Ancient Karthea on the island of Tzia is a historical site that offers a glimpse into the rich past of this region. 

Visitors can explore the remnants of temples, stadiums, and residential buildings, all set against a backdrop of stunning natural beauty and there is also the option of dropping by the non-organised beach nearby. 

The site is accessible through a downhill trail which takes around 25 minutes to hike and around 45 minutes to ascend when returning, so visitors should bring trainers as well as food and water.
