I recently walked up Moel Siabod in Snowdonia.
I don't take a "proper" camera with me on these walks anymore, the iPhone 4s is more than good enough.
Also 3G is pretty good in most of Snowdonia, especially on the tops, so I can post to the likes of Instagram immediately.
This is a view from the summit of Moel Siabod looking towards Snowdon and the Glyders.
Moel Siabod is a superb walk. the scramble to the summit is about the same as Tryfan, but obviously not as long. there are a couple of more tricky parts towards the summit, but these can be missed out by easier routes if desired.
Image was shot using the standard iPhone camera and processed in Nix HDR to give it a bit of a boost.
