Gunung Lang is located just north of the city off Jalan Kuala Kangsar and easily accessible by road. The lake was originally a disused mining pool. It has a lake surrounded by greenery and limestone outcrops and was first identified and adopted by the Rotary Club of Ipoh for development into a family recreational park; much publicity was given but with very little progress.
Covering an area of 30.35 hectares out of which 14.16 hectares consists of the lake, the park is divided into two sections.
It was opened in October 2000 and was closed for renovation and reopened in 2004. There is also a man-made cascading waterfall (operates a few hours daily) with a large sign on top of the hill.
Across the lake, which is stocked with fish such as lampan, tilapia and keli, lies an landscaped park that is accessible only by boat. The boat trip, which takes about five minutes from the jetty at the office building, costs RM3 for adults and RM1.50 for children for a return trip.
Situated in the park are two watch towers, three kampong houses, a playground and mini zoo with deer, ostrich and rabbits. There are picnic grounds, a campsite, foot-paths, a boardwalk along the lake and plenty of Heliconia and Bougainvillea bushes.
The park is open from 8.00 a.m. to 6.00 p.m. daily except on Fridays when it is open till 4.00 p.m. There are few visitors during weekdays, however during weekends, the place is crowded with family having picnic and spending quality time together.
