Just an hour’s train ride from Nice lie the otherworldly wonders of the relatively unknown Mercantour National Park. Incorporating large swathes of the Alpes Maritimes and Alpes de Haute Provence, this is hiking and horseriding heaven. Follow 600 km of waymarked ways through ancient forest, up rocky inclines to heights of over 3000, through red sandstone gorges. Lose your money in Nice. Lose yourself on Mercantour holidays.
