After breakfast this morning, travel to the town of Pamukkale. Named after its incredible travertine terraces, Pamukkale means ‘cotton castle.’ This spectacular natural phenomenon was created by deposits from thermal waters that cascaded down the mountainside over hundreds of years, forming a collection of pools and terraces. As the water overflows, dazzling cream-coloured stalactites are formed that, from afar, resemble cotton or snow. The pools are filled with waters that many believe have healing properties for circulation and the digestive system. Head up to the ruins of Hierapolis – an important Roman bath centre founded by the King of Pergamon in 190 BC, where your leader will bring history to life and guide you through an ancient temple, holy area, monumental fountain, bath, basilica, necropolis and an impressive theatre. You then have the evening free to spend how you wish.
