Insider Tips from Our Local Guides
Our experienced Sumba guides recommend several lesser-known activities for this month. Visit the local morning markets that operate in different villages on rotating days — each market offers unique textiles, spices, and traditional medicines. Ask your guide about the ceremonial calendar, as many traditional rituals and village ceremonies happen throughout the year beyond the famous Pasola. Photography enthusiasts should bring a drone (check regulations first) as Sumba’s landscapes are extraordinarily photogenic from above. For the best local food experience, request a traditional Sumbanese cooking class at your resort or arrange a village home-cooked meal through your guide. Birdwatching is excellent year-round with over 250 species including several Sumba endemics like the Sumba Hornbill and Sumba Buttonquail. Consider dedicating one morning to a guided birding walk through the forest near your accommodation.
