Weekuri Lake: Sumba’s Secret Saltwater Pool Where the Sea Takes a Breath
A sheltered saltwater oasis on Sumba’s rugged southwest coast—perfect for floating, photography, and cultural side trips.
The path to Weekuri Lake narrows to a single worn track between low limestone ridges, and then opens like a held breath: a perfect, glassy crescent of blue cupped against a ragged coastline. Saltwater slips through invisible channels and pools here, smoothing the sea’s rougher moods into a calm inland mirror that invites you to float, drift, and watch the sky rewrite itself across a surface that changes with every tide. Locals call it Waikuri; on maps and in many travel notes it appears as Weekuri Lake. Either way, it’s one of Sumba’s small, startling spectacles—an intimate coastal lagoon where swimming feels like entering a natural infinity pool.
Trail Wisdom
Go early for glassy water
Morning offers calmer conditions and clearer reflections—arrive before 9am to avoid wind and mid-day crowds.
Use reef-safe sunscreen
The lagoon and nearby reefs are sensitive—choose biodegradable sunscreen to reduce impact.
Wear sturdy sandals
Entry points are limestone and can be slippery; closed-toe water shoes make access safer.
Respect local customs
Cover up when leaving the water near villages and ask permission before photographing people or ceremonies.
