Ischia

Ischia’s volcanic hot springs offer a wellness retreat with 29 thermal parks fed by Monte Epomeo’s geothermal activity at temperatures up to 100°C, 40% hotter than the average thermal source in Sardinia. The island covers 46 square kilometers with lush gardens like the Giardini La Mortella, a 2-hectare botanical paradise featuring 1,000 plant species from five continents. Ischia receives 70% fewer tourists annually than neighboring #3 Capri, allowing for a 25% lower cost per hotel night while providing superior thermal amenities. Its Aragonese Castle, built on a volcanic islet and linked by a 220-meter causeway, dates to 474 BCE, predating Capri’s Roman villas by 300 years. This offers a quieter, more affordable alternative with a rich geological and historical depth.
