Matayangu waterfall, Sumba: the jungle trek and what to know

The trail starts in tall grass and turns into forest so dense that the light goes green. Roots and sharp limestone underfoot, the hum of insects, a hornbill's wingbeats somewhere above the canopy. Then, down the last steep steps, the sound arrives and the forest opens on a cliff where a column of white water pours from the rock into a pool the colour of jade. For many travellers this is the most memorable waterfall in Sumba, precisely because it is hard to reach.

What Matayangu is and why go

Matayangu (also written Mata Yangu) lies in Waimanu village, in the Katikutana area of Central Sumba, inside Manupeu Tanah Daru National Park. The year-round fall drops about 75 m from a river that emerges from a cave; in the rainy season a second fall of about 130 m appears beside it. It sits on the same water course as Lapopu, about 2 km upstream.

Local Marapu communities consider the falls sacred. Reporting from Central Sumba describes the belief that ancestral spirits dwell here, that a cave at the source holds an ancient tomb, and that the pool has no bottom. The name is often explained as "spring of life" or "place of the ancestral spirits". The forest around the trail is good habitat for the Sumba hornbill and the endangered Sumba cockatoo.

How to get to Matayangu

• From Waikabubak: about 20-25 km, but allow roughly 1-1.5 hours by car: the roads are narrow and signage is confusing, so ask the way or come with a driver who knows it.
• From Tambolaka airport (TMC): about 65 km, roughly 2-2.5 hours to the trailhead via Waikabubak.
• From Waingapu (WGP): about 130 km, realistically 3.5-4.5 hours to the trailhead, so plan a night in West or Central Sumba.

At the end of the road, local guides wait near the last houses. The walk starts with roughly 1.5 km of flat, often muddy path through grass to a small hut, then enters the forest and climbs and drops steeply on a narrow, unmarked trail with sharp limestone, ending with a long flight of steps (one source counts more than 500) down to the pool. Expect about 1-1.5 hours each way, longer when wet, and allow 4-5 hours for the whole outing.

When to go and the best time of day

The dry season, roughly May to October, has the easiest, least slippery trail and the clearest water for a swim. The rainy season (roughly December to March) brings the second, taller fall and a huge wall of water, but the trail becomes muddy, slow and more dangerous, with leeches. Start early in the morning: it is cooler in the forest, and you will be back before afternoon showers or heat build up.

Tips and etiquette

• Hire a local guide at the end of the road: the trail is not marked. The fee is often left to you, so agree the amount clearly before you set off. An official park fee of around IDR 150,000 for foreigners has been reported, although it is not always collected.
• Wear proper shoes with good grip, long socks or trousers against grass and leeches, and bring at least 1.5 litres of water per person and a snack.
• Swimming: only in calm, clear dry-season water and only if your guide says it is fine. The path down to the swimming spot is steep.
• Ask your guide whether there are places you should not enter or photograph, and do not shout, leave rubbish or move stones at this sacred site.
• There are no facilities at the falls. Tell someone your plan and do not attempt the trek alone.
