Parkour's entire map is divided into a couple districts, each with their own spawn for users to discover. It's purpose is to ease the travel time a user might take when they want to free run in a certain part of the map.
They're identified by the red glass windows and light grey metal pillars, with some sites even having a climbable crane.
Here are all of the spawns and where they are.
The regular spawn where nearly every player spawns in. Do you even need a picture of it?

Northern Site Edit
The Northern Site is near Crest Tower and is not near the NORTH sign, despite its name.
Crest Site EditThe Crest Site is very close to a zip line that leads to Crest Tower, which is the highest point in the game.
Vertex Site EditThe Vertex Site is next to a building that contains the Vertex Tower time trial and a zipline that leads to Vertex Tower.
The Office Site is North of the South sign, which is the direction the block on the crane at spawn is going. If you go on top of the building straight ahead from the block on the spawn crane, it is easy to see.
