The mountains are flanked by vast expanses of lush vegetation in Corsica’s celebrated maquis, dotted exotically (when we were there in May) with gorse, prickly pear, aloes, eucalyptus, juniper, myrtle, clematis, honeysuckle and the pink and white wild maquis cistus, all mingling with perfumed wild herbs. At higher altitudes, you’ll find chestnuts, one of Corsica’s great products, along with olives.
