Chasteen Creek is an easy hike in the Smoky Mountains National Park. The easiest approach is from the Smokemont campground. Drive all the way through the campground to the very back where there is parking for about 10-12 cars in front of a gated road. This is the Bradley Fork Trail which follows Bradley Fork upstream. Chasteen Creek Trail is the first right, about 1.2 miles (2 km) in. Just after the turn is backcountry campsite 50 which has good creek access. A half mile or so (~ 1km) up this trail are the cascades.
It’s a relatively small set of falls but there is a nice viewing area which would make a good picnic spot on a longer hike (like the Smokemont Loop).
Campsite 50 is also one of the easiest backcountry sites to reach in the park. Just over a mile each way and relatively flat. There are three fire pits set up there.
