Description
The two reservoirs are side by side, accessed via a well-made path (it can get a bit muddy in wet weather). The reservoirs are surrounded by grass, mature trees and hedges. Please keep to signposted trails and stay off the grassed areas at all times (they hold rare and protected Waxcap fungi species).
Regular species on the lakes include Tufted Duck, Little Grebe, Lesser Black-backed Gull, Great Cormorant, Great Crested Grebe ,Eurasian Coot, Mallard, plus many others. The water's edge attracts Grey Wagtail, Pied Wagtail Little Egret, Common Sandpiper and Common Kingfisher .
The surrounding areas can hold many of the passerine species you'd expect to find in the woodlands of South Wales, depending on the time of the year.
Parking is free for the first two hours, and there is a nice cafe (with toilet facilities). A small hide is situated on the northern side of the smaller Lisvane reservoir, which is particularly useful in the winter when the path around this reservoir is closed, to prevent disturbance.
This site has attracted a selection of rarer species over the years, so it's worth checking reports to see if there is anything unusual around. Great Northern Diver, Red Phalarope, Red-necked Phalarope, Black Tern, Ring-necked Duck have all been seen. A total of approximately 140 species have been recorded here.
