them, their charted positions are approximate and additional farms may be established without prior notice.

Anchor according to wind and conditions in excellent sand holding. Land by dinghy on the beach or at Lenan Port.

Why visit here?

Lenan Bay, in Irish Cuan an Líonáin, is a lovely crescent-shaped bay that is open to the west. It has a beautiful sandy beach with low lying farmland that slopes down from the hills and cliffs to the shoreline on the mainland to the east.




Above the bay, on Lenan Head, stand the remains of Lenan Head Fort, sometimes spelt Leenan, that is one of a total of seven defensive forts built by the British to defend the deep-water anchorages of Lough Swilly. The fort is defended by a ditch system with fortifications at the corners. It was constructed in tandem with Dunree Fort in 1895 and is an unusual British fortified site because it was started so late. As such it is constructed with concrete caponiers in an extensive ditch system that climbs the hill to the headland. It was initially armed with 3 breech-loading 9.2" guns but was refitted in 1911 with 2 newer 9.2" models that had a 12-mile range, the largest in Ireland at the time. The gun positions are linked by extensive underground magazines and these passages are still in remarkably good condition.

On 6 December 1921, the Anglo Irish Treaty was concluded that included provisions by which the British would retain sovereignty over three strategically important ports known as the Treaty Ports. This included a number of coastal artillery defences, including the Defences of Lough Swilly, which were retained by the British Government on a Care and maintenance basis. All three military sites were fully transferred to the Republic of Ireland in 1938 and, although the battery was manned by the Irish Army in the Second World War, the fort was decommissioned in 1952.

The Victorian site was only used for less than 40 years and never fired a shot in anger. Yet it still remains standing, isolated on Lenan Head for over 120 years. Much of the fort area comprises the former barracks which were partly demolished and have not stood the test of time well. All that remains of them are the redbrick chimney stacks and the best-preserved building is, surprisingly, the squash court. But the highlight of the site are the three gun emplacements at the western end. Some of the original signage remains in the tunnels between.

Remote Lenan Bay has to one of the most picturesque havens of the Irish coast. In the midst a remote area the rough mountains slowly soften to green pastures, reaching a quiet beach and quay, where anglers and local fishermen mingle. The beach is simply beautiful and it makes an ideal starting point for a variety of hiking trails into the magnificent Urris Hills.



From a sailing point of view, this is a useful scenic bay in which to drop anchor whilst making passage during easterly conditions. It also offers an overnight stay after rounding Dunaff Head before proceeding further into Lough Swilly.
