After a pickup from your Kusadasi hotel, head to Denizli Province to visit Pamukkale –Turkey’s most incredible natural wonder. Meaning ‘cotton castle,’ this stunning UNESCO World Heritage Site consists of dazzling white travertine rock terraces that seem to flow down 656-foot (200-meter) cliffs. From a distance, the travertine terraces almost look like snowy cliffs or frozen waterfalls, but in fact they are mineral deposits from Pamukkale’s hot springs. Walk around these fascinating rocks and see the naturally formed bathing pools while learning about their geology from your guide. Views from Pamukkale are unforgettable – see the white travertine terraces contrasting with brown mountains in the distance, and then walk up to Hierapolis, the ancient Greco-Roman city with crumbling ruins and geothermic bathing pools. Enjoy time at leisure here, and be sure to bring your bathing suit as the pools are definitely worth a dip (entrance fee is at your own expense)!
