Make a splash at the Polar Plunge at Lake Sammamish State Park!
Join Friends of Lake Sammamish State Park, Washington State Parks and more partners as we splash into the new year. Polar Plunge returns on New Year’s Day 2024. Festivities will begin at 10:30 a.m. with registration, First Day hikes led by Park Staff, music, and merriment on the shores of Sunset Beach. The crowd will “plunge” at noon.
