Jump in!

We can’t think of a more shocking way to start off the new year by jumping into the frigid waters of Boston Harbor – talk about a jolt! Many believe it is good for one’s health, where one’s immune system can benefit from regular cold water plunges. This belief is part of the foundation of the L Street Brownies – the oldest “polar bear” club in America, and for over 100 years, the polar plunge has been part of the neighborhood culture!

This year the L Street Bathhouse (now the BCYF Curley Community Recreation Center) is currently under major renovations, so the building and the beach behind it are closed.  But the New Year’s Day Polar Plunge will still go on – at M Street Beach!

March from L Street Tavern

L Street Tavern hosts a special march from the bar located at L + 8th to the beach led by the Greater Boston Firefighters Pipes + Drums!  Doors open at 8 am. March to M Street Beach as a group at 8:15am. A special commemorative t-shirt will be on sale for $25.

Be a part of this tradition

The L Street Brownies promote health, fun, and friendship. Each year, the swim is dedicated to past and recently deceased Brownies. Spectators are welcome and creative costumes are encouraged.
