There are several things that make this waterfall hike great. To start, during the warmer months, you can often find salamanders along the base of the falls. During the winter, "the waterfall can freeze into a beautiful icy column," the NPS writes. No matter the time of year, though, the mixture of beautiful hemlock and rhododendron tunnels will surely bring a smile to your face.

As for parking, look for a designated hiker parking lot near the Cosby Picnic Area. Alternatively, if you are spending the night within the campground, there is a spur to access Gabes Mountain Trail instead. The trail is well marked, and the simple out-and-back makes it hard to get lost. The waterfall is located about two miles up the trail and accessed by spur trail to its base.
