Ages 3 & Up. Ring in the new year by challenging yourself with a chilly dip into Lake Washington! How will you ring in the new year? Are you a toe-dipper, full on dunker or a run and jumper? We recommend those taking the Polar Bear Dip to bring a towel and dry clothes. US Coast Guard approved flotation devices are permitted for those with limited water/swimming experience. All participants must register to participate. Chowder, coffee, and cocoa will also be available at both Henry Moses Aquatic Center at 12Noon and at Coulon Beach Park at 10am.
