Walk Quito and light up the long valley
FOG hides the entire world map and reveals it only where you have physically walked. Quito is long, thin and high, so the revealed map here ends up as a narrow stripe running north to south between the mountains.
A city fifty kilometres long and barely any wide
Quito is wedged into a valley on the flank of Pichincha, with the volcano on one side and a drop into ravines on the other. The result is a city that runs roughly fifty kilometres north to south and only a few kilometres across at most points. The main avenues, 10 de Agosto, Amazonas, 6 de Diciembre, all run the long way because there is no other direction to run.
The Centro Historico in the south is one of the largest and best preserved colonial cores in the Americas. Plaza Grande, the long straight of Calle Garcia Moreno, the enormous plaza in front of San Francisco, the Basilica del Voto Nacional up on its ridge. The grid there was laid on top of hills, so a straight street can drop and climb again twice in four blocks.
North of that is modern Quito: La Mariscal around Plaza Foch, the green rectangle of Parque La Carolina, and the office towers along Naciones Unidas.
A day in the old centre
Start at the Basilica, walk south down Garcia Moreno through Plaza Grande, then out to Plaza San Francisco and down to La Ronda, the restored lane in the ravine at the bottom. Climb back up and, if your legs are willing, continue to El Panecillo, the hill with the winged Virgin standing on it, which gives you the entire old town below and the valley running away north.
That is only five or six kilometres, but at this altitude it walks like ten and the climbs are real. On the map it fills the colonial grid solidly, which is the densest and most satisfying block of the city.
Another good half day: Parque El Ejido north through La Mariscal to Parque La Carolina, then east and down the hill to Guapulo, an old village stacked on a steep slope below the modern city. Going down is easy. Coming back up is the altitude reminding you where you are.
Altitude, rain and a stripe on the map
Two things shape walking here. The first is 2,850 metres. For the first three or four days a moderate hill will stop you, and it is not fitness, it is oxygen. Take the first days flat and slow. The second is the geometry. Because the city is a ribbon, your revealed map grows as a long narrow band rather than a spreading blot, and city percent moves slowly because the municipal area includes a great deal of hillside you are never going to walk.
Weather is equatorial and steady rather than seasonal: cool because of the altitude, bright mornings, and rain that tends to arrive in the afternoon between roughly October and May. Sun at this height burns fast even when the air is cold.
Sensible practice matters too. Stick to busy streets and daylight, particularly in and around La Mariscal and the quieter edges of the old centre after dark.
How FOG works
Everything starts hidden. Streets clear as you physically walk, run or ride them, and they stay clear permanently. Being nearby does not count.
There is no account, no sign-up, no cloud, no analytics, no ads and no tracking. The map never leaves the phone, and you can export your data. Background exploring keeps revealing with the app closed and the screen off, which is what you want if you would rather not have a phone out on the street.
Exploring is free. One purchase of USD 5.99, with no subscription ever, unlocks unlimited ranks, every character and history import from Google Timeline exports and GPX files. Ranks rise with area covered: Wanderer, Scout, Pathfinder, Explorer, Voyager. The collection covers 241 countries, 3,390 regions and 7,342 named places, all earned by standing in them. For any city you have walked, FOG shows what percentage of it you have lit.
Questions people actually ask
Does the altitude change how you should plan walks?
Yes. At 2,850 metres, hills that would be trivial at sea level are not, especially in the first few days. Start with flat routes like Parque La Carolina and build up to the old town climbs.
Why does Quito fill in as a stripe?
The city is roughly fifty kilometres long and only a few wide, hemmed in by the volcano and the ravines, so walked routes stack into a narrow north-south band.
Which area is most rewarding to cover?
The Centro Historico. The colonial grid is dense and continuous, so a single day of deliberate walking clears a large, tidy block of map.
Do I need a data connection for the app to work?
No. There is no account and no cloud. Revealing happens on the phone and the map stays there.
Can I import old walks?
With the paid unlock, yes. FOG imports Google Timeline exports and GPX files.
