Lakes, Rivers & Waterfalls in County Roscommon

Four of the six places here sit within a short drive of Boyle, in the north of the county. Lough Gara, on the Sligo border, holds around 300 crannógs, most of them exposed when the lake was partly drained in the 1950s; it is a shallow, reed-fringed Ramsar wetland that winters whooper swans and Greenland white-fronted geese, and it fishes well for pike. The Boyle River carries on from there through the town and out towards Lough Key, and the same stretch of water gives you Knockvicar, with its lock, weir and flat riverside towpath, and Moylurg Tower, the concrete lookout raised in 1973 on the foundations of the burnt-out Rockingham House.

Boyle itself is the practical base for that group. Boyle Abbey, King House and Lough Key Forest Park are all within walking distance or a short drive of the harbour, which takes up to 28 boats on free short-stay moorings, with larger marinas downriver at Knockvicar and Cootehall.

The other two are separate outings. The River Suck runs 133 km down the western side of the county, and the waymarked Suck Valley Way follows it through nine villages and past the Castlestrange scribed stone. Kiltoom lies well to the south, on the shore of Lough Ree just off the N61 north of Athlone.

Where to start

  1. Lough Gara – Ireland's crannóg lake Boyle

    Holds the greatest concentration of crannógs in Ireland, around 300 man-made islands, on a shallow Ramsar wetland that winters whooper swans and fishes well for pike.

  2. Kiltoom – a quiet corner of Lough Ree Northwest of Athlone

    A quiet parish on the southwestern shore of Lough Ree, a short detour off the N61 north of Athlone, with a holy well and a burial mound.

  3. Knockvicar – Boyle River and alpacas Knockvicar

    Sits on the Boyle River just short of Lough Key, with a flat riverside towpath, a lock and weir, and an alpaca farm nearby.

  4. Moylurg Tower – brutalist Lough Key lookout Lough Key Forest Park

    A five-storey concrete column of 1973 above Lough Key, with a 45-minute audio loop taking in the estate tunnels, canopy walkway and island views.

  5. River Suck and the Suck Valley Way Roscommon

    Runs 133 km from Lough O'Flynn to the Shannon, with a waymarked valley walk through nine villages and coarse and trout fishing along the way.

Questions people ask

Which of these suits a family day out?
Lough Key Forest Park is the obvious choice, with a 45-minute self-guided audio loop taking in the service tunnels, the tree-canopy walkway and Moylurg Tower's view over the islands. If the tower lift is out, the platform is stairs only. Knockvicar, close by, has an alpaca farm.
Where in Roscommon do these places cluster?
Four of the six are in the north around Boyle: Lough Gara to the west, the Boyle River running through Boyle Harbour, then Knockvicar and Lough Key. Kiltoom is well to the south on Lough Ree near Athlone, and the Suck runs down the western side of the county.
Can I reach these by boat?
The Boyle River links Lough Key and Lough Gara to the Shannon, so the northern group is on the navigation. Boyle Harbour takes up to 28 boats with free short-stay mooring, and there are bigger marinas downriver at Knockvicar, with 100 berths, and Cootehall, with 50.
When is the best time for birds at Lough Gara?
Winter, when the shallow, reed-fringed lake holds Greenland white-fronted geese and whooper swans. It is a Ramsar wetland straddling the Sligo and Roscommon border, and the same water fishes well for pike if you are there in milder weather.
Is there much walking on this list?
The Suck Valley Way is the long option, waymarked along a river that runs 133 km from Lough O'Flynn to the Shannon and passing the Castlestrange scribed stone. For something shorter, Knockvicar has a flat riverside towpath and Lough Key has the canopy walkway loop.
