The 2017 Languedoc Rough Guide is sufficiently detailed and up-to-date to be a worthwhile investment. It is easy to quibble about particular interesting villages and historical landmarks that have been omitted, but any attempt to cover such a vast region in 360 pages is bound to have its limitations. Well written, interesting and a good mix of history and practical advice. Available from Amazon.co.uk and Amazon.com while earlier editions can be bought secondhand for 1p.
Lonely Planet’s competing 304-page Languedoc guide is out of print and was last published in 2009. A shame because the region needs more coverage in print and on bookshop shelves. Secondhand copies available sometimes from Amazon.co.uk and Amazon.com at variable prices.
