Autumn brings a good excuse for gourmet travellers to pack their bags and explore local flavours with a wave of festivals celebrating the season's bounty throughout the UK and across Europe.

The Abergavenny Food Festival (abergavennyfoodfestival.com; 18-20 September) features talks and demonstrations from tastemakers such as Yotam Ottolenghi, Raymond Blanc, Tom Kerridge, and Hemsley and Hemsley, as well as a huge food village and countless events.

At the same time, Guernsey will host its first International Festival of Food (visitguernsey.com/foodfestival; 18-27 September).

Over in Ireland, the International Galway Oyster and Seafood Festival (galwayoysterfestival.com; 24-27 September) is one of the world's longest-running oyster celebrations, now in its 61st year. Sample native oysters from Galway Bay and see who takes home the coveted World Oyster Opening Championship trophy.

Sicily's unique cultural heritage extends to its cuisine, with many dishes heavily accented by its North African neighbours. San Vito Lo Capo Cous Cous Fest (couscousfest.it; 18-27 September) celebrates the humble yet versatile grain. As well as talks and demonstrations, highlights include the Italian and World Cous Cous Championships.

Truffles are some of autumn's most highly prized bounty, and Alba Truffle Festival (fieradeltartufo.org; 10 October to 15 November), in the northern Italian province of Piedmont, is one of the most prestigious places to sample the highly prized white variety. Chefs and restaurateurs from all over the world spend thousands to secure prime examples at the daily truffle market here.
