Milos also has Sarakiniko's lunar white rock shelf and Papafragas' slot canyons. Kleftiko means 'thieves' place', it was a pirate hideout, and the caves were used to hide ships. Milos supplied obsidian across the Neolithic Mediterranean and later mined sulphur and bentonite; the Venus de Milo was found here in 1820. Anchorage: Kleftiko is fully exposed to the west and unusable in a meltemi swell. Adamas and Provatas offer shelter. Hazards: No site-specific hazards noted, brief normally. Plus
