This all-encompassing itinerary combines Colombia's popular attractions with some roads less traveled. You'll begin your journey in the "city of the eternal spring," Medellín, and visit El Peñon de Guatape, a landmark granite rock jutting hundreds of feet out of the ground. If you're a caffeine lover, get ready to visit Colombia's mountainous Coffee Region. You'll embark from this area and hike, mountain bike, and birdwatch through the adjacent sub-Andean forests. Next it's off to the indigenous archeological site of Tierradentro, with its ancient underground burial chambers. Learn about the civilization who built them, then end your stay in the southern colonial town of Popayán.
