Sumba Island The river and waterfall in the midst of nature are refreshing.

Sumba Island in Indonesia offers a delightful spot. It's located deep in the mountains, and you need a local to take you there by motorbike. It took about 3 hours from the main area. The cold water and beautiful nature were incredibly refreshing. I want to go again with a swimsuit and sandals. Getting around Sumba Island is difficult without a car or motorbike. Some roads are not well-maintained, so it's recommended to join a tour.
