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.
