Sumba’s Hidden Paradise Beaches: 15 Stunning Coastal Gems
With over 400 kilometers of coastline, Sumba Island possesses some of the most beautiful and untouched beaches in all of Indonesia. Unlike Bali’s crowded shores or Lombok’s increasingly developed coast, Sumba’s beaches remain largely pristine — many accessible only on foot, by horseback, or via rough unpaved roads. This guide reveals the 15 most spectacular beaches on the island, from famous surf breaks to hidden coves known only to locals.
West Sumba Beaches
1. Nihiwatu Beach
Home to the legendary NIHI Sumba resort and consistently rated among the world’s most beautiful beaches. Over 2.5 kilometers of golden sand backed by tropical forest, with a world-class left-hand surf break. Riding Sandalwood Ponies along Nihiwatu at sunrise is one of Sumba’s signature experiences.
2. Pero Beach
A vast, open expanse of sand that seems to stretch forever — perfect for galloping on horseback. Pero hosts Pasola ceremonies and offers some of the most dramatic sunset rides on the island. The beach’s size means you always find solitude, even during local festivals.
3. Mandorak Beach
A hidden gem accessible only via a forested trail or on horseback. This secluded crescent of white sand is framed by towering limestone cliffs and crystal-clear turquoise water. The effort to reach Mandorak is rewarded with one of Sumba’s most pristine and private beaches.
4. Waikelo Beach
Where a freshwater river meets the ocean, creating natural pools and a unique swimming environment. Convenient to reach from Tambolaka Airport, Waikelo combines accessibility with genuine beauty. Excellent for beach horse riding with the added drama of river crossing.
5. Weekuri Beach and Lagoon
A stunning saltwater lagoon formed by underground springs, connected to the ocean through limestone caves. The crystal-clear turquoise pool is surrounded by limestone cliffs and is one of Sumba’s most photographed locations. Swimming here feels like floating in a natural infinity pool.
6. Ratenggaro Beach
Below the famous Ratenggaro traditional village, this beach combines natural beauty with cultural significance. Dramatic rocks, clean sand, and views up to the clifftop village make this a unique combination of beach and culture. The beach serves as a Pasola ceremony ground during festival season.
7. Marosi Beach
A surf-famous beach known for its consistent right-hand break and beautiful setting. Even non-surfers enjoy Marosi for its dramatic coastal scenery, rocky headlands, and relatively easy access from the main West Sumba road. The surrounding grasslands provide excellent trail riding opportunities.
East Sumba Beaches
8. Tarimbang Bay
A sweeping crescent bay that is our primary location for horse swimming experiences. Protected waters, gentle sandy bottom, and coconut palm-lined shores create an idyllic tropical setting. The remote location means you will likely have the bay entirely to yourself.
9. Walakiri Beach
Famous for its iconic mangrove trees that emerge dramatically from tidal flats. During low tide, the expansive sandy flats create an otherworldly landscape perfect for horseback photography. Walakiri at sunset is one of Sumba’s most magical scenes.
10. Kerewei Beach
A remote eastern beach combining golden sand with dramatic rock formations. The surrounding reef creates calm lagoon conditions ideal for swimming and snorkeling. Access through East Sumba’s grasslands makes the journey an adventure in itself.
11. Londa Lima Beach
A hidden beach on the northeast coast, known for its pink-tinged sand — a result of crushed red coral mixing with white sand. The coloring is most visible in morning light and after rain. Snorkeling along the fringing reef reveals excellent coral and tropical fish diversity.
12. Puru Kambera Beach
A dramatic savanna landscape meets the ocean at Puru Kambera, where golden grasslands tumble down to a beautiful coastline. The combination of savanna, rocky outcrops, and turquoise water creates a landscape that could be Africa meeting the Caribbean. Excellent for photography and horseback exploration.
South Coast Gems
13. Watu Maladong Beach
A rocky beach near traditional villages, known for its dramatic stone formations and powerful surf. While not ideal for swimming, the coastal scenery is extraordinary and the surrounding area offers excellent cultural experiences combined with coastal trail riding.
14. Kalala Beach
A turquoise paradise on the south coast, Kalala features calm, shallow waters protected by an outer reef — making it ideal for swimming and snorkeling. The beach is relatively accessible but remains uncrowded due to Sumba’s overall low tourist numbers.
15. Bwanna Beach
One of Sumba’s most remote beaches, Bwanna requires significant effort to reach but rewards with absolute solitude and pristine beauty. The surrounding wilderness and total absence of development create a Robinson Crusoe atmosphere that adventurous travelers crave.
