About This Route
Yellowstone Lake, at 7,733 feet elevation and over 130 miles of shoreline, offers stunning kayaking opportunities along its southern and eastern shores. Popular starting points include Bridge Bay Marina or Squirrel Bay, where paddlers can hug the shoreline toward Mary Bay or Stevenson Island. This route emphasizes staying within 300 yards of shore, per National Park Service (NPS) guidelines, to minimize open-water risks. Expect glassy mornings turning choppy by afternoon as winds whip up from the Pelican Valley. Wildlife sightings, like ospreys diving for cutthroat trout, add thrill, but bison on beaches demand caution. Plan 4-8 hour outings, launching after mandatory Aquatic Invasive Species (AIS) inspection at marinas.
Safety Considerations
Cold water temperatures hover in the 40s Fahrenheit even in July, per NPS data, risking hypothermia within 15 minutes of immersion. Sudden afternoon winds generate 3-5 foot waves, as documented in park boating reports. Follow US Coast Guard (USCG) rules: every paddler needs a wearable Type III PFD, like the NRS Chinook, securely fastened. Paddle near shorelines for quick swims to safety, and avoid crossings to Frank Island. Bear country protocols apply; carry bear spray in a quick-draw holster and make noise in fog-shrouded bays. Adhere to Leave No Trace by packing out all waste. Check NPS alerts for algal blooms or high fire danger affecting visibility.

Emergency Tips
p>In a capsize, stay with your kayak as a flotation device; use paddle as a brace to right it. Signal rescuers with three whistle blasts or mirror flashes toward shore. Activate personal locator beacon (PLB) like ACR ResQLink if separated. Prevent hypothermia by changing into dry layers immediately upon landing. Report incidents to Bridge Bay Rangers at 307-344-7311.
