Martin's Creek Falls (sometimes referred to as Martin Creek Falls) is a beautiful waterfall (20 feet high) to visit if you're ever in the Erwin, TN area. It's located right outside of town, within the Cherokee National Forest. It's not very well known -- but what it lacks in terms of power and majesty, is made up for in peace and tranquility. It's worth a visit - especially after some heavy rains. In times of drought this waterfall is reduced to a trickle.
I'd definitely recommend a high-clearance truck or SUV for this one -- the road starts out ok, but gets progressively worse as you go. But once you get there, it's a short walk (less than a quater of a mile) from the road. The trail is well established at the road, but pay attention in the middle section as it dog-legs to the left around some fallen trees.
Directions: Take I-26 to the Erwin/Jonesborough exit (#37), turn east towards town and drive 0.4 miles until you reach a stop light. Turn right onto Main Street and drive 0.3 miles to Love Street, turn left. You'll travel through four red lights on Love Street. Continue straight through the fourth stop light, the road becomes Okolona Dr. You'll pass by a school on your right. At the T-intersection, turn left on Martin's Creek Road and continue 1.5 miles (the last 0.9 mile of which is gravel) to an unmarked trail head on your left (there's room for one car to park there). There's another parking area a short distance further up the road. Erwin can be a bit confusing, so I recommend you print out a map before you go -- click here and then look under "road maps".
