Hammonasset Beach State Park at 1288 Boston Post Road never shuts down. It's open daily from 8 a.m. to sunset, all year. The summer season doesn't end on one day, though. It ends in steps, and each step gives back a part of the park that summer rules keep closed. The first step came on September 30. The last scheduled one on this fall's calendar is November 14.
As of today, October 7, 2026, one of those steps has happened and three are still coming. Here's the order.
- September 30. Dogs can go back on the beach.
- Monday, October 12, at noon. The campground closes and starts its pet season.
- Saturday, October 31. Nonresident parking fees end for 2026.
- Late October into mid-November. Meigs Point Nature Center fills the quieter park with evening and weekend programs.
The Beach Belongs to Dogs Again, With a Seven-Foot Limit
The state's Hammonasset page sets the beach pet season at September 30 to April 1. Leashed pets are allowed in the picnic areas all year. The Friends of Hammonasset pet policy gives slightly different dates, October 1 to March 30. That page was posted in 2020, and its dates are one day off at each end. The state's park page is the current, official listing.
The Friends page also sets a rule the state page doesn't. Dogs have to be leashed in the picnic and other areas, on a leash no longer than 7 feet. It also asks visitors to follow wildlife-nesting signs where they're posted. Statewide park policy keeps pets out of buildings, swimming areas and campgrounds unless a park sets its own rule. That exception is where Hammonasset's second handoff comes in.
The park's coastal walk runs 3.4 miles and includes boardwalk. Trails go out to Meigs Point and Willard's Island. Neither trail has a named dog ban in the park's public information, so posted signs decide. The state's summer warning that paved trails get "sizzling hot" on bare feet and paws matters less once October cools the asphalt.
October 12: The Campground Empties and Opens to Pets the Same Day
Hammonasset's campground has 558 grassy sites, eight of them rustic cabins, in loops a short walk from the beach. The 2026 season opened Friday, May 22, and closes Monday, October 12, at noon. October 12 is also Columbus Day. During the camping season, the "Know Before You Go" list says no pets are allowed. The park's pet chart lists the campground as open to pets from Columbus Day to May 1.
So on the afternoon the last campers leave, those loops join the beach and picnic areas as places a leashed dog can go. They'll stay that way until spring. The same date ends the park's summer 24-hour access, which covers camping and fishing from Memorial Day to Columbus Day. After that, the park keeps regular hours.
The dates repeat closely next year. The state has already posted the 2027 campground season as Friday, May 28, through Monday, October 11, at noon.
October 31: The Last Day the Lot Charges Anyone
Cars with Connecticut plates already get in free. Out-of-state cars pay $15 on weekdays and $22 on weekends and holidays. The DEEP parking and camping fee page says those charges run from April 1 through October 31. The state's reservation system lists the Hammonasset day pass as open through Saturday, October 31, 2026. Visitors still have to pay when the ticket booths are closed.
This step matters most to anyone hosting family from New York or Rhode Island this fall. A guest who visits the weekend before Halloween still pays the weekend rate. A guest who visits in November parks free, the same as a Madison car. The off-season gate schedule is simple. Gates unlock at 8 a.m. and lock at sunset. Sunset comes earlier each week, so the park's day keeps getting shorter even though the posted hours stay the same.
What Fills the Quieter Park
With the campground empty and the fee booths done, the busiest building at Hammonasset is Meigs Point Nature Center. Its fall 2026 calendar runs past every rule change above.
Saturday, October 24: Bats in Connecticut. Two sessions, at 11 a.m. and 1 p.m.
Friday, October 30: Owl-O-Ween. This is the one with the most going on. The evening is split into two sessions, 6 to 7 p.m. and 7 to 8 p.m. No registration is needed, and the suggested donation is $5 per person. It features live owls, opossums and snakes, plus crafts, face painting, henna and glitter tattoos. Costumes are welcome. The event page describes the two sessions this way:
Early Bird Visit from 6–7pm or Night Owl Visit from 7–8pm (Less Crowded)
Owl-O-Ween supports Connecticut wildlife rehabilitators. It's hosted by Meigs Point Nature Center with A Place Called Hope, Freedom First Wildlife Rehab and Farm River Wildlife. It's the night before nonresident fees end, so it's the last event of the season held under summer parking rules.
Friday, November 6: Astronomy Night. From 7 to 9 p.m., with Saturday, November 7, as the rain or cloud date. Early November sunsets help a night-sky program on an open stretch of coast.
Saturday, November 14: Hammonasset Fall Festival. From 11 a.m. to 4 p.m., with seasonal activities, treats and educational exhibits.
The center's own hours need a call before a weekday visit. Friends of Hammonasset lists Tuesday through Sunday, 10 a.m. to 5 p.m., from April through October. From November through March it lists 10 a.m. to 4 p.m. The Meigs Point Nature Center homepage shows Tuesday through Sunday, 10 a.m. to 5 p.m., with no separate winter schedule. Neither page dates its hours. The center's number is 203-245-8743.
The Route 1 Edge of the Park
The stretch of Boston Post Road outside the park gate has its own seasonal clock. The biggest local story there this year came from across the road.
Donahue's Clam Castle is back with the Donahue family. Patch reported in February 2026 that the popular seafood spot planned to return in spring after its stretch as Taco Pacifico. The Connecticut Scoop posted it as open on April 19, 2026. The Scoop gives the address as 1325 Boston Post Road. The restaurant's own Visit Us page lists 1324 and posts these hours: Monday to Thursday 11 a.m. to 7:30 p.m., Friday 11 a.m. to 8 p.m., Saturday 11:30 a.m. to 8 p.m., and Sunday 11:30 a.m. to 7:30 p.m. Its homepage calls the business seasonal, running from spring until "the end of summer." It hasn't posted a 2026 closing date, so check the site before an October lunch.
Nearby, Lenny & Joe's in Madison lists restaurant hours of 11 a.m. to 8:30 p.m. Sunday through Thursday and 11 a.m. to 9 p.m. Friday and Saturday. Its outdoor ice cream shack is listed as open daily from noon to 7:30 p.m., weather permitting. In October, the weather decides more of those days than the schedule does.
What's Planned, Not Yet Built
The off-season is also when work gets planned for the seasons ahead. DEEP's Restore CT State Parks list includes four Hammonasset items:
- East Beach bathhouse deck replacement, estimated at $110,000
- Repaving of the main park entry road, at $1.5 million
- Main gate and ticket booth roof replacement, at $30,000
- Design work for a public-access pier at Meigs Point, at $250,000
None is marked complete, and the list gives no construction dates. The pier is listed as design work only. There's no boardwalk replacement on the list. Separately, Audubon Connecticut announced on June 4, 2026, that it has funding to begin planning and design of a living shoreline for a salt-marsh restoration at the park. The announcement describes the first step as planning and design, and it doesn't give a construction date.
By November 14, every fall step will be done. Leashed dogs will have the beach, the campground loops and the picnic areas. Every car will park free. The gates will open at 8 a.m. and lock at sunset until the campground reopens in late May 2027.
Fall changes how a Madison home lives too. A house near the park gate gets a different kind of quiet once the camping and fee season ends.
