- 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.
Brookhaven is a town of about 486,000 people covering most of central Suffolk County, from dense suburbs near Route 112 out to pine barrens and the Atlantic shore. It is not one place: Port Jefferson and Stony Brook are the walkable, stay-here parts, while Smith Point, Wertheim and the Rocky Point preserve need a car. Two nights is enough for a beach-and-village trip; one night if you are only passing between New York City and the North Fork.

Arrive & move
Airports are listed under At a glance; this is how to move once you are in
Getting around
A car is the practical way to cover the town: the Long Island Expressway, Sunrise Highway, Nicolls Road and William Floyd Parkway link the villages, beaches and preserves. The LIRR serves Ronkonkoma (Ronkonkoma Branch) and Port Jefferson (Port Jefferson Branch) from New York City; buses and taxis fill gaps but are slow. Parking at Smith Point fills by mid-morning on summer weekends.

- Summer weekend traffic on Sunrise Highway and Route 25A backs up; go early.
- Some south-shore blocks in Mastic, Mastic Beach and North Bellport see elevated crime; most visits never touch them.
- Many seasonal places (ice-cream stands, beach concessions) close outside warm months — check before you drive.
- Brookhaven National Laboratory is normally closed to the public; open houses and group tours need advance booking.
