The Red Sea has a seriously long list of underwater celebs – and we’re not talking about Nemo. You’ll find the fire engine-red Hurghada Star, the polka-dotted coral grouper and the egg yolk-yellow thorny seahorse. Ancient-looking giant turtles and moray eels cruise the warm waters, too. For a close-up without the snorkel, a glass-bottomed boat is the answer. Their transparent hulls give you a window to the reefs without getting wet.
