For anyone with Celtic roots, then a must-do event while in Europe has to be the Inter-Celtic Festival in Lorient, Brittany.
Every July, thousands of people with a Celtic connection gather in this port city on the southern coast of Brittany and enjoy up to ten days of drinking, dancing and music. The festival pulls in people from all seven Celtic "countries". That's Asturias and Galicia in Spain, Wales, Scotland, Ireland, Cornwall and Brittany.
Whether you're a Guinness or Scotch drinker, or if your palate is more in favour of French wine and cider and Spanish wines, your drinking tastes will be catered for here. And you can fill up on wholesome Breton food too; plenty of crepes, savoury and sweet, and seafood.
Many of the events take place around the central square of Jules-Ferry, but you'll find things going on all around Lorient during the festival period. If you're planning on visiting Lorient during the Inter-Celtic festival, you'd do well to book accommodation well in advance, as places fill up fast. Many people end up just sleeping where the action is – in place Jules-Ferry.
However, there are plenty of campsites within easy reach of Lorient, and French campsites are really way better than some of the ones you may have experienced in the UK – which gives camping a bad name.
Usually the weather will be good in Brittany during Lorient's festival – but don't take it as guaranteed. You can sometimes get a week of drizzly rain – similar to the kind of sea-driven weather that can hang over Cornwall at any time of year. The schedule for each year's festival is set in May, so you can contact the Pays de Lorient tourist office for festival schedules from then on, as well as information on places to stay.
If you haven't prepared ahead, you can still rock up and find a warm welcome. You may even benefit from some late deals on accommodation, but be prepared to travel in and out of the centre unless you've booked really early.
