An 80-foot segmented waterfall created by seepage from the Collins River through limestone caverns after the Great Falls Dam raised the water table; it emerges from the gorge wall above the Caney Fork at Rock Island State Park. Viewable from a roadside overlook or reached via 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 for closures and current conditions, and confirm land status before setting out.

Frequently Asked Questions

Twin Falls (Rock Island) drops about 80 feet. That makes it the 264th-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 easy. The nearest town is Rock Island. That describes the route as documented, not conditions on the day — check with Tennessee State Parks for closures and current conditions.

Spring (dam-influenced flow). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
