The 3-day plan, rearranged for 6 days: every place stays and a few more are added, and each day keeps to one part of town.
From average weather, 2021 to 2025: days that are warm but not hot, with few rainy days, score highest. Crowds and prices change through the year, so check them before you book.
How much walking? On foot, about 0.2 to 1.0 miles a day, and 64.5 miles by car or transit in all across 6 days. Distances are straight-line estimates, so allow extra for the streets.
Built from the plan’s must-sees, grouped so each day stays close together and ordered by time of day.
A museum of Native American culture in Mashantucket, owned and run by the Mashantucket Pequot Tribal Nation. A drive north of Mystic, and a museum, not the casino beside it.
Go when Midday, as an indoor stop.
Local tip A museum of Native American culture, owned and run by the Mashantucket Pequot Tribal Nation. It is a museum, not the casino, and it deserves a quiet, unhurried visit. Check ahead on the opening.
A small harbor town on a point of land that reaches into Little Narragansett Bay, with two main streets, old colonial, Federal and Greek Revival houses, and a working fishing and lobster fleet. Walk the streets, look at the boats and keep your pace slow.
Go when Afternoon, then a slow walk to the point (about 6:57 PM).
Local tip It is a small place for walking rather than a long list of sights. Look at the old houses on the two main streets, then watch the fishing boats. Check ahead on parking, and walk once you park.
A stone lighthouse built in 1840 on the east side of the harbor in the borough. It went out of service in 1889 and has been a museum since 1925. Look at the tower from the street, and check ahead on whether the museum is open.
Go when Late afternoon (about 6:57 PM), when the light softens on the stone.
Local tip The tower is small and stone, with a view across the harbor. Look at it from the street first, and check ahead on whether the museum is open and whether children can go up.
The creamy New England kind, thick with potato and chopped clams and eaten with small round crackers. Rhode Island, just next door, also makes a clear version, so ask which one is on the menu.

Built from the plan’s must-sees, grouped so each day stays close together and ordered by time of day.
A maritime museum on the river with a collection of ships and boats and a re-created 19th century seaport village of more than 60 historic buildings. The whaling ship Charles W. Morgan, built in 1841, is part of the collection. Plan on most of the morning, wear shoes for old wooden decks, and check ahead on which ships, workshops and demonstrations are open.
Go when Morning, as a full outing with a lunch break.
Local tip Pick two or three things rather than all of it, such as a ship, a workshop and the waterfront. Wear shoes for wooden decks, take a jacket for the wind off the water, and check ahead on what is open.
A marine aquarium in Mystic. Its Wikipedia article lists Steller sea lions, belugas, a ray and shark touch pool, African penguins and a jelly gallery. Check ahead on timed entry, on which exhibits and shows are open, and arrive early with children.
Go when Morning, as soon as you can get in.
Local tip Go to the animals first and the shops last. Children often want the touch pool and the sea lions again, so keep a little time at the end. Check ahead on timed entry and on which shows are on.
Lobster meat warmed in melted butter and piled into a toasted split roll, the Connecticut way. Some places also serve it cold with mayonnaise, so ask which you are getting.
Local tip Ask for a side of chips, and wipe your hands well before you touch the ropes on the ships.
A bascule bridge over the Mystic River that carries cars and people on foot into the middle of the village. A bascule bridge lifts to let boats through, so stop and look if you see it rise. Children tend to like this stop, and a few minutes is enough.
Go when Morning, before the village fills.
Local tip Stand on the sidewalk and look down the river. If the bridge starts to rise, stay back from the edge and let children watch the boats pass through. Hold small hands near the road.
Built from the plan’s must-sees, grouped so each day stays close together and ordered by time of day.

A museum on the Thames River in Groton run by the Navy. It holds USS Nautilus, the first nuclear powered submarine, and visitors can take a self-guided audio tour of the boat. Passages are narrow, so mind your head and the steps, and check ahead on the opening and any rules on entering the base area.
Go when Afternoon, as an indoor stop.
Local tip The boat is the draw, with narrow passages, low doors and steep steps, which suit older children better than toddlers. Check ahead on the opening and any entry rules.

It is the site of the Battle of Groton Heights on 6 September 1781, where a small Connecticut militia force met a larger British force, and many defenders died. A monument built in the 1820s stands in the park. Treat it as a memorial, and talk to older children about what happened here.
Go when Midday, with the whole family.
Local tip Walk the grounds and read the markers, then look at the monument. It marks a battle where many men died, so keep voices low and talk with older children about it. Wear shoes for grass and slopes.

Go when Morning, before the lot fills.
Local tip Walk the grounds first for the river views, then decide about a tour of the house. There are steps and uneven paths, so check ahead on the opening and the trails.
A seasonal crossing of the Connecticut River between Hadlyme and Chester, the second oldest continuously operating ferry crossing in the state and a state designated historical landmark. It runs near Gillette Castle. Check ahead on whether it is running, and if it is not, plan to cross by road.
Go when Midday, as part of the drive.
Local tip It is a seasonal river crossing, so check ahead on whether it is running before you plan the day around it. If it is not, cross by road and carry on to the museum.
