Renowned for its exuberant festivals and especially lively in the summer, Scotland's atmospheric capital, Edinburgh, is also well worth visiting out of season, to see Edinburgh Castle silhouetted against the blue spring sky with yellow daffodils gracing the slopes below; to see its graceful gardens strewn with autumnal leaves; or witness fog cloaking the spires of the Old Town, with rain on the cobblestones and a warm glow beckoning from the window of a pub on a chilly winter's day.
