About This Route
The Sinks, located along Little River Road in Great Smoky Mountains National Park, features a dramatic 30-foot waterfall cascading into a churning pool amid mossy boulders and rhododendron thickets. While stunning for viewing from the parking area or nearby trails, scuba diving here draws misguided adventurers due to the deep, clear pools formed by the Little River. According to National Park Service (NPS) records, this spot sees frequent rescue operations; swimming, tubing, and diving are explicitly prohibited and extremely hazardous. Drownings have occurred, with submerged hazards lurking just below the surface. NPS emphasizes that water recreation is not recommended park-wide, as help can take hours to arrive. Visibility may seem good from above, but turbulent flows reduce it underwater to mere feet, making navigation perilous.
Safety Considerations
Scuba diving at The Sinks violates park regulations and endangers lives. River levels rise rapidly from upstream thunderstorms, even on clear days at the site; check USGS gauges for Little River near Townsend before approaching. Strong undertows and hydraulic currents can trap divers against rocks or recirculate them endlessly. NPS reports multiple fatalities from leg entrapments in boulders during swims; scuba gear adds entanglement risks with logs and debris. Never dive solo; use a surface support team with ropes and throw bags. Follow PADI standards for overhead environments, but recognize this is no training site. Hypothermia strikes quickly in 50-60°F waters year-round. Adhere to Leave No Trace by avoiding the area entirely for water entry. Real scenario: In 2022, tubers were swept over falls during a flash flood, highlighting risks for any submersion.
Essential Gear
Beyond standard scuba kit (BCD, regulator, cylinder, mask, fins, wetsuit 5-7mm), carry a drysuit for cold flows, redundant air source, lift bag for entanglement escape, dive light for low viz, and signaling SMB. Include PFD for surface swims, first-aid kit with tourniquet, and satellite communicator like Garmin inReach.
Emergency Tips
If caught in current, float feet-first on back; do not stand. Signal 911 via phone or inReach; rangers patrol Little River Road but response exceeds 1 hour. Evacuate upstream to parking lot for helicopter access. Prevent panic; share dive plan with park rangers at Sugarlands Visitor Center.
