The UK’s biggest national park is home to its mightiest mountains: five out of six of Scotland’s highest peaks are found here. Lying in the heart of the Highlands, the Cairngorms mountain range still has vast tracts of pure wilderness and is one of the chilliest places in the country. For much of the year, its peaks are blanketed in snow and you can ski there in winter. Red squirrels, red deer and rare woodland grouse roam its ancient Caledonian pine forests.
