Prince Frederick
Give Prince Frederick one night, or use it as a lunch-and-swamp stop on the drive between Washington and Solomons: two sights, no town centre to wander.
Prince Frederick is a small Calvert County crossroads on MD-4, about an hour's drive south of Washington, DC. There is no rail and no walkable downtown of sights: you come by car for a cypress swamp boardwalk, a riverfront history park and crab cakes, then move on to Solomons or Point Lookout. Two nights is the ceiling unless you are visiting family.

- 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.

Getting around
You need a car. MD-4 runs north–south through town and MD-2 branches north toward Annapolis; there is no useful local bus for visitors and no rail. A Maryland Transit Administration commuter bus connects the area with Washington, DC on weekdays — check current routes and times before relying on it. Distances between the swamp, the park and the restaurants are 10–25 min by car.
