After that first day of good weather, we decided to go back to the Ring of Brodgar at night. We took three other lone travellers with us who were staying at the same hostel, and went around 11pm. Too fantastic to describe, but it felt like you could touch the milky way. I wandered off alone around the ring - eyes as big as saucers in the dark - and said hello to a few of the stones. Priceless.
