I visited Prailiu as a solo traveler interested in learning more about Sumba cloth and ikat weaving, and I got to experience all of that plus more. The hospitality and kindness of the the people is really beyond. As a weaver it was also fascinating to see how the ikats are made, right outside all of the houses. As you walk around, you'll see women weaving at their doorsteps and children playing. It was also fun to learn about the traditional architecture, the history of the traditional villages like Praliu, and spiritual beliefs and rituals.
I ended up spending an entire week there, and took some day trips from Waingapu/Prailiu.
This is definitely a bit off the regular international tourist path, so those who are interested in that will love it. Nearby beaches were also spectacular, and nobody else was even around. I hope to be able to visit Sumba again!
