The Way of The Cross: The Way of The Cross is a steep uphill walk on the edge of Knockalla mountain and has the stations of the Cross lined along the way. At the top, 360m up, there are three impressive crosses and a mass alter, which has fantastic views of Lough Swilly.

Crohy Head Signal Tower: There are quite a few signal towers on the Donegal coast, with this one overlooking Aranmore Island in the background. Most of the signal towers, around 80 of them stretching all around the country, were built in the early 1800s as observation posts after French forces tried to land in the late 1790s. Most were decommissioned almost as soon as they were built, although some were re-commissioned again during the war of 1812 which was between the US and Britain, when American privateers operated off the west coast.

Faugher House: Faugher House, or O'Boyle's Castle, was built in 1611 near Portnablagh and belonged to Tirlagh Roe O'Boyle, who was granted the land after the plantation of Ulster. But O'Boyle had to later forfeit the house in 1642 after a failed rebellion. During the rebellion, a 32 gun Spanish frigate, the St Francis, with 100 Irish veterans of the Spanish army led by Eoghan Roe O'Neill anchored off Doe Castle, as O'Boyle was one of the local chieftains who supported Eoghan Roe. The building has been abandoned since the mid 1800.

Tullaghan Cross: This cross in Tullaghan, right on the Donegal/Leitrim border, has bit of an unknown origin. The cross has been dated as being from the 9th or 10th century and the local folklore says it mysteriously washed ashore from Donegal Bay one day after a storm. Another story says that it came from a monastery nearby, but the remains of such a monastery has not yet been found. The cross was erected on a hill in the village in 1778 as a 'market cross' as the law at the time allowed fairs to be held in towns with market squares that had crosses, spires or carved stones and the town wanted a market to compete with Ballyshannon.
