Fira, perched on the caldera cliffs of Santorini, offers a surprisingly diverse array of spa and hot springs experiences. While many visitors focus on the stunning views or the iconic sunsets, the island’s volcanic activity also means natural thermal waters and scenic boat trips are just around the corner. We particularly like the chance to combine a boat trip with a soak in warm volcanic waters—imagine swimming in a natural hot spring while overlooking the Aegean. Of the options listed, the trip that includes hiking up an active volcano and relaxing in thermal waters really stands out for its balance of adventure and relaxation.
Santorini’s volcanic landscape lends itself perfectly to hot springs and volcanic hikes, making these experiences unique compared to traditional spa visits. Whether you want a quick dip or an active day exploring craters and villages, there’s something for all. Below, we introduce three highly-rated tours that showcase different ways to indulge in Santorini’s geothermal and scenic riches.
