Gunung Lambak, at 510 metres, is Kluang's most accessible nature destination and the dominant local peak. The mountain is an inselberg — geologically distinct from the surrounding landscape, rising steeply from the flat Johor lowlands. A well-maintained trail network with wooden bridges makes the ascent accessible to walkers of average fitness; the summit takes about two hours at a steady pace.
The base of the mountain has a recreational park with a car park, picnic areas, a children's playground, chalets, and a swimming pool. Long-tailed macaques, pig-tailed macaques, and dusky leaf monkeys are regularly seen along the trail. From the summit, on a clear day, you can see across the lowland rubber and palm oil plantations to the far ridgeline.
The mountain is southwest of Kluang town, about 5 km by road. Early morning is the best time to visit — the trail is shaded, the wildlife is active, and the midday heat is avoided.
