Im not the big expert, but i would say no. Pathwalking is shamanistic. I wouldnt categorize Greek traditions that way.
The closest thing i can think of to this might be the way oracles operated receiving visions. but there again, thats different then what i think you mean.
Alot of greek mythology...stories ...could be perceived as examples of pathwalking as the hero goes on a kind of mystical journey...the story of Theseus in the Maze of the Minotaur. But hten thats really abstract, and maybe too much so for what youre asking?
