Groton, Connecticut
Groton
Give Groton one full day for the Submarine Force Museum and Fort Griswold, then sleep in Mystic: the sights are 10–15 min apart by car.
Groton is a small coastal city on the Thames River, split between a working naval town and the tourist village of Mystic in its eastern half. Almost everything a visitor wants sits on two roads: Crystal Lake Road for the submarine museum and Fort Griswold, and Route 27 for Mystic. One night is enough unless you are using it as a base for the whole Mystic–New London coast.

Get around
A car is the practical choice: the museum, the fort and Mystic are 10–15 min apart and buses are thin. Amtrak serves New London across the river, about 10 min by car or taxi from Groton centre. I-95 exits 85–87 and US Route 1 link the pieces.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake and 'hi, how are you?' — reply 'good, thanks'; avoid: Treating the question as a real health enquiry
- Restaurants: Tip 18–22% and wait for the check; avoid: Leaving without tipping
- Personal space: Keep an arm's length in queues; avoid: Standing close to strangers
- Politics and religion: Listen more than you speak; avoid: Opening with hot-button topics
- Smoking: Smoke only in marked areas; avoid: Smoking near doors or in parks where banned
Scams and watch-outs
- The Submarine Force Museum runs winter hours (closed some days): check before you drive out.
- Fort Griswold is an outdoor hilltop site with uneven ground and no shelter.
- The naval base is an active military installation: no public access without prior arrangement.
- Summer weekends fill Mystic hotels and Route 27 traffic; book ahead.
Groton is a normal small New England city: the real risks are I-95 traffic, dark unlit roads around the fort at night, and summer rip currents at nearby beaches. Lock the car and keep to lit streets after dark.
