A car is highly recommended for exploring beyond major cities, especially the Eastern Shore and Western Maryland. Major rental agencies are available at airports (BWI, DCA, IAD) and cities. Baltimore has a light rail, subway, and bus system (MTA). The Washington D.C. Metro system extends into Maryland's D.C. suburbs. Ride-sharing apps (Uber, Lyft) and taxis are widely available in urban areas. Annapolis and Baltimore's waterfront areas are very walkable. For regional travel, MARC commuter trains and Amtrak connect Baltimore, D.C., and other East Coast cities.
Late spring (May-June) and early fall (September-October) offer the most pleasant weather—mild temperatures, lower humidity, and beautiful foliage in the fall. Summer (July-August) is peak season for beach destinations like Ocean City but can be hot and humid, especially in urban areas. It's ideal for Chesapeake Bay activities and festivals. Winter (December-February) is colder, with potential for snow in western regions, but offers holiday events and fewer crowds.
Maryland has a relaxed, friendly atmosphere. Casual dress is acceptable in most places, though upscale restaurants in cities may require smart casual attire. Tipping is standard: 15-20% in restaurants, $1-2 per drink at bars, and a few dollars for hotel housekeeping and taxi/ride-share drivers. Be prepared for passionate discussions about the best way to eat crabs (typically messy, with mallets and Old Bay seasoning) and local sports teams (Ravens, Orioles). Politeness is valued.
Maryland is generally safe for tourists. Exercise standard precautions in urban areas: be aware of your surroundings, especially at night, and secure valuables. Some neighborhoods in Baltimore have higher crime rates; research areas and stick to well-trafficked tourist zones like the Inner Harbor, Fells Point, and Federal Hill. Driving safety is important; obey traffic laws. Be cautious of common tourist scams like overpriced tours or street games. Weather-related safety is key—heed warnings for thunderstorms, hurricanes (rarely on the coast), and winter snowstorms.
No special vaccinations are required for travel to Maryland. Standard travel health insurance is strongly recommended as U.S. medical costs are high. Excellent hospitals are available in major urban areas like Baltimore (Johns Hopkins Hospital, University of Maryland Medical Center) and Bethesda (Walter Reed National Military Medical Center). Common health concerns include seasonal allergies (spring/fall) and tick-borne illnesses like Lyme disease in wooded areas; use insect repellent. Tap water is safe to drink. For emergencies, dial 911.
