Helfa Gelf (en: Arts Trail) is the Welsh-language name for the largest open studio event in north Wales, with more than 300 artists. The annual art event has been held every September since 2006, now extending over five counties of North Wales. The Art Trail combines over 100 artists Open Studios and Artists Open Houses with events located all kinds of venues: studios, galleries, village halls and even garden sheds.
Although it is an independent body, it seeks much external sponsorship, and is organised in co-operation with many bodies including county councils, the Arts Council of Wales, Betsi Cadwaladr University Health Board, Anglesey Arts Forum, Royal Cambrian Academy, Oriel Plas Glyn Y Weddw, Bodelwyddan Castle, Gwynedd Economic Partnership, Menter Môn and Cadwyn Clwyd.
A Helfa Gelf Art trail guide book is available free from local libraries, schools, tourist information centres, hotels, shops, galleries and other locations; it contains information to plan an art trail. 2011 artists included Laura Capper, Alwyn Dempster Jones, Ann Bridges and Eleanor Brooks.
Applications for Art Trail/Helfa Gelf 2013 are open until 1 March 2013.
