Scotland rewards visiting in every season, and the right one depends on what you've come for. Spring brings quieter roads and returning wildlife, with golden eagles, puffins and orcas reappearing and primroses and bluebells along the verges. Summer is peak season, with longer days and a calendar of Highland Games and military tattoos. Autumn turns the woodlands to yellow, orange and red. Winter gives the islands steely seas and dramatic skies, the chance of the Northern Lights, and centuries-old celebrations from Hogmanay to Burns Night.
