Although some residents of Cardiff may refer to it as a mountain, its height restricts it from being declared a mountain. It is owned by Cardiff County Council and operated as public land, and looks down onto the village of Rhiwbina in the northern suburbs of Cardiff, Wales.
It is mostly noticed for its large transmitter which is owned by British Telecom and space is then leased out to companies this aerial mast that helps boost television and radio signals from Cardiff across to the South Wales Valleys. There is a heavily vandalised former military bunker located near the masts. Although public access is possible to this location, the land is privately owned and presently leased to a riding school, so no dogs may be taken there and care should be taken to act responsibly and remove all litter.
Just like the Garth Mountain a mile or so away, the Wenallt Mountain can be seen over most of the Cardiff city centre, and on a sunny clear day can also be seen as far away as Weston-super-Mare, which is some eighteen miles away over the Bristol Channel in the southwest of England.
The south facing slope of the hill overlooking Cardiff is now covered in trees, whereas not so long ago in the early-1970s it was covered in ferns and bracken with a network of paths criss-crossing the slope. Bluebells are abundant in May.
