Overview
The Shannon‑Lough Derg waterway is a 238 km ribbon of river, lake and canal that threads through the heart of Ireland. It comprises 11 locks, 3 large lakes (including the iconic Lough Derg), 25 towns and 36 moorings, and is officially designated as a Blueway for safe, multi‑activity use. Whether you arrive by boat, bike or car, the waterway’s tranquil waters and dramatic scenery attract boat‑hire companies, anglers, paddlers and history enthusiasts alike.
History
The navigation follows an ancient route that has shaped Irish life for more than a millennium. Along its banks lie the 1,400‑year‑old monastic settlement of Clonmacnoise, once a major centre of learning, and the six‑arch bridge at Shannonbridge, built in the early 19th century to guard against a feared Napoleonic invasion. On Lough Derg itself, Holy Island preserves the ruins of six early churches, while the pilgrimage site St Patrick’s Purgatory offers a quiet spiritual retreat. These landmarks illustrate how the waterway has long been a conduit for trade, faith and community.
What to See & Do
Boating & Cruising
A fleet of local hire operators lets you explore the waterway at your own pace. Carrickcraft, Emerald Star and Silverline Cruisers each offer boats with 2‑10 berths, pet‑friendly policies and on‑board kitchens for self‑catering. Popular launch points include Banagher, Killaloe, Portumna and Dromineer. From these bases you can cruise to secluded coves, stop for a lakeside lunch, or simply drift under the historic bridges that line the Shannon.
Kayaking the Blueway
The Lough Derg Blueway provides well‑marked paddling routes for all skill levels:
- Mountshannon → Holy Island – a 2.5 km sheltered paddle ideal for beginners, with a landing spot on Holy Island’s historic ruins.
- Ballycuggeran → Annacarriga Loop – a 3 km out‑and‑back route that passes the University of Limerick Activity Centre and offers gentle lake views.
- Killaloe Canal → Ballycuggeran – a 5 km journey that takes you through lock gates, past Brian Boru’s fort and along tree‑lined bays.
These routes are signposted and provide safe entry‑and‑exit points for families and solo adventurers.
Fishing
Lough Derg is famed for its abundant fish stocks. Anglers can target salmon, brown trout, pike, perch, bream and roach from the lake’s many access points, including the popular spots at Portumna, Killaloe and Ballina. Seasonal licences are available through local tackle shops.
Swimming & Beaches
Three Blue Flag beaches line the Clare shore of Lough Derg, most notably Mountshannon Beach and the Portumna bathing area. Lifeguarded in summer, they provide clean water, changing facilities and easy access to nearby cafés.
Walking & Heritage Trails
The Lough Derg Way offers a 180 km long‑distance trail that weaves through villages, woodlands and historic sites. A highlight is the floating boardwalk on Acres Lake near Drumshanbo, a 600 m stretch that lets you stroll over water while listening to the gentle lapping of the lake.
Cultural Highlights
- Holy Island – monastic ruins and a chance to spot white‑tailed eagles.
- Shannonbridge 16‑arch bridge – an engineering marvel from the Napoleonic era.
- Local pubs and music sessions – towns such as Banagher, Killaloe and Portumna host traditional Irish music most evenings.
- Clare Abbey – a 12th‑century Cistercian monastery just a short drive from the southern shore of Lough Derg, offering another historic stop on your waterway itinerary.

- By Public Transport – Carrick‑on‑Shannon is served by both bus and train from Dublin, making it a convenient gateway for boat‑hire companies. Several operators also provide a shared transfer from Dublin Airport on Saturdays.
