Weekuri Lagoon, Sumba: how to get there, when to go, what to know

You hear the ocean before you see the lagoon: a low boom from the far side of the rocks, then a hiss as spray climbs the coral wall and falls back. On this side everything is still. The water is so clear that the sandy bottom and the dark patches of coral look close enough to touch, and its colour shifts from pale green at the edges to deep turquoise in the middle. Village children cannonball off the rocks, a few people float on their backs, and the wooden bridge creaks under bare feet.

Weekuri is the most visited natural sight in the far west of Sumba, and for good reason. This page explains what it is, how to get there, when to go and how to visit safely and respectfully.

What Weekuri Lagoon is and why go

Weekuri (also spelled Waikuri) is a saltwater lagoon in Desa Moromanduyo, Kodi Utara district, Southwest Sumba. A natural barrier of coral rock separates it from the Indian Ocean, and seawater seeps and splashes through the gaps, so the level and colour change with the tide. The name is said to come from the local word for the sea spray that forms the lake.

It is small, roughly 130-150 m long and 40-50 m wide, depending on the source. Depth ranges from about 30 cm in the shallows to around 2.5 m, and local reporting says it reaches up to 5 m at high tide. Because the water is salty you float easily, and because the ocean waves break on the outer rocks, the lagoon itself is calm. Lonely Planet describes calm, cool water on one side and the ocean crashing against rocks and blowholes on the other, which is exactly the appeal: a sheltered swim beside a wild coast.

How to get to Weekuri Lagoon

Weekuri is near the western tip of Sumba. Distances quoted from Tambolaka range from about 40 to 60 km depending on the starting point and route; allow roughly 1.5-2 hours each way by car or scooter. The road is mostly asphalt, but the last stretch is a narrow, partly rutted track, and several small roads branch off the main Waitabula-Bondokodi road towards the lagoon.

• From Tambolaka (TMC): the easiest option is a car with driver for the day, typically around IDR 1,000,000-1,500,000 (about EUR 50-75 / USD 60-90) in 2025-2026; prices vary with the season and the itinerary. Older local reports quoted around IDR 800,000.
• By scooter: possible for experienced riders, but signage is poor and the last kilometres are rough.
• From Waingapu (WGP): Weekuri is at the opposite end of the island, so plan to sleep in the west. Waingapu to Tambolaka by road is roughly 4-6 hours.

There is no public transport to the lagoon itself. See our guide on how to get to Sumba from Bali for flights.

When to go and best time of day

The dry season, roughly May to September, brings clearer water, blue skies and easier roads. In the rainy months (roughly December to March) the track can be muddy and the water less clear.

Time of day matters more than the month. Most guides suggest visiting between about 8 am and 4 pm, and an early weekday visit is quieter; weekends bring local families. Visitors who came at low tide were told the lagoon looks even better at high tide, when it is fuller and the turquoise is deeper, so check a tide table if you can.

Tips and etiquette

• Entry: there is no single official fee for foreigners. In 2025-2026 visitors were usually asked for around IDR 15,000-20,000 per person (about EUR 1 / USD 1.20), sometimes framed as a parking or access fee, and earlier visitors signed a guest book with a donation. Rubber rings have been rented for around IDR 10,000. Bring small notes.
• Safety: there are no lifeguards. Rocks and steps are very slippery, depth changes suddenly, and seeing local kids jump does not mean every spot is safe for you. Check the depth before jumping and keep away from the ocean side.
• What to bring: water shoes, a mask (small fish and a bit of coral at the northern end), sun protection, drinking water and cash. Simple stalls sell coconuts, drinks and instant noodles.
• Respect: do not stand on the coral, take your rubbish with you, ask before photographing people and ask locally before flying a drone. Lonely Planet advises against buying turtle-shell bracelets, which are illegal to export.

Nearby

• Mandorak Beach: a tiny cove between cliffs, about a kilometre away.
• Pero Beach: a fishing village and sunset beach roughly 20 km to the south.
• Ratenggaro village: tall-roofed traditional houses by the sea, a short drive beyond Pero.
• Kodi: the cultural region that contains all of the above.
