Parc cefn onn
Parc Cefn Onn is a country park in Lisvane in north Cardiff, one of the most naturalistic and botanically interesting green spaces in the Welsh capital, set in a steep wooded valley on the northern fringe of the city. The park is noted particularly for its outstanding rhododendron and azalea collection, which provides spectacular colour displays in late spring that attract large numbers of visitors to what is otherwise a relatively quiet and naturalistic park. The steep valley sides support ancient sessile oak woodland, and the stream running through the valley bottom provides freshwater habitat for birds and invertebrates. The park forms part of the broader green corridor along the northern edge of Cardiff linking Lisvane Reservoir with the open farmland to the north of the city, providing an important biodiversity corridor as well as a valuable recreational resource. The park is managed by Cardiff Council and is freely accessible throughout the year.
