Polar Plunge 2021

January 1, 2021 @ 10:30 am - 1:00 pm


The Lake Sammamish Polar Plunge is back!

This year we will take the New Year’s Day plunge into the lake in small groups of five to adhere to COVID safety protocols. If you are more comfortable plunging on your own, that’s fine too. Plunge from anywhere (pool, hot tub, bathtub, hose over your head) and send us a picture.

Thanks to our sponsor Aegis of Issaquah, the first 200 registrants will receive a souvenir Polar Plunge neck gaiter that doubles as a protective mask! As an extra bonus, plungers will get a coupon for a free cup of clam chowder from Ivar’s. The gaiter and coupon will be mailed to those who plunge by photo.

Registrations will be taken online only. There will be no day-of sign-ups and we cannot guarantee your time slot without pre-registration. Please note that mask-wearing and social distancing will be enforced. Participants and spectators cannot congregate in groups larger than five.


FLSSP reserves the right to cancel the group plunge at the park if Washington State Parks or King County Health officials change COVID protocols.

Please note that the entry fee of $10 is a donation to Friends of Lake Sammamish State Park. Friends of Lake Sammamish State Park is a 501 c(3) dedicated to supporting, promoting, and enhancing the park for the benefit of the entire community.

A $10 Discover Pass is normally required to enter the park but January 1, 2020 is a free day so no pass is required.
