This tower-house, said to have been built in 1570 by an English soldier, Captain Browne, is badly ruined but is still of considerable interest. Rectangular and fairly small in ground plan, it was entered by a door in the north-west wall which has a draw bar socket and a murder-hole. To the left of the door was a stair to the next floor. There are two ground floor rooms, the larger with a semi-circular vault built on plank centring and the smaller with a pointed vault built on paired wicker mats. The smaller room, once thought to be a secure boat bay, may be just a storeroom (compare nearby Sketrick). There were two storeys above, but the upper parts are ruined. Part of the bawn wall survives to the south-west, cut into the hill.

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.

There are over 30 dedicated no traffic touring cycling routes in the North Strangford Lough National Nature Reserve, catering to various skill levels. This includes 14 easy routes, 14 moderate routes, and 2 more challenging options.
For an easy and family-friendly ride, consider the Nendrum Monastery Ruins – Sketrick Castle loop from Castle Espie Wetland Centre, which is just over 25 km. Another excellent option is the Mahee Castle – Nendrum Monastery Ruins loop from Comber, spanning about 21 km. Both offer relatively flat terrain and scenic views.
Yes, many of the routes are circular, allowing you to start and end at the same point. For example, the Nendrum Monastery Ruins – Sketrick Castle loop and the Mahee Castle – Nendrum Monastery Ruins loop are both excellent circular options for touring cyclists.
The terrain varies, but many no traffic routes, especially those closer to the lough shore, are relatively flat. You'll find a mix of paved surfaces and quiet country roads. Some routes, like the Comber Greenway, are entirely traffic-free paths. More challenging routes might include some gentle climbs, particularly around areas like Scrabo Hill.
The routes offer stunning views of Strangford Lough, the UK's largest sea lough, with its unique mud and sand flats. You can spot migratory wildfowl, especially pale-bellied brent geese in autumn. Notable landmarks include the iconic Scrabo Tower, historic sites like Nendrum Monastery Ruins and Mahee Castle, and the picturesque islands formed from drowned drumlin hills. The Scrabo Quarry Path loop from Newtownards offers views of Scrabo Tower.
While the routes themselves are generally open, it's important to keep dogs on a lead, especially in nature reserve areas due to wildlife. The Comber Greenway is a popular traffic-free path where dogs are often walked, making it suitable for cycling with a well-behaved dog on a lead. Always check local signage for specific restrictions in sensitive wildlife habitats.
The spring and summer months (April to September) generally offer the most pleasant weather for touring cycling. However, autumn (September and October) is particularly spectacular for wildlife enthusiasts, as over 60% of the world population of pale-bellied brent geese arrive, drawn by the abundant eel-grass. Winter cycling is possible but can be cold and wet, requiring appropriate gear.
Several routes pass by towns and villages where you can find amenities. For instance, the Comber Greenway leads directly into Comber, which has cafes and pubs. The 'Scrabo Tower to Strangford Lough' route, managed by the National Trust, is known for its opportunities for café and pub stops. Daft Eddy's, a family-run bar/restaurant, is also accessible by bike across a causeway.
Yes, public transport can get you close to some starting points. The Comber Greenway, for example, starts near Belfast city centre, which is well-served by public transport. From Comber, you can connect to quiet country roads leading along the lough's shoreline. For specific route access, it's advisable to check local bus services to towns like Newtownards, Comber, or Downpatrick.
The area is highly rated by the komoot community, with an average score of 4.7 stars from over 60 reviews. Reviewers often praise the tranquil, traffic-free sections, the stunning coastal scenery, the abundance of wildlife, and the historical sites encountered along the routes. The sense of peace and natural beauty are frequently highlighted.
Yes, a unique feature of the area is the picturesque ten-minute ferry crossing between Strangford and Portaferry. This ferry can accommodate bikes and offers an excellent way to extend a touring cycling adventure, allowing you to explore both sides of the lough.
