Walking the USA

A walk in Half Moon Bay

Main Street is five walkable blocks, and the Coastal Trail runs the bluff separately for miles. A coastside farming town of about 12,000 hosts a free pumpkin festival that draws a crowd many times its size, then settles into fog season.

On the map

FOG: Fog of War Walking Map starts with Half Moon Bay under fog and clears it only where you physically walk. In a town this size the downtown comes out of the dark in whole blocks in an afternoon, and it stays cleared. No start button, no workout to end: it runs with the app closed and the screen off, and it needs no signal.

Somewhere to eat afterwards is on the Half Moon Bay festival page.
