About 500m past Kafeneion Ta Therma, a lush wooded path (100m) leads to a series of rock pools and waterfalls, the most impressive being 30m in height. This is gorgeous, Lord of the Rings –like terrain, where gnarled, 600-year-old plane trees covered in moss loom out of fog over a forest floor of giant ferns and brackish boulders. Get ready for an ice-cold dip on a hot summer day.
