Pamukkale Thermal Pools, Denizli Province, Türkiye The name Pamukkale translates to ‘cotton castle’ in Turkish, which is fitting given the white, cotton-like appearance of the travertine terraces that form these thermal pools. There are 17 hot water springs in Pamukkale, with temperatures ranging from 40F to 210F. The calcite-laden water is said to have healing properties thanks to its high mineral content. The ancient city of Hierapolis where the pools are located is a UNESCO World Heritage Site and a bucket-list destination for all ages. In addition to the thermal pools, visitors can also explore the ruins of Hierapolis, including the Temple of Apollo, the Roman theater and the Necropolis.

Poça da Dona Beija Hot Springs, Azores, Portugal On the island of Sao Miguel, the largest in the Atlantic archipelago of the Azores, a visit to Poça da Dona Beija means relaxation and recuperation in bubbling hot springs set against a lush subtropical backdrop. The series of five pools range from 80F to 100F and are popular spots, so the best time for a quiet soak is usually early in the morning. They are open until 11pm, so guests can indulge in an atmospheric nighttime swim too. Travelers can also dip a toe in the famous orange river — the color is caused by high iron levels in the water, and locals swear by its healing properties. For those seeking tranquility, Poça da Dona Beija will leave both body and mind refreshed.
