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!

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 9:30 am. 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.

        After the steamer it ain’t bad at all.
        Try jumping in when it’s 15 degrees and then you may be considered.
        Show up anyhow, you’ll meet some great people from Southie.

    Way before the LGBTQ + Movement there were scores of men unashamed of their naked manliness manifested by jumping into frigid waters at the L Street Bathouse. Southie had the L street bath house way before they became popular in San Francisco. This progressive community celebrated Polar Bears & Cubs way before societal norms accepted them. Congrats to mayor Wu
    For her open support of this colorful event.

    Why is the newly renovated L Street Bathhouse closed on New Year’s Day for the Historic L Street Brownie plunge?
