Situated mainly atop a hill, this township is located along Old Klang Road roughly halfway between Kuala Lumpur and Subang Jaya, and was opened in the mid 1970s.
Just down the hill lies Plaza OUG, the largest shopping mall in the locality, which once contained a Parkson (previously known as Yaohan) store.
Several roads connecting OUG to Bukit Jalil and Sri Petaling, most notably Jalan Awan Besar, were added, after several years of having the project delayed.
For badminton enthusiasts, SJK (C) Yoke Nam, a primary school on Jalan Hujan Emas 6 provides a 5-court capacity hall for rent from 6pm to midnight, 6 days a week, excluding Sundays.
Within 10 to 15 minutes drive from OUG is the much popular Mid Valley Megamall and The Gardens (Kuala Lumpur) shopping malls.
Since mid-2011, The Scott Garden, a 3-level high end lifestyle retail circle was opened along Jalan Klang Lama, adding to the hustle and bustle area leading to OUG.
Plaza OUG, the oldest mall in the area, was closed in August 2022 and is in the process of demolition for a new mixed development with residential and commercial components.
