Last month I was travelling through the Philippines. We spent 5 days visiting a friend on the Island of Siargao, famous for its surfing break Cloud 9, and relatively unknown otherwise (for now). He took us around to all the cool things he’s discovered on the island, including a set of water caves a few hours away by boat. Apparently we lucked out with our timing, because the caves were nothing compared to what was going on in a nearby cove. I guess it’s seasonal, but every year a nearby protected lagoon becomes a breeding ground for jellyfish.
