Where is Mt Olympus in The Lightning Thief?

In Rick Riordan's *The Lightning Thief*, Mount Olympus is not a physical location. It's the home of the Greek gods, residing in the sky, accessible only by climbing a magical staircase or flying.

While the novel mentions the location as being "high above the clouds", it never specifies a precise geographical location. It's more of a metaphorical place, representing the realm of the gods and their power.
