4 Days in Boston, United States: From Faneuil Hall to North End Food

US citizens do not require a visa. Citizens of most EU countries, the UK, Australia, and New Zealand typically qualify for the ESTA visa waiver program for stays up to 90 days. Indian citizens require a B-1/B-2 visitor visa. All travelers must possess a passport valid for at least six months beyond their intended period of stay, and other nationalities should check the U.S. Department of State website.

Boston has a very low crime rate for a major US city, making it generally safe for tourists, even solo female travelers. The main specific cautions are being aware of uneven historic sidewalks to prevent falls and heeding warnings in potentially unsafe structures on the Boston Harbor Islands. In emergencies, dial 911.

Boston is highly walkable, especially downtown and along the Freedom Trail. For longer distances, use the MBTA subway ('T') and bus system with a CharlieCard or CharlieTicket. Ride-sharing services like Uber and Lyft are also widely available. Traffic can be heavy, so public transit is often the most efficient option within the city.

The most cost-effective way is the MBTA Silver Line bus (SL1), which departs from all terminals and goes directly to South Station, offering free transfers to the Red Line subway. Alternatively, water taxis offer scenic routes to various waterfront locations, or you can take a taxi/rideshare for direct but more expensive service.

The currency is the United States Dollar (USD). Credit cards are widely accepted at nearly all establishments, making them the primary method of payment for most travelers. Carrying some cash (USD) is useful for small purchases, street vendors, or smaller, cash-only businesses. ATMs are ubiquitous throughout the city.

Tipping is customary and expected for most service industries in Boston. A general guideline for restaurants is 15-20% of the bill for good service, with 18% being a common baseline. For taxi drivers, 15-20% is typical. Hotel bellhops usually receive $1-2 per bag, and housekeepers $2-5 per night.

Pack layered clothing due to Boston's famously changeable New England weather, and be sure to include water-resistant walking shoes for potentially wet and uneven cobblestone streets and sidewalks. A compact umbrella is useful for sudden showers. During colder months (October-April), include warm hats and gloves. Remember to bring a reusable shopping bag, as Massachusetts has a statewide plastic bag ban.

The best times to visit Boston are late spring (May-June) or early fall (September-October). These periods offer pleasant temperatures (10-22°C), blooming flowers or vibrant fall foliage, and comfortable conditions for walking and sightseeing. While summer (July-August) is popular, it can be hot and humid, with larger crowds and higher prices.
