There are several webcams on-line from locations around the Peak District. The following are links to some that I know of:
Cat and Fiddle pub (Looking NNW across Manchester from the 515m summit of the A537 Buxton to Macclesfield road)
Harpur Hill, Buxton (Looking NW at about 350m above sea level)
Flash Bar (Looking SW from Flash Bar at about 465m towards Flash)
Kinder Scout (Looking east from the valley east of Hayfield. Highest point visible on right end of ridge (when not covered by cloud!) is Kinderlow End at about 585m) – After being unavailable for more than a week this webcam came back on-line on 14th Dec 2018.
