Riding Time: Mountain Biking Medellín’s Forgotten Railways to Amagá
Half-day mountain biking from Medellín into Amagá—tunnels, iron viaducts, and cloud-forest singletrack
You start by hearing metal before you see it: the far-off clank of a century-old bridge flexing under wind and the distant echo of a tunnel mouth—dark, low, and perfectly circular—waiting like a secret. The trail out of Medellín slips from city humidity into cloud-soft forest, and within an hour you’re on a dirt shoulder where rails used to lie. When you push off and pedal, the landscape opens: corrugated cliffs, a string of waterfalls, and iron viaducts 260 feet above the valley floor that make your chest tighten in the best way. This is not a race; it’s a slow unspooling of history and geology under your tires.
Trail Wisdom
Do a pre-ride bike check
Inspect brakes, tire pressure, and quick-release levers—riding through tunnels and technical descents demands reliable stopping power.
Helmet and lights for tunnels
A snug helmet is mandatory; a handlebar or helmet light is useful for dark tunnel passages even on daytime rides.
Hydrate and eat before the last climb
Carry at least 1–1.5 liters of water and a compact snack—there are no consistent services on the route.
Choose the right tire pressure
Lower pressure improves traction on wet roots and rocks but beware pinch flats; 28–32 psi (front) and 30–35 psi (rear) is a common compromise for 2.2"–2.4" tires.

Conservation Note
Stick to the established trail, pack out all trash, and support guides and local businesses who use tourism income for trail maintenance and habitat protection.
The Ferrocarril de Antioquia was a critical 19th–20th century rail network that linked Medellín with southwest towns—these tracks shaped the region’s industry and migration.
Seasonal Guide
spring
Best for: Lush cloud-forest scenery, Fewer tourists
Challenges: Increased rain and muddy trails, Slippery tunnel entrances
Spring (Mar–May) tends to bring more showers; trails are green and dramatic but can be slick—plan an early start and expect damp conditions.
summer
Best for: Drier trails, Clearer views
Challenges: Hotter midday temperatures, Higher demand for tours
Summer (Jun–Aug) is generally drier and offers the most reliable riding conditions; morning departures are ideal to beat heat and afternoon storms.
fall
Best for: Vibrant vegetation, Fewer crowds
Challenges: Return of seasonal rains, Some route sections may be closed after heavy storms
Fall (Sep–Nov) cycles back into wetter weather—expect muddy stretches and possible reroutes after heavy rain.
winter
Best for: Cooler temperatures, Crisp morning light
Challenges: Intermittent rain depending on year, Chilly early starts
Winter (Dec–Feb) often brings clearer skies and cool mornings; pack a light shell for early humidity and higher-elevation chill.

Active beginners with some off-road experience can join, but expect technical sections; consider mentioning your skill level when booking so guides can adjust the pace.
What should I do if it rains?
Expect wet, slippery conditions; slow down on roots and rocks, use lower tire pressure for traction, and follow your guide’s advice—some operators will alter the route in heavy rain.
Is there a restroom or food stop on the route?
Services are limited on the trail itself; operators typically include a short stop in a town or at a local farm where you can buy snacks or use basic facilities.
