Twin Lakes is a Fairfax County Park system course south of I-66 between Centerville Road and the Fairfax County Parkway.

There's two completely different golf courses here designed and redesigned by Denis Griffiths. The Oaks Course is parkland style layout carved through the oak trees. It's slightly longer and a shot maker's layout with narrow fairways, 56 sand traps, seven water hazards, and small, well protected greens. There's four sets of tees, the tips play to 6,715 yards, 76.3/137, course/slope ratings.

The Lakes Course is the original layout and is more open off the tee with a scattering of trees along the fairways and a couple of lakes to navigate. From the tips, it plays to 6,695 yards, 72.1/126, course/slope ratings with three shorter tees.
