Lakes, Rivers & Waterfalls in County Kildare

Most of this list sits on one waterway. The Grand Canal crosses north Kildare on its way west, and six of the seven places here are either on it or were built to serve it. Sallins is the obvious base, a harbour town with towpath running out of it in both directions and a fast train down from Dublin. Walk west and you reach the Leinster Aqueduct, built in 1783 to float the canal over the Liffey, with the Four Potts overflow, four linked stone basins that bled floodwater off the canal, a short stroll upstream. The same stretch can be done by water: the barge from Sallins up to Digby Lock takes about two and a half hours, and the lock is still worked by hand.

Robertstown sits further west at the canal’s summit, 85 metres up, a planned village with flat towpaths for walking and cycling. Ballynafagh Lake is the odd one among the canal places, an 1780s feeder reservoir that silted up, was abandoned, and is now a 45-hectare wetland protected as a Special Area of Conservation; the loop round it is 2.25km and easy going, and the birds are the reason to come.

The Figile River is the outlier, over on the Offaly side and running south to the Barrow, with trout and coarse fishing and a waymarked loop at Clonbullogue. Towpaths here are flat and open, fine in winter but exposed in wind, and the Four Potts is best seen after rain.

Where to start

  1. Sallins – Grand Canal harbour town

    Grew up around the Grand Canal harbour and still the easiest base for towpath walks, the Leinster Aqueduct and a barge down to Digby Lock.

  2. Ballynafagh Lake – canal reservoir gone wild Ballynafagh

    An abandoned canal reservoir turned 45-hectare wetland and Special Area of Conservation, circled by an easy 2.25km loop through alkaline fen and reed beds.

  3. Digby Lock – Grand Canal barge cruise Sallins

    A slow two and a half hour barge trip out of Sallins, over the Leinster Aqueduct, to a lock still worked by hand after roughly 240 years.

  4. Figile River Kildare

    Named in the 12th-century Book of Leinster and tied to Fionn Mac Cumhaill, it runs to the Barrow with reliable fishing and a waymarked loop.

  5. Four Potts Well – Grand Canal overflow Grand Canal towpath

    Four interlocking stone basins built in the late 1700s to bleed floodwater off the canal, called unique in Ireland and a five-minute towpath stop.

Questions people ask

Can I get to any of these without a car?
Sallins has a railway station with a fast service from Dublin, and the towpath starts in the town, so the Leinster Aqueduct, the Four Potts and the Digby Lock barge trip are all reachable on foot from there. Ballynafagh Lake, Robertstown and the Figile River need a drive.
Where in the county are these places?
Six of the seven are strung along the Grand Canal in north Kildare. Sallins, the Leinster Aqueduct, Four Potts Well and Digby Lock share one stretch west of Sallins, Robertstown sits further west at the canal summit, and Ballynafagh Lake lies off it. The Figile is over on the Offaly side.
Which one is best for birdwatching?
Ballynafagh Lake. The old canal reservoir has gone back to fen and reed bed and is now a Special Area of Conservation, and BirdWatch Ireland once logged 37 species there in a single morning, Hen Harrier included. The 2.25km loop keeps you close to the water throughout.
Can you get out on the water rather than walk beside it?
Yes. Barge trips run from Sallins along the Grand Canal, over the Leinster Aqueduct and up to Digby Lock, about two and a half hours for twelve passengers, with a wood stove and a small bar aboard. Canal boat trips also run from Lowtown near Robertstown.
Where can I fish?
The Figile River has both trout and coarse fishing along its run through Offaly and Kildare to the Barrow, with an easy waymarked loop at Clonbullogue if you want a walk as well. Robertstown, at the summit of the Grand Canal, has coarse fishing off flat towpaths.
