In this short film Iain Cameron, an expert in long-lived snow patches in the British hills, buzzes a drone around a very busy Helvellyn in sunny Easter holiday mode.

'A 20km walk in fabulous weather around the Helvellyn massif' says Iain 'filmed using a DJI Phantom Vision 2 Plus.'

Happy scramblers on Striding Edge; skiing on the Red Tarn face and Raise...

'Worth the sunburn and mild nausea!' reckons Iain.
