I'm not well-travelled so mine will appear quite modest but the view over the Julian Alps from the cable car at Bohinjska Bistrica (Slovenia) is quite something. I think my favourite is the view over Bishopdale and up Wensleydale, as seen from the bridleway and rocks on the western flank of Penhill in North Yorkshire. The landscape has a lot of depth and really fills the eye. I haven't been round there for years so I must go back some time.
