A pathway along the lake allows for closer inspection of the birds. For example, swans, mallards, little grebe, moorhens, and coots are usually present. There is an observation area to view the birds and other wildlife. Parking is available. In July 2000, Kiltonga Nature Reserve became the first site in the UK to be awarded BT Millennium Miles status.

Helen's Bay Beach is one of two excellent beaches found in Crawfordsburn Country Park. These beautiful sandy beaches are by far the best within the Belfast area and as such are exceptionally popular and well used. Helen's Bay Beach is gently shelving and has excellent water quality making it ideal for bathing. The country park provides an excellent back drop to the beach, with wooded headlands, meadows, quality walks and good facilities. There are disabled toilets and disabled parking a short distance from the beach. A path suitable for wheelchair users leads from the car park to a path running adjacent to it. Nearby Crawfordsburn Country Park has a Cafe / Restaurant, Car Parking, Picnic Sites,Toilets, and a Visitor Centre.

This is the best example in Northern Ireland of a pre Norman ecclesiastical enclosure with its buildings. Nendrum is associated with St Mochaoi who died at the end of the 5th century, and is linked with St Patrick in a much later source. Notices of Nendrum clergy, including three bishops, begin in the 7th century and the excavation of a sophisticated tide mill on the shore near the site has shown that the mill was active in the early 7th century, which underlines the early importance of Nendrum. References continue until a fire in 976, perhaps a Viking raid, when the head of the church (erenagh) was burned in his house. In the late 12th century a small Benedictine monastic cell was founded on the site, but by 1302–1306 this was the parish church, abandoned for Tullynakill on the mainland in the 15th century. H.C. Lawlor excavated the site from 1922 to 1924, when enclosure walls, church and round tower were restored. The glacial hill is crowned with three concentric walled enclosures, irregularly oval in plan. Little is known of the outer cashel, only partly in state care. In the middle cashel on the south-west side are circular platforms for huts, which excavation suggested were craft workshops, and a rectangular building known as the ‘schoolhouse’, also a workshop. In the inner cashel were the most important buildings, including the church with its graveyard and the base of a round tower north-west of the church. The west wall of the church was rebuilt in the 1920s, incorporating a reconstructed sundial at the south-west corner. Finds from the 1920s excavation, including the well-known bell of Nendrum, are in the Ulster Museum and Down Museum at Downpatrick. Underwater archaeological work in the 1990s showed that there is a stone jetty south-east of the enclosure, now inundated in the lough, and medieval pottery was found close by.

Love spending time here. There is a park bench to the far east corner, and to the left of that hosts one of the best views of the Lough. When tides out you can see traces of the old Salmon fisheries. Its so quiet, and there is a picnic area just to the side of the visitors centre. The site also boasts fragments of an early Sun Dial that have been placed by the entrance to the Church.

This impressive fort was built in the 20th century and is one of the best preserved forts in the British Isles! It played a huge role in the defenses of Belfast during WW1 & WW2.
