If you’re looking for a peaceful escape in Sumba, put Weekuri Lagoon—also sometimes spelled as Waikuri—on your list. Tucked away in Kalena Rongo Village in Southwest Sumba, it’s about 40 km from Tambolaka, or around 1.5 to 2 hours by motorbike or car. The journey might be long, but the calm, clear waters and quiet surroundings make it worth the ride.
The lagoon is oval-shaped, about 150 meters long and up to 50 meters wide. Depth ranges from just 30 cm to around 2.5 meters—but during high tide, it can rise to 5 meters in certain areas, so make sure to keep an eye on the water level before jumping in.
Why Visit?
Weekuri (or Waikuri) Lagoon is a natural wonder that feels more like a giant open-air spa than a tourist destination. What makes it special isn’t just the quiet vibe—but the unique mix of saltwater and freshwater. Seawater seeps in through coral rocks, while natural springs feed into the lagoon, giving the water its signature green-blue hue.
You’ll notice the temperature shifts as you move around—some spots are surprisingly warm, others refreshingly cool. Whether you’re swimming, floating, or just dipping your feet, it’s a great way to relax and enjoy Sumba’s natural beauty.
What to Do or See
As soon as you arrive, you’ll probably want to jump right in. The water is salty but calm—no waves here—so you can swim, splash around, snorkel a bit, or take photos from the wooden bridge that’s perfect for those Instagram-worthy shots.
While it’s not a major snorkeling destination, the water is so clear that you can still enjoy looking at the rocky bottom and some small fish if you bring your own gear. Sometimes you’ll see local kids jumping off the rocks—it’s fun to watch, but if you want to join in, make sure you know which spots are safe.
If you love exploring, Weekuri is located really close to Mandorak Beach. You can easily visit both in one day. Mandorak has striking rock cliffs and big waves—a nice contrast to the calm waters of the lagoon. However, unlike Weekuri Lagoon, the waves in this bay are often very strong, and the rocks are sharp, making swimming unsafe.
You’ll also find local souvenir vendors offering handmade items.

Practical Info
Weekuri Lagoon doesn’t have official opening hours, but it’s best to come between 8 AM and 4 PM—there’s good light, better weather, and it’s safer. (If you arrive before 10 a.m. on a weekday, there’s a good chance you’ll have the place entirely to yourself—not only without tourists, but also without local vendors.)
There is no fixed official entrance fee for foreigners; but visitors may be asked to pay a fee of around IDR 20,000 per person, sometimes referred to as a “parking charge.”
Most visitors spend 1–2 hours here—enough time for a refreshing swim, a few good photos, and a relaxed stroll around the lagoon.
The lagoon is best enjoyed in the dry season (May to September), when the water is clearer and the roads are easier to manage. The area is still pretty wild—no lifeguards, no fences—so take care when swimming or walking around. Be especially careful when entering the water—the steps are very slippery and injuries can happen easily.
These days, there are a few warungs (small stalls) nearby selling coconuts, cold drinks, and basic snacks like noodles. If you forgot to pack something, you’ll be fine.
Other Tips:
- Bring water shoes if you have them—some spots are slippery or rocky.
- If you bring a drone, ask the locals for permission first.
- Sometimes local kids offer to guide you or take pictures. If you’re not into it, a polite “no, thank you” is fine.
- Vendors might say they don’t have small change, so bring smaller bills if you can.
How to Get There
If you’re heading to Weekuri Lagoon, the closest starting point is Tambolaka, the capital of Southwest Sumba. The trip takes about 1.5 to 2 hours by motorbike or car. The route is manageable, but expect a few rough patches.
The most convenient way to get there is by renting a motorbike or hiring a local driver, especially if you’re not familiar with Sumba’s roads. Public transportation is very limited, so it’s not really recommended.

Where to Stay?
The closest accommodation is ARYA Sumba, about 8–9 km from the lagoon. However, we don’t recommend staying there. Instead, it’s better to base yourself in Tambolaka, where you’ll find more options and better infrastructure. Sima Sumba Hotel is a reliable mid-range choice, while Mario Hotel & Café offers ocean views and a peaceful setting a bit further out.
If you’re traveling on a budget, Sinar Tambolaka is a great backpacker-friendly option in the town center. With its open garden space and small pool, it’s a cozy place to relax without spending much.
Looking for something more upscale? Just a short drive away, the renowned Cap Karoso offers a high-end stay with exceptional design, dining, and service.
Is It Worth It?
Weekuri Lagoon isn’t a fancy place—and that’s exactly what makes it special. It’s quiet, natural, and beautiful. Perfect for those of you who enjoy slow travel: taking your time, soaking in the scenery, and reconnecting with yourself. Come early, bring everything you need, and get ready to fall in love with this natural wonder of Sumba.
