Take Porters Creek Trail, a gravel road alongside Porters Creek. You will pass by an old farmstead and cemetery, as well as lots of wildflowers if you're out during the spring.

In a mile, keep left, then in another half mile or so you should cross over a small (and somewhat harrowing) footbridge. The 40-ft tall Fern Branch Falls is less crowded than other falls in the park, and has open access year-round.
