For those who want to avoid a hotel stay, the Boston Christopher may have the solution. They offer studio and one-bed furnished apartments with fully equipped kitchens to let you please yourself. The area has more than 30 parks, lots of varied nightlife and Boston's Back Bay is close at hand.

    Boston beaches in August

    South Boston

    There are four great South Boston beaches to choose from and although they have different names, they run into each other to form a three-mile stretch of golden sands. The beaches have amazing views across Dorchester Bay to the Boston Harbour Islands. Pleasure Bay Beach, The L Street Beach, M Street Beach and Carson Beach have plenty of room to stretch out on the sand, even on busy days, a range of amenities for children and a popular bathhouse at L Street Beach.

    Bars and Restaurants

    Parlor Sports

    No USA visit is complete without a visit to a proper sports bar and Parlor Sports is just that. Whether it's gridiron, baseball, basketball or racing it will be on this relaxed and friendly bar's big screens and the added bonus is an excellent food menu offering everything from light bites to steaks and fish tacos. It also serves specialist local beers and some of Boston's best cocktails.


    Boston is renowned for its high quality and plentiful Italian restaurants and the biggest concentration of them is in the city's Italian quarter, the North End. There are so many to choose from that standards are incredibly high, but for a different experience, try Bricco. This is no pizza joint. Instead, there's rack of lamb, chicken in a brick, various veal dishes and wild boar. Lots of pasta dishes too.

    Deep Ellum

    The lively Allston district in Cambridge is home to Deep Ellum, a bar with a menu that's a cut above the rest. With a loyal regular clientele, this is away from the tourist crowd. Choose from pork belly, charcuterie, pickle plates and other dishes and pair them with your choice of specialist beers from the USA and Europe and unusual cocktails, including the "Mexican Happy Meal" which comprises a tequila, a tecate, and a shot of sangrita.

    Area 4

    Area Four is a collective of restaurants and a café with a shared philosophy of local ingredients and good, simple food. Specialising in pizzas, pasta and oven cooked chicken you can be sure the meat, poultry, seafood and vegetables have a short journey to your plate. Take your pick of venues in Boston and Cambridge that all have their own identity but the same cooking and preparation principles. Highly rated by the locals and the cocktails are excellent too.

    Things to do in Boston in August

    Italian feasts

    This is the month of the Italian feast and has been for more than a century, with four of the most famous taking place in Boston's North End. They celebrate a chosen saint with ceremonies, processions, music and lashings of food and drink and all are welcome.

    They include St. Agrippina di Mineo Feast and Procession starting at Hanover and Battery Streets; Madonna Della Cava Feast in Battery and Hanover Streets; The Fisherman's Feast of the Madonna del Soccorso di Sciacca; St. Lucy's Feast and the largest of them all, St. Anthony's Feast. This is New England's biggest with parades, strolling singers, and hundreds of pushcarts offering Italian food. All are free.

    Visit Cape Cod

    August is the perfect month to visit Cape Cod and its islands. It is 60 miles south east of Boston but the trip is worthwhile and you can get there by car, bus, rail or even a plane in anything from an hour to 90 minutes. This is one of the most beautiful places on the Eastern Seaboard, if not in the whole of the USA, with the islands of Martha's Vineyard and Nantucket drawing wealthy residents from across the world. Take a swim off one of the glorious beaches, tuck into plentiful seafood and make it an overnight stay. The Cape Cod ice cream is legendary. There is also an annual jazz festival in Provincetown.

    Labor Day

    This annual holiday falls right at the end of the month and the last weekend in August is always Labor Day weekend. It starts with a huge firework show lighting up Boston Harbour followed by a long weekend of festivals, concerts and other special events across the city and elsewhere. Take a special fireworks cruise on the Harbour to get the best view and afterwards, take your pick of the city's best restaurants before heading towards the sound of live music coming from the waterfront.

    Paul Revere House

    To understand why he is considered one of the greatest of American heroes, visit Paul Revere House to hear the story of the Midnight Ride, when he raced to Lexington in 1775 to warn to warn John Hancock and Samuel Adams that 'The British are coming!' Born in Boston's North End in 1734, Revere died relatively unknown aged 83 in 1813 and was only elevated to folk hero status after Longfellow's poem 'Paul Revere's Ride' was published 47 years later. The museum tells his story and that of Boston's role in the American Revolution.
