I have two entries into the “hidden” list, both oddly enough within 10 minutes of one another.
Chattahoochee Golf Club (Gainesville): Typically right about $30 to walk, home of Masters Champion Tommy Aaron. Course feels a little bit like the UGA course in Athens but a little easier on the scorecard. Awesome greens, fun layout. From what I understand they have a membership with several old dudes hitting low single digit handicaps. Owned now by the city - great muni!
Chicopee Woods Golf Course (Gainesville): Also right around $30 to walk - has 27 holes each with their own “flavor”. Love the little starter shack to direct golfers where to go. Another great layout with awesome greens - a bit more elevation change that Chattahoochee.
Can’t recommend these two courses highly enough! I drive an hour to play these over closer options charging 2-3 times the fee.
