Deep in the heart of the Cumberland Plateau, Tennessee’s Rock Island State Park sits at the confluence of the Caney Fork, Collins, and Rocky Rivers. Here, the Caney Fork River carves through ancient gorges, spilling over jagged ledges to create a landscape defined by the roar of waterfalls. Unlike many parks with a single drop, Rock Island features numerous springs that pour directly out of the rock walls. Great Falls and Twin Falls were my favorites.
Twin Falls
Twin Falls is an 80-foot “accidental” waterfall created when the Collins River began leaking through a porous limestone ridge after the Great Falls Dam was built. Two large cascades pour out of the gorge wall giving the waterfall its twin name. There are several smaller streams that seep out of the wall as well.
Twin Falls Overlook
An upper overlook sits at the end of Powerhouse Road. From there, we had a bird’s-eye view of the waterfall and river. I also spotted a great blue heron wandering the rocky shore.
Downstream Trail
This 1.7-mile moderate trail starts at the overlook parking lot and, as the name suggests, meanders downstream along the river to the base of the falls. From the overlook, stone stairs head down to the dirt trail at water level.
There are a few openings along the trail for visitors to get closer to the river. Here we bounced along the rocks to get closer views of Twin Falls.
Note: Water levels are highly variable in the gorge due to releases from Great Falls Dam. The entire gorge can quickly become flooded making conditions extremely hazardous.
Great Falls
Great Falls is a 30-foot horseshow-shaped waterfall in the Caney Fork River Gorge area. The best view is from an overlook near the historic cotton mill.
Great Falls cascades over ledges on a large outcropping.
Cotton Mill
Built in 1892, Falls City Cotton Mill was the only textile mill in the county before 1930. It manufactured cotton and wool products.
The mill is situated on the bluff above Great Falls on the Caney Fork River. A flume diverted water from the waterfall to the turbine.
The mill operated until the great flood of 1902. While the structure survived and can still be seen today, it was forced to close because its turbine washed away.
Spring Castle
Across the road from the textile mill, Spring Castle is an elaborate spring house. Its reservoir contains water from a natural spring. This water was used by the mill and surrounding houses. It also acted as fire protection for the machine shop connected to the mill. Fires at mills were quite common with hot machinery near flammable materials.
During our visit, large trees had come down next to the spring house, thankfully missing the main structure. They did, however, obstruct the stairs.
Other Park Activities
Nine hiking trails allow visitors to explore the park.
Cold Hole and Warm Hole swimming areas can be accessed in the Caney Fork River Gorge.
For those willing to tackle a strenuous hike, Blue Hole is a popular fishing area.
Launch ramps on the lake, Caney Fork, and Collins River provide access to recreational boating. Rock Island is known for its whitewater kayaking.

Rock Island State Park is a place where Tennessee’s industrial history and the uncontrolled force of the Caney Fork River have struck a beautiful bargain. Pack your boots and lose yourself for a while in the spray of the falls.
Just stunning! Your writings show just how much this country has to offer. Thank you
