Southern Dusky Leaf Monkeys at Khao Lom Muak (Southern Dusky Leaf Monkeys at Khao Lom Muak) The Southern Dusky Leaf Monkeys living around Khao Lom Muak are a unique and iconic species of Prachuap Khiri Khan. Their distinctive eye rings, resembling a pair of spectacles, make them easily recognizable and beloved by visitors to Ao Manao and Wing 5. Furthermore, infants are born with bright orange-yellow fur before their coloration transitions to the adult silver-grey.

Nature and Behavior

• Habitat and Diet: These monkeys inhabit the natural forested slopes of Khao Lom Muak, where the environment remains rich and undisturbed. Scientifically classified as Trachypithecus obscurus, they are primarily folivorous, meaning their diet consists mainly of young leaves, shoots, and some fruits.

• Social Structure: They live in social groups often led by a single dominant male. Observing their social interactions, particularly the playful young ones, is a highlight for many visitors.

• Familiarity: Their gentle behavior and relative familiarity with humans make them approachable, a result of careful protection by local authorities.

Visiting and Etiquette

• Viewing: Visitors can often see the monkeys at close range, particularly when they come down to feed near the base of the mountain. However, visitors are strictly advised not to feed the monkeys human food or sugary snacks, as this can be detrimental to their digestive health. Maintaining a respectful distance is key to preserving their natural behavior.

• Scenery: The area also offers beautiful coastal scenery, with clear views of Ao Manao’s turquoise sea and surrounding mountains.

• Trekking: During special periods, the mountain is opened for trekking, allowing hikers to enjoy a challenging climb and sweeping panoramic views at the summit. Along the trail, it is also possible to encounter the monkeys in their natural habitat.

With its combination of rare wildlife, stunning natural scenery, and peaceful atmosphere, observing the Southern Dusky Leaf Monkeys at Khao Lom Muak is a memorable experience for nature lovers and photographers.
