About This Route
Sedge Bay Cove on Yellowstone Lake offers one of the calmer spots for stand-up paddleboarding in Yellowstone National Park. Nestled between the main lake and protected shorelines, this area features shallow bays with grassy edges and minimal currents, ideal for beginners practicing balance. Launch from the gravel beach near Sedge Bay trailhead, accessible via the main park road from Lake Village. Paddle along the 1-2 mile shoreline loop, spotting birds and occasional bison from afar. Water depths stay under 10 feet near shore, reducing open-water exposure. According to NPS boating guidelines, SUPs are permitted here after mandatory Aquatic Invasive Species (AIS) inspection at Bridge Bay or Lake ranger stations.
Safety Considerations
Yellowstone Lake water remains frigid, often 45-55 degrees Fahrenheit even in peak summer, risking hypothermia within 15 minutes of immersion per REI cold water safety protocols. Sudden afternoon winds from the west can whip up 2-4 foot waves in adjacent open water; stick to coves and monitor weather via NPS apps. Wildlife hazards include moose in shallows and bison on beaches; maintain 25-yard distance as per NPS rules. Complete AIS inspection: clean, drain, dry your board 30 days prior if trailered, or pass same-day check. Wear a USCG-approved Type III PFD at all times; SUP leashes are essential to avoid board drift in wind. Launch only during boating season, Memorial Day to October 31. Check current conditions at nps.gov/yell for wind advisories and lake levels.
Essential Gear
Pack a stable inflatable SUP like the Red Paddle Co 10'6" for beginners, paired with an adjustable paddle from Werner. Neoprene wetsuit (3/2mm), booties, and gloves combat cold; add a dry bag for phone and snacks. Whistle and signaling mirror for emergencies. Follow Leave No Trace: remove all gear traces to prevent AIS spread.
Emergency Tips
If you capsize, climb onto your board immediately to conserve heat; use paddle as signal. Activate personal locator beacon if equipped, or whistle in threes. Stay near shore; help may take 1-2 hours from Lake ranger station. Prevent group separation by buddy system.
