Is Santorini dangerous? 8 hazards to know
Santorini is a caldera rim with a village built along its edge, which makes its central hazard structural: steep steps, low walls, crowded viewpoints and a long drop. Rented ATVs on narrow gravelly roads are the other consistent source of tourist injury. Seismic swarms occur and can shake rock loose from the cliffs, but rarely disrupt a visit.
