Questions about the world

[Sage]

How big is it? How open is it? Is there a map available to view?

From the planet:
"
The planet Golarion orbits a yellow sun in the far reaches of the Material Plane. Third of eleven in orbit, this blue planet contains vast oceans and lush green lands, the perfect environment for countless cultures to thrive. Indeed, Golarion is the most populous planet in its solar system. Golarion's crater-scarred moon, Somal, fills its night sky, and its nearest planetary neighbors, Castrovel the Green World and Akiton the Red Planet (second and fourth from the sun, respectively), are easily visible as colored stars.

Due to its innately hospitable and life-sustaining environment compared to other worlds, presumably the work of the gods, astronomers sometimes refer to Golarion as "the Child". Astronomers on other planets, however, often refer to Golarion as "the Cage" in reference to its cosmic role as the prison of the mad god Rovagug, who lies bound at the world's core."

Thank you, but I'm asking specifically about the in-game world.

You're not going to be able to explore all of Golarion.

And because you seem to be really interested from game and world here is bit more info from the Stolen Lands (where game is set from most part):

History

The nation of Taldor made the first major attempt to tame the lands now known as the Stolen Lands. The way was paved by the Fifth Army of Exploration, which made considerable attempts to map and explore the River Kingdoms. The effort was eventually for naught and various ruins and abandoned mines can still be found throughout the Stolen Lands to this day.

Other attempts have been made from various factions over the centuries, whether by Brevoy or nations of the River Kingdoms. Despite the fact that no nation can hold the Stolen Lands for long, the attempts of colonization has caused considerable consternation between all parties.

The most recent attempt came in 4710 AR. King Noleski Surtova sent explorers and settlers to explore and ultimately settle the Stolen Lands.

There is no clear reason why the Stolen Lands has proven so difficult to settle over the centuries but scholars have noted that the barrier between the Material Plane and the First World are unusually thin in the region. Some theorize that this connection has made the area difficult to tame.
