Let's Go was a travel guide series researched, written, edited, and run entirely by students at Harvard University. Let's Go was founded in 1960 and headquartered in Cambridge, Massachusetts.
The first Let's Go guide was a 25-page mimeographed pamphlet put together by 18-year-old Harvard freshman Oliver Koppell and handed out on student charter flights to Europe.
In 1996, Let's Go launched its website, Letsgo.com, while publishing 22 titles and a new line of mini map guides.
Let's Go announced a new print publisher, Avalon Travel, upon the expiration of its contract with St. Martin's Press in 2009. The switch led to a new format for the insides of the books, new retro covers for the outsides, and a rebranding to emphasize Let's Go's student origins. The theme has been changed in 1999, 2002, 2005 and 2009. In 2014, Let's Go began self-publishing for the first time since 1970.
Production of Let's Go was suspended in 2020 as a result of the COVID-19 pandemic, and never restarted.
Let's Go has used many words to describe the style of its content. "Witty and irreverent" is possibly the most frequently used descriptor; the company takes pride in its youthful, casual, sometimes zany tone and trains its writers to avoid "brochure-ese". Let's Go also promotes the unvarnished opinions of its reviews, stating that they want the takeaway of every single listing, good or bad, to be clear to the reader. This honesty led to a lawsuit against Let's Go in 1990 as a result of a scathing review of an Israeli hostel, but the travel guide was victorious in court, upheld by the judges as "the modern equivalents of Thomas Paine or John Peter Zenger." Other traits the company has emphasized include its budget roots and social consciousness.
As of the 2019 series of guidebooks, Let's Go has published 75 titles covering six continents. The books range from country guides to adventure, city, budget, and road trip guides, many of which are still updated annually. Let's Go also published 20 abridged, pocket-sized "map guides" (Amsterdam, Berlin, Boston, Chicago, Dublin, Florence, Hong Kong, London, Los Angeles, Madrid, New Orleans, New York City, Paris, Prague, Rome, San Francisco, Seattle, Sydney, Venice, and Washington DC).
Because Let's Go employees are all students when working for the travel guide, many of its alumni have gone on to careers in travel writing and other areas.
