Jellyfish Lake (snorkel only, no scuba)
Scuba diving is banned in Jellyfish Lake (Ongeim'l Tketau) on Eil Malk – it is a snorkelling site only. The lake was closed to visitors from 2016 after the golden jellyfish population collapsed and reopened in 2019; as of 2025 reports it is open, with fewer golden jellyfish than in the past.
