Kakaban Jellyfish Lake

A landlocked brackish lake in the middle of Kakaban island, reached on foot by boardwalk from the jetty. Entry has been charged at around IDR 100,000 per person. Sources published in 2025 and 2026 disagree on whether swimming is currently allowed or whether visitors view from the boardwalk only, so confirm with your operator rather than planning a trip around it.
