Noon's Hole (Irish grid ref H12684431) lies about 5 km northwest of the centre of Boho, in the townland of Old Barr in the parish of Devenish, County Fermanagh, close to the border with Boho parish. The cave is under part of the escarpment on the east side of the Glenade Sandstone uplands. At 81 m (266 ft), this pothole was thought to have the deepest shaft in Ireland, but this honour was passed to the nearby Reyfad Pot, which contains an entrance shaft of 88 m (289 ft). The continuation of the cave system (incorporating the Afternoon Series and High Noon's) contains 3.7 km (2.3 mi) of passage, and it connects to the resurgence at Arch Cave through three cave dives, making this system the 8th deepest in Ireland, at 108 m (354 ft).Noon's Hole was previously called "Sumera", meaning "abyss", but gained notoriety and a new name in the 1820s, following the notorious murder of Dominick Noone, whose body was thrown into the cave. Ordnance Survey maps still use both names.

The Caves of the Tullybrack and Belmore hills are a collection of caves in southwest County Fermanagh, Northern Ireland. The region is also described as the West Fermanagh Scarplands by environmental agencies and shares many similar karst features with the nearby Marble Arch Caves Global Geopark. The caves are situated under the hills of Tullybrack (386 m (1,266 ft)) – which incorporates Glenkeel (373 m (1,224 ft)) and Knockmore (280 m (920 ft)) – and Belmore (398 m (1,306 ft)), and feature three major cave systems: Reyfad–Glenkeel, Noon's Hole–Arch Cave and Boho Caves. They have been described as nationally significant by the Northern Ireland Environment Agency.The caves and related features are formed predominantly in the Dartry Limestone Formation – a sequence of rocks assigned to the Asbian sub-stage of the Visean stage of the Carboniferous period. Within this formation, the Knockmore Limestone Member is also an important cave-forming rock sequence. Cave development occurred within the Quaternary period and certain features are ascribed to the Holocene epoch of the last 10,000 years. With the exception of Arch Cave, all of the caves and related karstic features listed below have been designated as provisional Areas of Special Scientific Interest (provisional ASSIs, or PASSIs), a conservation designation in Northern Ireland equivalent to SSSIs in other parts of the United Kingdom.

Killydrum (from Irish Coill an Droma 'wood of the ridge') is a townland in County Fermanagh, Northern Ireland. It has previously been referred to as Kildrome (1659) and Killdrum (1695). This townland belongs to the land division of Old Barr in the area of Boho.Killydrum is notable for the holy well named after St Faber' called Tober Faber, and its associated bullán. The area is historically linked to the home or castle of a chieftain called O'Fialain.In the Ordnance Survey Letters of O' Donovan, the surveyor notes that (the virgin) St. Faber first attempted to build her church in Killydrum near the holy well, however the first days construction was destroyed overnight by an invisible being. A passing deer indicated that there was another place where she could build her church without threat and carried her books on its horns down to Monea. When the deer continued its journey across the Sillees river, it slipped on the banks and it took a while for the books to be re-attached. This slip was thought to be brought about by a genius or sheaver (shaver)who inhabited the river who did everything in his power to prevent the spread of Christianity in the region. Once St Faber understood this she cursed the river with sterility of fish and fertility in destroying human life and may it run uphill with the following phrase MI-ADH EISC A'S ADH BAIDHTE AG RITH ANAGHAIDH AN AIRD GO LA BRATHA. Another interpretation of the name Killydrum is 'church of the ridge' which makes sense in this context.
