The Inishowen Peninsula is in County Donegal. Inishowen has several harbors, some of which are used for commercial fishing purposes, including Greencastle. The village of Fahan has a privately built Marina.
Inishowen people say that if Donegal is the forgotten county of Ireland, then Inishowen is the forgotten part of the county! Its proximity to Northern Ireland has meant that is has been greatly affected by "the Troubles" there up to 1998, with many of those wanted by the authorities in Northern Ireland going "on the run" across the border into Inishowen.
English is the first language here, although some may greet you in Irish.
The easiest way to see the peninsula is by car, but touring by bicycle is rewarding, if energy sapping, due to the hilly terrain.
Most towns in the region have restaurants and bars that serve food and hotels, which also serve food are numerous, often located outside of the towns. Watch out for the golfclubs in the area also, as they often serve good food at reasonable prices and you don't have to play a round of golf to avail of the facilities.
As stated above, the region's proximity to the border and Northern Ireland has created safety problems in the past. Nowadays, with the Peace Process bedding in, Inishowen is as safe to travel as any other part of the country, with the usual common-sense approach to pickpockets, etc..
Care should be taken when driving in Inishowen due to the narrow roads and sweeping bends. Young people driving too fast on these roads can cause a hazard and Inishowen has a high road accident rate in comparison to other parts of Ireland.
Inishowen has a number of attractive beaches often deserted, but the sea around this area also has strong currents. Check with locals before bathing.
