Greaghlone Lake

Greaghlone Lake is on the EPA's list of places people swim, though not one of the waters it tests in County Monaghan, 4.2 km south-east of Shercock. The State does not test the water here, so there is no grade. The register records parking. It leaves 2 of the questions on this page unanswered, and those are shown as not recorded rather than as a no.

How journey planning works
Destination, access and nearby stops

Greaghlone Lake is in Shercock, County Cavan. Routes here end at the point the map records for this place. The entrance has not been verified, so the last few metres are for you to judge.

The nearest settlement is Shercock, 4.2 km south-east of the beach. The register records parking here. Getting to the town is not getting to the beach, so the journey below is worked out to the beach itself and the last stretch on foot is measured rather than left out.

Questions people ask

Is the water clean at Greaghlone Lake?
Greaghlone Lake is on the EPA's list but is not one of the waters it tests, so the State works out no grade for it and none exists. Nothing here says the water is clean or dirty, because nobody has published either.
Is swimming restricted at Greaghlone Lake?
The register leaves this blank for Greaghlone Lake, which it does for the 89 waters it does not monitor. A blank is not a no. Check with Monaghan County Council.
Does Greaghlone Lake have a Blue Flag?
No. A beach without one can still have excellent water: the Blue Flag also asks for facilities, lifeguards and information boards, which a quiet strand may not have.
Is there a lifeguard at Greaghlone Lake?
No. The register records no lifeguard here, so nobody is watching the water.
How do you get to Greaghlone Lake without a car?
No stop in the national timetable is within two and a half kilometres of Greaghlone Lake. That is what the published timetable holds rather than a statement that nothing goes near: services that run on demand, and routes that file no schedule, are not in the feed at all.
Where does this come from?
The Environmental Protection Agency's list of places people swim, which it calls the bathing water register, read on 2026-09-20, where this record was last changed on 2025-03-31. Water quality, awards, lifeguards and facilities are the EPA's own fields, and a field it leaves blank is shown as not recorded rather than as a no. The distance to the nearest town is this site's own measurement, in a straight line.

Water quality, awards, lifeguards, toilets, parking and access are the Environmental Protection Agency’s own fields, from its bathing water register, read 2026-09-20. The classification covers four years of sampling and is not a reading for today: after heavy rain the water can be worse than the classification suggests, and the EPA and the local authority post notices when it is. Positions are the EPA’s grid references, projected to latitude and longitude. Journeys are the National Transport Authority’s published timetable.
