Prince William has been back at work after last week's wedding frolics, carrying out two mountain rescues in Snowdonia.
The Anglesey-based future monarch was involved in a helicopter airlift of one man off Y Lliwedd, a 2,946 ft peak on the Snowdon Horseshoe.
And he then helped four men off the narrow Crib Goch ridge as one of them was suffering from vertigo.
Prince William is currently based at RAF Valley and part of his work involves regular missions to support ground-based Mountain rescue services in north Wales.
Those putting on walking trousers
and heading for a narrow ridge like Crib Goch may need to be careful if they do not have a head for heights, as it is highly exposed.
Other exposed ridges in Snowdonia - which may appeal to scramblers - include the Bristly Ridge on Glyder Fach and the north ridge of Tryfan, with the latter mountain requiring prolonged scrambling to reach the top from any direction.
