Alto de Letras, Mountain pass in central Andes, Colombia.
Alto de Letras is a mountain pass in the central Andes that straddles the boundary between Tolima and Caldas departments. The road climbs through rugged terrain, connecting the valleys on either side as it gains elevation steadily.
The passage grew from a simple footpath into a paved road connecting Mariquita and Manizales over time. This upgrade transformed how people and goods moved between the regions on either side.
Mountain communities here depend on farming, growing crops suited to different elevations as they move up the slopes. People follow farming traditions passed down through generations, adapting what they grow to each zone's climate.
Visitors should prepare for significant elevation gain and bring both warm and light clothing since temperatures drop sharply as you climb. The ascent is long and demanding, so good physical preparation matters.
The route presents cyclists with one of the world's longest continuous climbs, making it a rare testing ground for endurance. The ascent challenges riders over an extended stretch without significant breaks.
