Walden Wednesdays

From Openwaterpedia

An opportunity for a group of swimmers who enjoy swimming in Walden Pond in Concord, Massachusetts, U.S.A.

Walden Wednesdays are a chance to get out from the city of Boston and enjoy the serenity and beauty of Thoreau's famous Walden Pond. Although spearheaded by members of the Cambridge Masters Swim Club, any and all swimmers are welcome, regardless of affiliation.

The group also makes a special outing to Woods Hole on Cape Cod in Massachusetts at summer's end in order to view the bioluminescent waters and the glowing (but non-stinging) jellyfish. The group also gets together for several post-swim beers and an annual BBQ each year.


Attendees range from die-hard open water swimmers who are looking for a chance to train, to non-competitive swimmers who want to enjoy a cool dip in the idyllic setting.

Swim Schedule[edit]

Every Wednesday, rain or shine, beginning Wednesday, June 15 and lasting through the end of September or whenever the Pond is deemed too cold. If the forecast looks threatening, call the Walden hotline to make sure the park is open before you drive out: +1-978-369-3254.

The group forms carpools out to Walden Pond, departing from various Boston area locations around 5:45 pm and meeting in front of the Walden guardhouse at 6:30 pm. As the daylight begins to wane at the end of the summer, the group often meets earlier to avoid getting locked out of the parking lot when the Pond closes early.

Parking costs US$5 and the lots fill up quickly, especially in good weather. It's highly recommended to purchase an annual pass for US$35 to avoid waiting in line to pay each week.
