Well since we are talking about it....
Summer of 76. I had just finished my A levels and a few of us spent the summer walking and wild camping in Scotland. The first week on Skye was very wet, but after we came back to the mainland the weather improved. It was so hot that we would get up at about 3 or 4 am, and aim to walk until about midday, when we would find a stream or some shade to keep cool. Any walking after that was really uncomfortable and, being up in the hills, the UV must have been high too. A bit more walking in the evening if we felt like it then pitch tents for an early night to catch the sunrise and start all over again. A really magical six weeks or so.
Those were the days before 'lightweight' camping and dried foods so the weights of our packs limited us to between 12 and 15 miles a day, less if we included some of the higher peaks but we still covered a lot of ground that year. It doesn't appeal to all but we really enjoyed 'disappearing' into the hills and then going for days seeing only a handful of others.
