Swaziland's highest waterfall, Malolotja Falls (about 1,000 meters/3,280 feet high), is found in the Malolotja Nature Reserve about 19 kilometers (12 miles) northwest of Mbabane. This reserve, at almost 1,500 meters (5,000 feet) in elevation, has more than twenty waterfalls as the Malolotja River flows down from the highest elevations to join the Komati River at about 900 meters (3,000 feet) above sea level.
