Cohasset
Go for one day, not a base: harbour, Maritime Museum and a Greenbush Line ride from Boston, 45–60 min each way.
Cohasset is a small South Shore town of about 7,500 people on a sheltered harbour, 30 km southeast of Boston. It is a half-day or one-night stop, not a destination in itself: a maritime museum, a seasonal music tent, a harbour walk and a handful of restaurants. Most visitors come by MBTA Greenbush Line or by car on Route 3A.

- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.
