This large, shallow lake is fringed by wetlands, with floating houses and magnificent birdlife. Hotels can help you charter a boat (160,000Rp for two hours), allowing you to speed along Sungai Walanae, visit Salotangah village in the middle of the lake, cross to Batu Batu village on the other side, and return within the two hours. You could haggle for a cheaper rate at the longboat terminal opposite the sports field on Jl Sudirman.
Geologists believe the lake was once a gulf between southern Toraja and the rest of South Sulawesi. As the lands merged, the gulf disappeared, and geologists believe the lake will eventually disappear too.
