Alto de Letras (The King of Mountain Climbs)

The mythical climb of South America. Rising over 10,400 vertical feet continuously across 50 miles, Alto de Letras is the longest continuous mountain climb on the planet. Begins in the stifling 90°F heat of the Magdalena River Valley at Mariquita and summits at a freezing 12,096 feet in the windswept volcanic páramo of Nevado del Ruiz, before descending into the coffee plantations of Manizales.
