Mlawula Nature Reserve, Protected area in northeastern Eswatini.

Mlawula Nature Reserve is a protected area of about 165 km2 (64 sq mi) in north-eastern Eswatini, bordering Mbuluzi Game Reserve, Simunye Nature Reserve and Hlane Royal National Park. Its land runs from the Lubombo mountains down across the Mbuluzi river valley, with acacia woodland and open bush.

Mlawula was first proclaimed a protected area in 1914, then deproclaimed and divided into cattle ranches. Conservation returned in 1978 when a donated tract became Ndzindza Nature Reserve; the Mlawula Estates were bought soon after and Nyala Ranch was donated, assembling today's reserve.

The reserve's name comes from the Mlawula Estates, purchased after the 1978 donation of the land that became Ndzindza Nature Reserve. The adjacent Nyala Ranch was later donated, and the reserve now borders Mbuluzi Game Reserve, Simunye Nature Reserve and Hlane Royal National Park.

The reserve has more than 50 kilometers of walking trails where visitors can explore and move freely without special vehicle restrictions. The absence of dangerous predators makes hiking safer and more relaxing for visitors of all abilities.

The reserve is home to around 1,000 different plant species and serves as a major refuge for bird watchers. This is because roughly 70 percent of the country's bird species can be observed here, making it a hotspot for bird lovers.
