If you visit one place in West Sumba, make it Weekuri Lake. This extraordinary saltwater lagoon sits on the southwest coast of Sumba Island and delivers one of the most jaw-dropping natural swimming experiences in all of Indonesia. Crystal clear turquoise water, dramatic limestone cliffs and almost no crowds -- Weekuri Lake is the hidden gem that makes the journey to Sumba worth every hour of travel.
What is Weekuri Lake?
Weekuri Lake -- known locally as Danau Weekuri -- is a natural saltwater lagoon formed where the ocean pushes through cracks and channels in the surrounding limestone rock formations. Unlike a conventional lake fed by rainwater or rivers, Weekuri is continuously refreshed by the sea, giving it exceptionally clear water with a vivid turquoise and teal colour that shifts dramatically depending on the angle of the sun.
The lagoon sits just metres from the open Indian Ocean but is completely protected from waves and currents by the rock barrier surrounding it. The result is a calm, safe and impossibly beautiful natural swimming pool that feels almost supernatural.
Why Weekuri Lake is Unlike Anywhere Else in Indonesia
Sumba remains one of Indonesia's least visited islands despite being just over an hour's flight from Bali. Weekuri Lake encapsulates exactly why travellers who make the journey feel so rewarded. Where Bali's most famous waterfalls and swimming spots are now crowded with tourists, Weekuri still feels genuinely undiscovered.
The colour of the water is the first thing that stops visitors in their tracks. Depending on the time of day and season it shifts between deep emerald green, vivid teal and brilliant turquoise -- a natural phenomenon created by the combination of ocean minerals, limestone geology and tropical light.
Swimming here is unlike anywhere else. The water is crystal clear to several metres depth, naturally temperature-regulated by the ocean connection and completely free of any currents or waves. It is safe for all swimming abilities including children.
Getting to Weekuri Lake from Tambolaka Airport
Weekuri Lake is located approximately 60 kilometres southwest of Tambolaka Airport (TMC) in West Sumba. The drive takes between 1.5 and 2 hours depending on road conditions.

The roads in this part of West Sumba are mostly paved but can be narrow, winding and unpredictable. Hiring a local driver or guide is strongly recommended. Not all roads are accurately mapped on Google Maps in this region of Sumba.

Best Time to Visit Weekuri Lake
Dry Season (May to October) -- Highly Recommended
The dry season is the best time to visit Sumba and Weekuri Lake. During these months:
- Skies are clear and blue providing the best light for photography
- Water visibility is at its maximum
- Roads are in good condition
- The lagoon colour is most vivid
Wet Season (November to April)
Weekuri is still beautiful in the wet season and significantly less visited. The surrounding landscape turns brilliantly green during the rains and the contrast with the turquoise water is stunning. Road conditions can be more challenging during heavy rain periods.
Best Time of Day
Arrive before 9am for the best experience. Early morning light produces the most vivid water colours and you will have the lagoon almost entirely to yourself. By late morning tour groups begin to arrive and the atmosphere changes significantly.
What to Expect at Weekuri Lake
The Swimming Areas
The lagoon has two main swimming sections:
Lower Pool -- Closest to the ocean entrance. This is the larger and more popular swimming area. Local children often jump from the surrounding rocks here making for spectacular photos. The water depth varies between 2 and 5 metres.
Upper Pool -- A slightly smaller and calmer section further from the ocean entrance. The upper pool tends to have cleaner water and fewer visitors. This is the recommended spot for snorkelling.

Weekuri Lake has basic facilities including:
- A small parking area (free)
