The Groton Parks & Recreation Holiday Lights Ride is already full. It's the free guided bus tour of decorated homes in Groton and Mystic, scheduled for Monday, December 7, from 4:15 to 6:30 p.m., and the registration page showed it as full in mid-October. It was the only event on Groton's early holiday calendar that needed a reserved seat.
Everything else on that calendar runs on a different model. The two biggest Groton nights are listed as free and open to the public, and so are the Mystic events on either side. Between Saturday, November 28 and Tuesday, December 8, the season fits into eleven days, and the Town of Groton and the City of Groton anchor the middle of it with a weekend they built together.
The weekend the Town and the City share
The Town of Groton Parks & Recreation and the City of Groton promote their December events under one name, Groton's Holiday Fest, and call it "a two-day joint holiday weekend." Each night has a different host, a different setting and a different style.
Friday, December 4: the Town's Season of Celebrations
- Time: 6:00 to 8:00 p.m.
- Where: Thrive55+ Senior Center, 102 Newtown Road
- Cost: Free and open to the public
- Format: Mostly indoors, with carriage rides outside the venue
Saturday, December 5: the City's Holiday Lights Parade and Tree Lighting Festival
- Time: 5:00 to 7:30 p.m.
- Where: Broad Street to the City of Groton Municipal Building
- Cost: Free and open to the public
- Format: Outdoors, on the street, with the tree lighting at 7:05 p.m.
So Friday is a venue night and Saturday is a street night. That difference decides who in the house goes to which one, what everyone wears, and where you park the car.
Friday at Thrive55+ is built for staying put
The Town's event used to be called the Holiday Kick-Off. The Town says it changed the name so it would better reflect the range of celebrations the evening includes and help the event stand out. The event page describes it as a one-night celebration of Christmas, Diwali, Hanukkah, Kwanzaa and Three Kings Day.
The two hours are packed, and most of the program stays in one building, so it works well for younger children:
- Santa arrives by fire truck, and photos with Santa are free.
- Gingerbread activities are hosted by the Groton Public Library, with crafts, treats, games and an appearance by the Gingerbread Man.
- Horse-drawn carriage rides run outside the venue.
- Christmas Tree Alley is a row of themed trees decorated by local charitable organizations.
- The Snowflake Drop comes near the end of the evening. Hundreds of paper snowflakes fall from above, and anyone who finds a specially numbered one wins a prize.
- A sensory-friendly chill room offers a quiet, low-sensory space, including its own sensory-friendly visit with Santa.
- Music and food include live music, caroling, hot cocoa and cookies. A food truck sells food on site.
The Snowflake Drop is the reason to stay until close. It happens toward the end, and the prize snowflakes only reward the people still in the room. The sensory-friendly room matters to families who usually skip big holiday crowds. It means the Town's busiest night of the season has a calmer option built in.
This year's Friday also includes a holiday light display from Keeping Spirits Bright. It's a community effort with the Brian Dagle Foundation that lights homes and businesses across southeastern Connecticut in remembrance, connection and hope. People can sign up to decorate their own home or business, put up a yard sign or poster, and follow the trail of lights through the Go Mystic app. The page also invites visitors to walk the lighted trail at the Season of Celebrations. For anyone who already puts up lights every December, signing up adds their house to a regional map.
Saturday in the City happens on the street
The second night runs on the City's streets. At 5:00 p.m., the Holiday Lights Parade steps off from Broad Street at Groton Heights Baptist Church. It goes down Monument Street to Meridian Street and ends at the City of Groton Municipal Building. The event lists decorated floats, city vehicles and walkers, plus light displays, hot cocoa, warm drinks, sweets and live music. The City of Groton's own calendar also lists the December 5 date at 5:00 p.m.
There is a gap in the schedule worth knowing about. The parade starts at 5:00, but the tree lighting at the Municipal Building isn't until 7:05 p.m. If young children can only last one part of the evening, choose between them. If you want both, plan for two hours outside on a December evening.
The route also helps with choosing a spot. The parade ends where the tree is lit, so anyone watching along Meridian Street near the Municipal Building can see the tail end of the parade and then stay put for the lighting.
The next morning, the City calendar lists a "Stuff a Cruiser Event" on Sunday, December 6, from 10:00 a.m. to 1:00 p.m. at 295 Meridian Street. The listing gives the name, time and address but no description, so check with the City before planning around it.
The weekend before: Mystic on the water
The Groton weekend falls in the middle of the eleven days. The first weekend of the stretch is on the Mystic River.
On Saturday, November 28, the Mystic Holiday Lighted Boat Parade sends decorated boats down the Mystic River just after 6:00 p.m. It is free, and CTvisit's listing points readers to the Mystic Chamber for details. Earlier that day, the Greater Mystic Chamber's calendar lists an Artisan Market on Cottrell Street near Mystic River Park, running from 11:00 a.m. to 7:00 p.m. That puts the market and the parade on the same afternoon in the same part of downtown. You can browse the makers' stalls before dark and stay for the boats.
A side note for boat owners: the Chamber's event calendar carries a boat registration listing for the lighted parade, aimed at people who haven't hauled out yet for the season. The registration blurb still mentions a Saturday, November 29 date, but the calendar entry and CTvisit both list Saturday, November 28 for 2026.
On Sunday, November 29, the Holiday Magic Market at the Haley Mansion, 9 Williams Avenue in Mystic, runs from 10:00 a.m. to 3:00 p.m. The Chamber listing says this is the market's third year and promises local makers and holiday shopping.
The weekday that closes it out
The stretch ends on a Tuesday. The Downtown Mystic Holiday Stroll is on Tuesday, December 8, from 5:00 to 9:00 p.m. The Chamber lists carolers, Santa and shops staying open late, and the event is free. It's the longest evening window on the calendar at four hours, and it runs on a school night, so it suits a stop after work more than a full family evening.
The full-up Holiday Lights Ride sits the night before, on Monday, December 7. If you missed it this year, the takeaway for next year is simple. Groton Parks & Recreation opened registration early enough that every seat was gone by mid-October.

If you're hosting family in Groton over the holidays, or showing someone around who's thinking about making this stretch of the shoreline home, I'm always glad to share which Friday-night and Saturday-street traditions are worth building a visit around.
