There are so many lakes in the world and it's hard to imagine that some are beautiful lakes you don't want to swim in. A lake brings to mind cool water, tree lined fringes, maybe a day spent relaxing on a boat. You might like to fish or water ski. You might just enjoy the scenery – shimmering in summer and glisteningly frosty in winter. You might like to take a dip. Sounds idyllic yes? Well not in these lakes! Check out this list of lakes you wouldn't want to swim in.
1. Jellyfish Lake, Palau
The Rock Islands archipelago boasts some 70 weird lakes, but Jellyfish Lake on Eil Malk Island in Palau takes first prize in weirdness. It is home to millions of golden jellyfish. They migrate horizontally across the lake every day, providing visitors with a spectacular sight. Golden Jellyfish (Mastigias cf. papua etpisoni) and other marine species living in the lake have evolved quite differently from their nearest relatives residing in neighboring lagoons because Jellyfish Lake on Eil Malk Island is so isolated.
