From Donaghadee visitors can enjoy spectacular views across the Irish Sea, where on a clear day you can see all the way to Scotland, only 20 miles away by sea. It was the province’s principle port before Belfast developed. The Harbour was built in 1820's to the design of John Rennie and is part built of limestone from Wales known as "Anglesea marble". On the harbour is Donaghadee's impressive lighthouse, which was built in 1836 and was the first lighthouse in Ireland to be lit by electricity. Sit and rest in the harbour with a bag of chips from Rainy's on the High Street ( on the hill as you roll in to town from Millisle ) Best fryers in the town. Perfect recovery after a long cycle, Irelands oldest Pub - Grace Neills, is only around the corner.

Ballydorn, or 'The Dorn' as it is locally known, is a beautiful and popular mooring ground with a short-stay pontoon attached to a permanently moored lightship called The LV Petrel that is now the Down Cruising Club headquarters. The LV Petrel was commissioned by the Commissioners of Irish Lights in 1913, and built by the Dublin Drydocks Company. This Lightship spent most of its previous working life at Blackwater Bank on the River Blackwater, Wexford. It was then sold in 1968 to Hammond Lane foundries in Dublin, before being saved to use as the cruise club HQ. The boat is registered as a national historic ship in the UK.

This large tower house was built in the mid 15th century and was actively involved in warfare during the 16th century. It would have originally been four storeys high with a boat bay and subterranean passage. There were four chambers at ground level, the largest had a vault built on wicker centring and two ovens. The small unlighted room could have been a lock up or treasury. The tower-house was relatively complete until half of it collapsed in a storm in 1896. Part of the bawn wall survives to the north and east of the castle.

Ringhaddy Sound is located on the western shore of Strangford Lough to the west of Islandmore. With its unusual swollen hills it is a real joy to cycle. Descend into the sound, and enjoy the atmosphere. A Castle ruin and Church sit further on the Peninsula, but alas they are on private land. It is possible to arrange access from the land owner however. There is also a Beautiful mooring with a Boat Club that has full facilities if needed. Heres a bit about the Castle. This is one of the most completely surviving tower houses in the county, retaining its gables and formerly an original wooden window. There were at least two main phases of construction at this site. The ground floor, which had a stone vault, dates from the 15th century, while the upper parts were rebuilt in about 1600. It is rectangular in plan with small turrets at the north-east and south-west angles, one with the stair and the other with a latrine chute. There are large fireplaces on the first and second floors, and an attic in the roof. A distinctive stone rainwater spout projects from the east side. The castle seems to have changed hands between Bryan McArt and the English in the early 16th century, and it is likely that the earlier castle was McArt’s stronghold, slighted when he withdrew, and rebuilt by the new English owner. Underwater investigation has confirmed the presence of a stone slipway beside the castle, and water transport was clearly of great importance in this location.
