Your Catania policy should address the region's specific challenges. If you're visiting during summer, ensure coverage for heat-related illnesses, as heat waves present a moderate risk. Winter travelers planning alpine skiing need explicit winter sports coverage, as skiing and snowboarding accidents are a moderate concern and standard policies often exclude these activities. For mountaineering enthusiasts, high-altitude rescue coverage is recommended given the terrain. If you're planning to scuba dive in Sicily's waters, verify your policy covers decompression chamber treatment specifically. Volcanic activity near Mount Etna poses low but year-round risk, so confirm your policy doesn't exclude natural phenomena. Most importantly, ensure robust repatriation coverage since EHIC won't cover transport home, and medical evacuation from mountain areas can require expensive helicopter services.
