Overview
This is a 3.3 km (2 mi) loop around King’s Island, the oldest part of Limerick and the bit most worth walking. It is one of the Irish Heart Foundation’s Slí na Sláinte (‘path to health’) routes, so it is signposted at every kilometre, flat, and free, and you can do it in about an hour. Limerick City and County Council laid it out with local community groups.
Start and finish at King John’s Castle. If you only walk part of it, walk the riverside stretch along the Shannon by Thomond Bridge: it is the best of the route, and the rest is town footpath.
History
King’s Island has been the strategic heart of Limerick since the Normans. King John’s Castle went up around 1200 on the riverbank, and a 17th-century Cromwellian fort still lies buried under the ground nearby, marked only by interpretive signs. Around the castle sit the restored Bishop’s Palace, the 19th-century Villier’s Almshouses (an early piece of charitable housing) and an old military cemetery, all of them traces of the island’s long run as a garrison and church centre.
What to see
The trail strings the island’s landmarks together in order:
- King John’s Castle – the start and finish, the Norman keep over the river, with its own paid exhibition if you want to go inside.
- Bishop’s Palace and St Munchin’s Church – the restored ecclesiastical corner of the island.
- Villier’s Almshouses – a rare survival of 19th-century almshouse architecture.
- Thomond Bridge and the Shannon – the riverside section, and the best views on the walk.
- ESB salmon weir – watch for salmon running upstream in late summer and autumn.
- The wetlands – a Special Area of Conservation on the north-west of the island (more below).
- Old military cemetery – a quiet stop at roughly the 2 km mark.
- Abbey River, O’Dwyer Bridge and Athlunkard Bridge – the eastern, river-crossing stretch, with the Athlunkard Boat Club beside the water.
- St Mary’s Church and the old city walls – the last leg follows the medieval walls back to the castle.
Each kilometre is signposted, so you can set your own pace or turn back wherever you like.
Wildlife
The wetlands on the north-west of the island are a Special Area of Conservation and the one stretch where the walk slows people down. Kingfishers, herons and teal use the water, with migratory waders passing through; early morning is the time to catch them. The ESB salmon weir gives a seasonal show when the fish run upstream, usually between August and October.
