October heralds the season of mists and mellow fruitfulness: the perfect time for trips that embrace the natural world, its changing hues and abundant produce. From mushrooms to apples, pumpkins to olives, tours across the UK and Europe are ripe with foodie opportunities, whether encountered through a harvest or on a foraging course.This is also a great time to be bagging the last beach break of the season while easy access destinations in Southern Europe, North Africa and the Middle East are still basking in sunshine and coastal resorts and seasonal ferries have yet to shut up shop. But if you're weary of sun and sand, October also comes with some tempting urban escapes. From Montreal to Manhattan, Boston to Baltimore, cities along North America's east coast are at their most atmospheric this month, rich with fiery autumn colours and Halloween festivities.
