Take the following as truth: Excursions further up the mountain take you to two medieval fortresses, on foot to Cetello di Taormina and, by car along a winding road, to Cetelmola, for grand views, although the summit of Etna is almost always swathed in clouds.
Then the following statement: "There are no excursions up into the mountain worth taking." is true, false, or inconclusive?
