For years a fringe movement, veganism has now hurtled into the mainstream, with recent research suggesting there are as many as 3.5m of us in the UK. While the merits and ethics of veganism remain divisive (and don’t I know it!), there’s no doubting that it has become big business. Plant-based restaurants, shops, festivals and organisations are popping up all over the world, catering as much to vegan travellers as to locals. Having travelled extensively as a vegan, I can attest to the growing number of specialist itineraries — and to the growing acceptance.
