Fog of war, Aburra valley

Walking Medellin with the map switched off

FOG starts with the entire world under fog, Medellin included. The only way to clear it is to physically walk the streets, which in this city means picking your side of the valley first.

The valley decides the walk

Medellin is built into the Aburra valley, and the shape of that valley controls everything about walking here. The floor, where the Medellin River and the overhead metro run, is flat and long. The sides go up hard. That single fact splits the city into two very different walking experiences.

Laureles is the flat one. It is a loose radial grid of low buildings, shade trees and roundabouts, and you can cover a lot of it without ever gaining serious elevation. El Poblado is the opposite. Streets like the climb up from Avenida El Poblado toward Provenza and Parque Lleras are steep enough that you feel them, and the further uphill you go the more the pavement narrows or disappears entirely. Comuna 13 goes further still, so far uphill that the city installed outdoor escalators to make it survivable.

Neither side is wrong. But if you want fog cleared per unit of effort, start flat.

An afternoon in La Candelaria

The downtown core gives you the densest fog clearing in the city. Start at Plaza Botero, with the fat bronze figures and the Museo de Antioquia on one side and the Palacio de la Cultura on the other. Walk out onto Avenida Carabobo, which is pedestrianised through the centre, and follow it north through the crowd and the street sellers to Plaza Cisneros, the square of tall light poles people call the Parque de las Luces.

From there you can cut back through Parque Berrio and up the Pasaje Junin toward Parque Bolivar and the enormous brick Metropolitan Cathedral. It is maybe three or four kilometres in total, on flat ground, through streets packed so tightly together that the fog comes off in a solid block rather than a thread.

What fills in fast and what does not

Medellin rewards a specific tactic. The valley floor fills as a stripe. Walk the river corridor, or ride the metro out and walk back, and you get a long bright band that reads clearly on the map but stays narrow. To get real area you have to go sideways into a neighbourhood grid.

Laureles is the best value in the city for that. It is flat, the blocks are short, and the streets connect, so an hour of wandering closes a lot of ground. El Poblado costs you far more effort for the same square metres because you are climbing the whole time and the streets curve back on themselves. The comunas on the upper slopes are the hardest of all, full of stairs, dead ends and alleys narrower than a car.

FOG shows you a city percent for anywhere you have walked, and in Medellin that number moves slowly. The metropolitan area is long. Treat it as a project rather than a weekend.

Practical notes

The altitude is about 1,500 metres, which is enough to notice on a climb but not enough to be a problem. The weather is the famous part. It is mild all year, which means there is no walking season and no off season, but rain arrives in the afternoon often enough that a morning walk is the safer plan.

Traffic is the real hazard rather than gradient. Sidewalks vanish, motorbikes use gaps, and crossings on the big avenues are not always where you want them.

FOG keeps recording with the phone in your pocket and the screen off, so you do not have to hold it out while you navigate a busy street. Nothing you walk is uploaded anywhere. The map stays on the phone.

Questions people actually ask

Where should I start if I want to clear a lot of fog quickly?

Laureles. It is flat, the blocks are short and the streets actually connect, so you cover far more ground per hour than you will on the slopes of El Poblado.

Does the altitude or the hills affect tracking?

No. FOG records the streets you physically walk, and the elevation makes no difference to that. The hills only affect how tired you are at the end.

Can I use the metro and cable cars between walks?

You can travel however you like, but only the parts you walk are revealed. Riding the metro out and walking back is a common way to cover the valley floor.

What does the paid unlock include?
