So I was left to my own devices and I ended up revisiting a place that Pete and I had been to during the day to do some landscape shots - Cwm Idwal. I decided on this as I had already familiarised myself with the landscape and footpaths and this was going to be very useful as I wandered around in the dark.
I'd prepared reasonably well by packing a couple of torches and warm clothing and I'd recently bought the PhotoPills app for my phone which helped to show where the Milky Way would be in the sky and at what time. I'd also be practicing taking photos in the back garden to get familiar with my camera controls when you can't really see your hands in front of your face.
Surprisingly though, it wasn't quite as dark as I'd expected because there were some lights in the nearby cottages and the odd car passed by on the A5 road below me. But what really opened my eyes as I stood on the bridge looking over the Afon Ogwen Falls, was the number of people who were wandering about in the dark at 11pm at night! There were headlamps camping on top of Pen yr Ole Wen and Tryfan, lights coming down the steep slopes of both mountains and people going up to Cwm Idwal to wild camp overnight.
