Lesvos has a number of hidden waterfalls - or katarachtes - dotted throughout the island. The best way to reach these is by talking with Sappho Travel, which can arrange a day trip. Some of the waterfalls are suitable for swimming and home to a variety of local wildlife like turtles, frogs, crabs and migratory birds. A few of them also have a small cafe or taverna for an after-swim lunch.
