Get outside
With the leaves of unusual plants laced with frost, ponds frozen to glass and rows of evergreens creating a Narnia vibe, formal gardens can be their most enchanting in winter. Follow a trail through 170 holly trees at RHS Rosemoor (£13 adult, £7 child) in Devon, or see a fantastic collection of towering conifers at Ardkinglas Woodland Garden (£5 adult, £2.50 child) near Loch Fyne in Argyll.
