FOG
The white city of the Yucatan

Walk Merida along the Paseo de Montejo

Merida is the capital of the Yucatan, a colonial city of pastel houses, a big plaza and a grand boulevard of mansions. FOG keeps the map dark until you walk it, and its regular grid lights up block by block.

The centre

The Plaza Grande is surrounded by the cathedral, one of the oldest on the American mainland, the Casa de Montejo with its carved facade, and the government palace with large murals. The streets around it form a grid, numbered rather than named, even to the north and odd to the east.

Old barrios such as Santa Lucia, Santa Ana and Santiago each have their own plaza and church.

The Paseo de Montejo

The Paseo de Montejo is a broad boulevard north of the centre, lined with mansions built during the henequen boom. Walk its length and back for a long straight line.

On Sunday mornings, some central streets close to cars for walkers and cyclists, and the Plaza Grande holds a market. In the evenings, the plazas host music and dancing.

Heat

Merida is very hot, especially from April to June. Walk early in the morning and in the evening. Winter is the most comfortable time.

The numbered grid fills cleanly, and keeping track of which numbers you have walked becomes a game in itself.

How FOG keeps score here

FOG starts with the whole world under fog. Every place you physically walk clears a circle of roughly 120 metres around you, and that ground stays clear for good. It keeps working with the app closed and the screen off once you allow background location, so the walk to dinner counts as much as the planned loop.

There is no account, no sign-up and no cloud. The trail lives on your phone and nowhere else, and you can export a GPX backup whenever you like. Exploring is free; one purchase of FOG Unlimited adds the higher ranks, all five character paths and history import, with no subscription.
