I have read a good number of the guidebooks to the Languedoc Roussillon region and this is my favourite. While relatively compact and light, it packs in plenty of information and the recommendations on places to go and see are both helpful and reliable. Best of all, it's written with enthusiasm and an eye for the small details that make for holiday highlights.
The book opens with photographic highlights of the region accompanied by quotes from travellers about their experience in those destinations. It gives you an immediate taste for what the region has to offer and a hankering to visit. There are then a number of suggested routes and highlights, which are very helpful when planning your trip (including recommendations for families and recommended drives). Each section also contains suggested highlights for that smaller region.
While descriptions are often brief, they are accurate and convey a very good flavour of each destination. For example, on a recent trip we were tossing up between staying in Perpignan or nearby Narbonne. Many books I read made them sound very similar which wasn't very helpful in guiding our choice, but the Lonely Planet differentiates them clearly. Based on places where I have stayed or eaten, the accommodation and dining guides are accurate. We thought the food at L'Epicurian in Albi was fantastic and I was pleased to see it included here.
If you are tossing up between this book and the Rough Guide to the region, I recommend the Lonely Planet. The Rough Guide is more detailed and may be better if you are planning an extended stay in the region, but the Lonely Planet guide covers all the region's highlights and is a much more enticing read.
