Lough Derg is the largest of the three Shannon lakes and is located in or let‘s say between the counties of Clare, Galway and Tipperary. From the twin cities Killaloe and Ballina in the South to Portumna in the North, the lake extends to a size of nearly 40 kilometres in length and ca. 16 kilometres in width respectively. There are over 60 little isles within Lough Derg. The most popular of them is Inis Cealtra, also known as Holy Island, containing the remains of a cloister settlement from the 7th century.
Due to its location at the probably most significant water route in Ireland, many settlers set foot at the banks of Lough Derg already in prehistoric times. The lake saw its peak period as “commercial water way” in the 18th and 19th century, when the most important trade route led from Dublin to Limerick via the Shannon.
Today, Lough Derg is known as an Eldorado for anglers, water sports enthusiasts and hobby captains. The touristic labelling as “Ireland‘s Pleasure Lake” is not a coincidence, given that many visitors are enjoying themselves on and next to the water particularly in the summer months. But don’t you worry! Thanks to the vast extent of the lake and the multitude of piers, there are plenty of peaceful spots, like Rossmore Harbour in the Northern Lough Derg. Besides the gorgeous landscape and the many activities on the water, picturesque places like Dromineer, Garrykennedy, Terryglass, Mountshannon or Scarrif invite for a discovery trip or a relaxing stay. Talking about the last-mentioned place by the way, the entry into the harbour via Scariff River with its narrow, reed covered access channel is an experience of its own.
