Run, walk, or dance into the chilly waters of Big Bear Lake on Saturday, March 3rd to raise funds for Special Olympics Inland Empire. For just a minimum of $50. The Polar Plunge is an event where all participants race into the frigid waters of Big Bear Lake. Plungers decide how deep they’ll go and how long they stay in the water. Some Plungers only get their ankles wet while others stay in until the lifeguards make them leave the water! The goal of the 7th Big Bear Polar Plunge is to raise a minimum of $100,000.
