About This Route
Lewis Lake's southern shorelines south of the Lewis River outlet offer advanced stand-up paddleboarders a 3-5 mile coastal paddle with volcanic beaches and mountain views. Launch from the South Entrance road pullout or Lewis Lake Campground beach; follow the shoreline northwest toward Shoshone Creek inlet. Windswept but sheltered sections allow skill-building; NPS allows non-motorized craft here after AIS check, though open lake crossings are discouraged due to wave risks.
Safety Considerations
Lake temperatures hover at 45-60 degrees Fahrenheit; NPS reports frequent wind shifts creating 4-6 foot swells, stranding paddlers. Paddle hugging shorelines only; avoid mid-lake per park advisories. Grizzly bear habitat demands bear spray on board; noise to deter approaches. AIS inspections at South Entrance station are rigorous; dry boards 18-30 days if suspect. Leash and PFD mandatory; test gear in shallows. Monitor for rising barometric pressure drops signaling storms via park weather stations.
Essential Gear
12'6" race SUP like SIC Maui for stability in chop; ergonomic paddle. Full drysuit ensemble with booties, hood. Bear spray holster, EPIRB, and thermal blanket. REI recommends redundant signaling devices.
Emergency Tips
Capsize protocol: board as flotation, bear spray ready. Paddle to nearest campground beach; signal aircraft with paddle crosses. Solitary paddlers: activate EPIRB immediately.
