Little Bradley is a great stop if you're driving up from South Carolina or if you're looking for a great day trip from the Asheville area. The trail is relatively easy and short. I do recommend wearing shoes that can get wet as you will have to do a few stream crossings that vary in depth depending on the time of the year.
I did this in January and it was more than doable. I would recommend visiting during the spring as the water flow is great or in the summer when you can take a dip in the water.
Be mindful of following the right trail - they've put a log on the trail to prevent people from going the wrong way near the first stream crossing. The trail will feel natural to keep going and veer left, but you will actually want to turn right and go across the stream.
There isn't a ton of parking here - maybe room for 8 cars or so, but I've never had an issue. You can also park on the other side near Big Bradley and cross the road.
