Hotels often have the biggest pools, and sometimes an indoor pool in the spa as well. In Fira and Imerovigli, you stay on the rim of the caldera, with the volcano opposite. Here are the 32 hotels I've selected in Fira, all rated at least 8/10; I particularly recommend Andronis Concept Wellness Resort, Santorini Princess Presidential Suites and Radisson Blu Zaffron Resort, Santorini.
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.
