12. Colombia's "Ciudad Perdida" Trek: Journey to the Lost City

For adventurous retirees with good fitness, the trek to Ciudad Perdida (The Lost City) in Colombia’s Sierra Nevada mountains is an unforgettable endeavor. This challenging multi-day hike through lush jungle, crossing rivers and interacting with Indigenous Wiwa communities, culminates in the discovery of ancient Tayrona ruins predating Machu Picchu. It's a journey back in time, offering breathtaking scenery, rich cultural encounters, and a profound sense of accomplishment. Far more rugged and less commercialized than Peru's famous Inca trail, it’s a true adventure for the intrepid soul.
