Twin Falls
Twin Falls at Rock Island State Park is an unusual roughly 80-foot waterfall that bursts directly from the gorge wall, fed by underground seepage from the Collins River rather than a surface stream. It can be viewed from an overlook or reached along the Downstream Trail.
Before you go
Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check Tennessee State Parks (Rock Island State Park) for closures and current conditions, and confirm land status before setting out.
Frequently Asked Questions
Twin Falls drops about 80 feet. That makes it the 267th-tallest documented waterfall in this inventory, taller than roughly 62% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Downstream Trail reaches it about 1.55 miles (out-and-back), rated moderate. The nearest town is Rock Island. That describes the route as documented, not conditions on the day — check with Tennessee State Parks (Rock Island State Park) for closures and current conditions.
Spring; depends on dam releases and groundwater. Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
