Yes, certain areas in Athens would be better for walk-ability than others depending on your needs and budget. I would take a look at the ARMC, Normal town area near Oglethorpe. Zillow gives ratings for walk-ability for your consideration as well..... look for the "walk score" underneath the map on listings.
I hope this helps.
Let me know if I may able to assist you further in your potential house hunt.
