So you've heard about this place but not sure how to get there, let me show you the way.
We will start at Orpheus Way

And end up at Orpheus' Cave.

You will only need to do this once to add it to your tp list. Orpheus Cave is the ONLY tp connected to Ancient Greece. But you can now tp directly to Next Island's Orpheus' Cave (you couldn't do this before.)
