There is more to the area than boats. Easy half-day trips from town reach the Batu Cermin cave, the Cunca Wulang canyon and waterfall, where you can swim in clear pools, and Melo village for caci dance performances and views over the coast. Rangko cave, reached by a short boat ride, has a saltwater pool lit by the sun.
For a deeper look at Flores, overland tours head east through Ruteng and Bajawa to the coloured lakes of Kelimutu, and the trek to Wae Rebo village is one of the most memorable experiences in Indonesia. This page lists tour companies, local guides, cooking classes and activity operators.
