Hawang Freshwater Cave is one of the easiest inland excursions on Kei Kecil, a clear pool tucked into limestone and shaded by trees. After the open glare of the Kei beaches, the cave feels cool and still, with blue-green water and rock formations that make it more than just a swimming hole.
Local stories add to the visit, but the practical appeal is simple: a short trip, a swim, and a different texture of island landscape. Go with someone local or a driver who knows the access, and keep the visit low-impact; small freshwater sites suffer quickly when they are treated like beach clubs.
