Walk Nice and the coast lights up first
FOG covers the whole world in fog. Every street you physically walk in Nice is revealed permanently, and the map never leaves your phone.
Three cities in one
Nice is built in layers that walk completely differently. Along the water is the Promenade des Anglais, about seven kilometres of unbroken seafront from the airport end round the Baie des Anges to the Quai des États-Unis. It is flat, wide and impossible to get lost on.
Behind the eastern end is Vieux Nice, a knot of medieval lanes barely wide enough for two people, opening at Cours Saleya where the flower market is and at Place Rossetti. Rue Droite and Rue Benoît Bunico are typical: dark, tall, and about three metres across. North and west of that is the nineteenth century town, a proper rectangular grid around Avenue Jean Médecin and Place Masséna, with the Promenade du Paillon running through it as a green strip where the river used to be. Then the hills: the Colline du Château above the port, Cimiez behind, and Mont Boron to the east.
The route to do first
Start at Port Lympia and climb the steps up the Colline du Château. From the top you can see the whole bay, which is a useful preview of the stripe you are about to walk. Come down the west side straight into Vieux Nice and spend an hour just threading the lanes, because they are short and there are dozens of them.
Come out at Cours Saleya, cross to Place Masséna, then follow the Promenade du Paillon inland past the fountains and back. Finish by dropping to the seafront and walking the Promenade des Anglais west for as long as you feel like. That is a compact loop and it covers the three most distinct kinds of ground the city has.
Easy start, slow finish
The first days here are quick. Vieux Nice is tiny and packed with lanes, so it turns solid on the map faster than you expect, and the grid around Jean Médecin is regular enough to sweep street by street. The Promenade is satisfying but it is worth being clear about what it is: one very long line. It adds distance and almost no width.
The real work is uphill. Cimiez climbs steeply on switchbacks, and Mont Boron and the Fabron slopes are full of private villa lanes and dead ends that you have to walk in and back out of. That is where the percentage stops moving quickly. One practical note on Vieux Nice: the lanes are narrow and the buildings are high, so the trace can drift onto the next street over. Walking a lane twice usually sorts it. Weather is rarely the obstacle here, with mild winters and a long walking season either side of the hot summer.
What FOG does
FOG is a fog of war walking map. The whole world starts hidden. Only the streets you physically walk are revealed, and they stay revealed. Background exploring keeps working with the app closed and the screen off, so a stroll to the market still counts.

Questions people actually ask
Does the Promenade des Anglais fill much of the map?
It adds a long line but very little width. The old town lanes and the grid streets are where the area comes from.
Why does my track wander in Vieux Nice?
Narrow lanes between tall buildings make phone GPS bounce. It is normal in old town cores, and a second pass usually tidies the line.
Can I import a past holiday here?
Yes. History import is included in the USD 5.99 unlock and reads Google Timeline exports and GPX files.
Does riding count?
Yes. FOG works for walking, running and riding, anywhere on Earth, so the seafront cycle path reveals the same way.
