Allt-yr-yn forms an electoral ward (district) and coterminous community (parish) of the city.

Some of the district is built upon the Ridgeway, Newport, with part of the ward offering views of surrounding areas such as Twmbarlwm.

On the west side of Allt-yr-yn heights is a Local Nature Reserve containing ancient woodland, meadows and five ponds.

[6] There was once a hospital in the ward, but this was deemed surplus to requirements and the site is now the Allt-yr-yn Heights estate.

Allt-yr-yn is the home of Nicky Wire, bassist and secondary vocalist of the Welsh alternative rock band Manic Street Preachers, and his family.
