Monaghan lies on the drumlin belt in north-central Ireland. The northern half is almost surrounded by Northern Ireland. There are many reasonable sized lakes and stretches of beautiful green drumlins as far as the eye can see. And also the low mountains of Sliabh Begh in the northwest of the county, stretching into Northern Ireland.
Monaghan is one of the few Southern counties to have suffered mildly in The Troubles due to its proximity to Northern Ireland, so the same precaution should be taking here as in Northern Ireland: avoid conversations about politics and religion, and also take heed that some areas in Monaghan on the border are Republican.
Monaghan like the rest of the Republic is for the most part English-speaking, even though Irish is the first official language. Typical of midland counties (except for Meath) it has no Gaeltacht community.
There's a good regular bus service provided by Bus Éireann from all the close major towns like Dublin, Dundalk, Drogheda and Newry in Northern Ireland, plus local buses to take you between towns.
Though Monaghan is within the hilly drumlin belt, cycling would still be a must, especially in good weather, as the scenery is awe-inspiring. The roads have fairly improved except for some dodgy country lanes. Driving is also a bliss as you can take in the lakes on the main roads along many of its scenic drives.
- Lough Muckno Leisure Park, Castleblayney. A leisure park boasting many amenities.
- St Joseph's Church, Carrickmacross. Built in 1866, it boasts 10 windows by the renowned stained glass artist Harry Clarke, and in addition has noteworthy Stations of the Cross.
Because Monaghan is on the drumlin line, it gives way to a landscape that looks like a Basket of eggs from a height. There are many lakes large and small in the county and low lying mountains with walking trails in the northwest of the county. It also has many fine buildings and houses within its towns and also facilities to spoil yourself. Also every year there are small festivals around the county.
