Hiking from Bitola to Ioannina (Skopje)

Hello, I am looking to go hiking sometime in May with my Dog. Does anybody know of any good trails or websites for trail searching? Everything I've found is more catered towards hiking in the U.S.A.

Any resources, and or personal experiences would be greatly appreciated.

I don't always check internations so feel free to message me on WhatsApp or SMS: Protected content

Thank you!
