Mlilwane Wildlife Sanctuary, Protected natural area in Ezulwini Valley, Eswatini.

Mlilwane Wildlife Sanctuary covers 4,560 hectares in the Ezulwini Valley. Its southern section is mostly open grassland with middleveld vegetation rising to Nyonyane Mountain, where most visitor activities take place; the northern section reaches Luphohlo, one of the area's highest points, and is entered only on guided trails.

Ted Reilly founded the reserve on his farm in 1960, and it was officially recognised as a protected area four years later, in 1964. The land had previously been used for farming and tin mining, and its rehabilitation made it Eswatini's oldest protected area, managed by a non-profit trust.

Mlilwane means "Little Fire" in siSwati, referring to the many fires started by lightning strikes on Mlilwane Hill. The reserve is run by a non-profit trust and serves as headquarters for Big Game Parks, which also manages Hlane Royal National Park and Mkhaya Game Reserve. Visitors can stay in traditional Swazi round huts called beehives at Rest Camp.

You can explore the sanctuary through hiking trails, mountain biking routes, horseback riding, or driving your own vehicle on the roads provided. The absence of large predators makes it easy to move around freely without special safety precautions.

The wetland system near Rest Camp is home to hippos, crocodiles, and numerous water birds that stay year-round, creating a water-rich pocket within the grassland landscape. Many visitors overlook this concentrated area of wildlife activity when exploring the drier parts of the sanctuary.
