Wild Walks: The Glen River Park
Overview
The Glen River Park is situated in a deep steep-sided glacial valley on the north side of the City, just off the North Ring Road. Once the place of Goulding’s factory in the 1850s, the site was donated to the people of Cork in the late 1960s and has since been repurposed, in part, as the Glen River amenity park.
Within this park, you will find a truly amazing display of habitats, wildlife, and walking paths, as well as an open-access sports field. Surrounded on either side by residential estates, Glen Park provides a connection between Blackpool, the Glen, and Ballyvolane.
In the basin of the valley, where the Glen River flows, there are diverse wetland areas, including ponds, wet grassland, wet woodland, and reedbeds, which provide refuge for birds, mammals, and invertebrates. Amongst the river and wet woodland, the common frog, white-throated dipper, Moorhen, Heron, Kingfisher, and many more plants and animals make their home. Further down the path, where the habitat transitions to wood and scrubland, Elm trees whose upper branches are dead, but the tree is still growing are used by birds for high perches overlooking the valley. Walking along the steep valley, covered by ferns, gorse, bramble, young oak, you may spot the common lizard basking in the sun or grasshoppers amongst the dense vegetation. Due to its long and narrow shape and steep valleys, the park is a perfect oasis from the noises of city life.
Trail entrance
There are 4 entrance points to the park (Ballyhooly Road, North Ring Road, Ballyvolane and Sunview park). We recommend Ballyhooly Road entrance as it is serviced by 2 cork City bus routes and has a good-sized carpark.
Trail length
There are 3 well-known trails in the park.
Notable Wildlife
Site 1: N ring road entrance
Common lizard
Scientific name: Zootoca vivipara
Irish name: Laghairt bheobhreitheach

Ireland’s only native lizard. Found mostly in coastal areas, grasslands and bogs. Primarily eats invertebrates such as spiders, snails and worms. Most active from March to May.

Bell heather
Scientific name: Erica cinerea
Irish name: Fraoch Cloigíneach

Native evergreen shrub common on hills and moorlands with dry, acidic soil. Flowers bloom from June to September. Petals are fused together to make the appearance of a bell. They can be found on the steep valley slopes of the Glen River Park when entering from the North Ring Road side, where the habitat is dominated by scrubland.
Sparrow hawk
Scientific name: Accipiter nisus
Irish name: Spioróg

Resident small raptor (bird-of-prey) with a long tail and blunt wing tips. Can be identified by barred breast which is orange/brown in males and brown-grey in females. The female is also larger than the male. They fly over the park, looking for small prey birds in the scrub and trees.

Common frog
Scientific name: Rana temporaria
Irish name: Loscán

Most widespread of Ireland’s three native amphibian species. Inhabits both aquatic and terrestrial habitats all across the country. Reaches a length of 6-8cm with females typically being larger than males. Although they spend much of their time in terrestrial habitats, they need wet conditions to successfully reproduce.
Two-banded longhorn beetle
Scientific name: Rhagium bifasciatum
Irish name: Ciaróg fhadadharcach

Large beetle reaching 22mm in length. Can be identified by the two pale yellow bands on the wings. Commonly found in woodlands on tree trunks and low vegetation.

Ragwort
Scientific Name: Jacobaea vulgaris

Tall perennial plant found growing in meadows and hedgerows. Blooms with white or pink flowers from June to September. The name Hogweed was given to this plant as it was previously used as food for pigs. Not to be confused with the introduced species the Giant Hogweed, which is much larger.
