Set in one of the most picturesque areas of Co. Donegal, the fishing village of Greencastle lies in the north west of the Inishowen peninsula. The busy harbour is one of the most industrious in Ireland and its ancillary businesses in the village pay testament to the importance of fishing to the local economy. Lying along the banks of Lough Foyle, the village thrives on the bounty of the sea.

In summer months the Lough is widely used by pleasure craft of every description, from speed boats and water skiing, sail boats, surf boarders and yaughts. The use of the Lough for recreational purposes is a growing area, which will be further enhanced in 2001 with the development of a car ferry), which will run between Greencastle and Magilligan Point.

Its prominent location made Greencastle an important site historically, and the remnants of the village's colourful past are still evident today in the Martello Tower at the old Fort and the ruined DeBurgo castle and nearby monastery.

The village has much to offer both resident and visitor alike. Boasting an impressive array of catering establishments and bars, it attracts many visitors with the promise of freshly caught seafood and a friendly pint in a fisherman's pub.

The newly opened planetarium, housed within the Maritime Museum in the old Coastguard Station is an added attraction and a wonderful facility for the area. The coastline sweeps down towards Shrove in a line of little beaches, past the Greencastle Golf Club towards the Big White Bay with its on-shore lighthouse. The area is popular with locals and tourists alike during the busy summer months, with visitors appreciating the beauty of this unspoilt region.
