Ciudad Perdida, also known as the "Lost City," is an ancient archaeological site located in the Sierra Nevada de Santa Marta mountains in northern Colombia. It is believed to have been built by the Tairona civilization between the 8th and 14th centuries, long before the arrival of the Spanish conquistadors.
The Lost City was discovered by a group of treasure hunters in the 1970s, and since then it has been gradually restored and opened to the public. Visitors can hike through the dense jungle to reach the site, which consists of a series of terraces and staircases carved into the mountainside. The ruins are thought to have once been a thriving city with a large population, although much of the site is still overgrown with vegetation.
The hike to Ciudad Perdida is a challenging but rewarding experience, with beautiful scenery along the way and a chance to learn about the history and culture of the indigenous people who once inhabited the region. It typically takes four to six days to complete the trek, and visitors are advised to go with a licensed guide and to be in good physical condition.
