This is one of the many washing/swimming pool located on the road to Laluni. We saw a busy bunch of people on our way in and a few hours later while leaving the area we saw it like this (picture). Without seeing how it was before one might be scared take a plunge.
Black water is always scary, primarily because you are not able to confirm the presence of the creatures you may have imagined in your head.
