Darrenlas

The houses in the area are around 100–130 years old. Before the houses were built the area of Darrenlas was Glyngwyn Farm. Darrenlas primary school was built in 1907 and is located in Kingcraft Street, the school is a feeder to Mountain Ash Comprehensive School. There was another primary school in the area known as Cynon Infants but it has now closed. The local public house in the area is the Napiers arms, named after General Charles James Napier. The pub is shaped like a coffin and the reason is believed that it was once owned by an undertaker. It is also believed that the street behind the pub is called Dover Street because a number of people came to the area in the 1800s from Dover to build the streets. There are also other streets that are named after the Bruce family which is the family of Lord Aberdare such as Eva Street, Knight Street, Pamela Street, Pryce Street and Clarence Street.

There are two parks in the area - Gwernifor Park which is based near the Bryn Ifor estate and Victoria Park which is based in the forestry on the eastern side of the village. The village has 2 shops, both newsagents. The main shopping area located in the town is just a short walk away. There is also a community centre in the old Cynon Infants School building. There is also a rugby field in Darrenlas - The recreation ground which was home to Mountain Ash RFC for many years but is now used by the community for a range of other purposes. Mountain Ash public library is also located in Knight Street.
